How to Choose a Portable Vacuum for Metal Dust Extraction

In any workplace, dust is hazardous to health. However, some dust poses more than an inhalation risk; it could start a fire, or even cause an explosion. Metallic dusts, such as aluminium, titanium and magnesium, are quick to ignite when finely divided. Even non-combustible materials can become susceptible when airborne, which is why it’s important to invest in dust extraction equipment.

Combustible dust could be ignited if there was a spark, open flame (even from a cigarette), radiation, heat, static or a lightning strike. This could cause an explosion or a fire. While some of these causes may seem unlikely, you must assess the risk in normal operating conditions. Where there is any risk, you will need a metal dust extraction system to contain the dust and render it inert.

Understanding ATEX Directives

dynabrade-61462 The European Union has published two directives about dealing with an ‘explosive atmosphere’, known as ATEX Directives. The directives define different environments as zones, according to the size of the space, its characteristics, and the likelihood of an explosion. It is a rough equivalent to the HAZLOC system used in the USA.

Metal dust extraction equipment is marked with a category number, plus the letter ‘D’ for dust. There are three different zone definitions that you’ll need to be aware of when looking for the right category of ATEX certified metal dust extraction equipment:

Zone 20 describes a very high risk of explosion from a cloud of dust, where the risk is continuous or long-term; you will need Category 1 equipment
Zone 21 describes an area where dust is likely to create an explosive mixture occasionally; you will require Category 2 equipment
Zone 22 describes an area where an explosive mixture is unlikely, or would only exist for a short time; for this zone, you will require Category 3 equipment

There are some situations where Category 1 equipment can be used in Zone 21, and where Category 1 or 2 equipment can be used in Zone 22. Consult the Health and Safety Executive for guidance on your specific circumstances.

Understanding Atmosphere Ratings

Different metal dust extraction machines are designed for different substances, with three specific Groups relating to dust extraction. It’s important to check that the machine you want to buy is rated for the type of dust you are working with:

Group E: Combustible metal dust
Group F: Combustible dusts from carbon-based materials such as coal and charcoal
Group G: Wood, plastic and other combustible dusts not covered in category E or F

Many machines cover more than one Group; some are suitable for general usage. Check the product description carefully, and consult the manufacturer’s manual for guidance on each Group.

How Metal Dust Extraction Machines Work

Metal dust extractors contain and remove dust using a vacuum and a tank. The tank contains liquid to contain the collected dust. Depending on the machine, the liquid will normally be water, paraffin oil or mineral oil.

A metal dust extraction machine can hold between 2kg and 10kg of dust in up to 30 litres of liquid. The tank on most machines is detachable for simple disposal; some units have a disposable or reinforced bag, although this is optional.

Machines can be electric, or pneumatic. Pneumatic machines are advisable for hazardous environments where sparks may ignite airborne dust. Additionally, when choosing a metal dust extraction machine, make sure you choose the correct type of capture: dry or wet. Dry is for use with ordinary sanders and grinders, while wet capture equipment is for tools with a water feed. For general purpose, you can purchase machines that dispose of both wet and dry dust.

Some dry metal dust extraction machines have a coalescing filter element (CFE) fitted. These filter elements remove moisture from the captured material.

Metal Dust Extraction Machine Features

At DynaShop the complete range of Dynabrade “Raptor Vac” Portable Vacuum Systems. These portable machines are certified as Category 2 and/or Category 3 machines. Some machines are legally certified in their ability to dissipate static electricity, and have a conductive case for safety; others are non-conductive for general purpose use. All units are leak tested with aerosols.

For flexibility, portable vacuums allow you to tow the equipment around and stow tools alongside the machine, or on the shelf on top. Some machines allow the connection of two tools simultaneously; ideal if you are working in a small space. While these machines vary considerably in size, the cart allows them to be moved freely. Carts can be purchased separately if required.

Manufacturers also offer ‘backpack style’ portable vacuums that are worn on the body for convenience, as well as machines that can be mounted on a wall or another cart. These machines are smaller and lighter than the models on wheels, and can be used with a bag for simple disposal.

back-2 — Metal Dust Extraction: Backpack Style

A HEPA filter will prevent the redistribution of fine dust into the working environment. Some metal dust extraction machines offer automatic HEPA filter cleaning, using clean air to blast the filter at frequent intervals. For this Bypass Motor System feature to work, the machine must be connected to an external air hose.

HSE Guidance on Use of Emery Cloth on Lathes While Turning

Emery Cloth on Lathes and Polishing Lathes

If your business uses metalworking lathes, you need to be aware of a new guidance document from the Health and Safety Executive in the UK. Specifically, it refers to emery cloth on lathes and polishing lathes, and the tragic accidents that have occurred as a result of their use.

Emery cloth on lathes are used to deburr and polish metal as it spins, but operators sometimes use dangerous processes and risk serious injury or death. Putting items into a machine by hand carries significant risk, and many operators have broken bones or worse.

Due to the considerable risk of accident, it’s time to rethink your process and keep your workers safer, and this means discontinuing the use of emery cloths and replacing your machinery with Dynabrade alternatives.

The Dangers of Using Emery Cloth on Lathes and Polishing Lathes

Metalworkers use emery cloth on lathes and polishing lathes to polish their product. In the past, this meant wrapping cloth around the machinery as it turns, and holding the other end by hand.

This was thought to be the best way to maintain high tension against the metal being finished. But it can can result in the operator’s hand being pulled into the lathe when the emery cloth snags, or becomes entangled. This injury happens incredibly quickly, and gives the operator no chance to react before disaster occurs.

Simply wearing gloves is not an acceptable way to protect the hands, and will not prevent broken fingers or permanent damage to the arm.

Additionally, this manual process puts the operator’s body dangerously close to the machine. Operators can be at further risk if they have long hair or are wearing loose clothing, such as a baggy t-shirt. In this scenario, the risk is that a foreign object is pulled into the lathe as it spins, pulling the body towards it. Bracelets, pendants and other items of jewellery work on the hands can pose particular hazards.

To be compliant, all businesses using emery cloth on lathes or polishing lathes must carry out an immediate risk assessment. The Health and Safety Executive says that the use of these lathes should be discontinued. Your workers must use another method now. If you do not, your best option is to skip the finishing process entirely.

Fortunately, DynaShop can help. We stock two Dynabrade products that can replace these dangerous lathes safely and effectively, without affecting the quality and finish of metalwork.

Safe Dynabrade Solutions

The first solution is a Dynabrade hand held polisher. These tools have a contact arm, and the strap on the machine does the work.

The second option is a Dynabrade pipe grinder, where the tool is attached directly to the lathe. DynaShop stocks this air powered pipe grinder, which is available in .7hp, 1.2hp or 2.0hp variants.

Remember: all Dynabrade tools are imported by the USA by DynaShop. Everything is covered by a lifetime warranty to protect your safety and your investment. You can read more about Dynabrade grinders in our Ultimate Guide.

Best Practice for Using Emery Cloth on Lathes and Polishing Lathes

The Health and Safety Executive has issued an Engineering Information Sheet on using emery cloth on lathes and polishing lathes in metalwork. To summarise, it recommends the following best practice is followed:

Emery cloths should be immediately phased out
Another tool needs to be sought as a replacement; the Dynabrade tools we’ve mentioned are compliant
Guards and safety devices should never be disabled on computer numerically controlled (CNC) metalworking lathes
Everyone working with emery cloth on lathes and polishing lathes should wear full body overalls, to avoid their clothing being trapped and pulled in
Any operator with long hair should wear a hair net
Any operator wearing rings, bracelets or long necklaces should remove jewellery before working near any machine
If any operator is observed working in an unsafe manner, they should be stopped and retrained

Further Assistance

Emery cloth lathes and polishing lathes have proven to be incredibly hazardous to health. Even when used carefully, a tangle in the emery cloth, in one split second, is all it takes to maim the operator for life. The consequences of an accident can be life changing, with disability and death an unfortunate possible consequence of an accident.

The Health and Safety Executive does not make laws, but it’s a good idea to follow its guidance to keep your operators safe, and to ensure that your operation would pass a HSE inspection.

Until you invest in a Dynabrade solution, we recommend that you cease the use of these hazardous hand-held emery cloth techniques.

The Ultimate Guide to Choosing a Dynabrade Orbital Sander

Dynabrade orbital sanders are industrial machines for fabricators and manufacturers. The disc on the sander spins while moving in a random pattern known as an orbit. This random movement gives surfaces a superb, smooth finish without leaving patterns or swirls.

The Dynabrade D3 orbital sanders are the most popular model with over 137 different tool variations for all types of application. These are:

Tool Weight – Vacuum Type – Pad Size – Orbit

For a more detailed explanation of Dynabrade’s range of D3 Random Orbital Sanders please read our guide.

Dynabrade Random Orbital Sanders (D3)

All models shown are central vacuum, also available as non-vacuum and self-generated vacuum. Models come in various pad sizes and orbits.

Dynorbital Supreme: Ideal for Heavy Duty Work

The Supreme Standard for Random Orbitals

Dynabrade 56854 5" (127 mm) Dia. Dynorbital Supreme Random Orbital Sander, Central Vacuum

Dynorbital Silver Supreme: Heavy Duty Work With A Lighter Feel

Supreme Power with Lightweight Comfort

Dynabrade 69008 5" (127 mm) Dia. Dynorbital Silver Supreme Random Orbital Sander, Self-Generated Vacuum

Dynorbital Spirit: Lightweight Yet Powerful

Medium Duty Sander with “D3” Advantages

Dynabrade 59039 5" (127 mm) Dia. Dynorbital-Spirit Random Orbital Sander, Central Vacuum

Dynabrade orbital sanders are available in a range of orbit diameters and pad sizes. The smaller the orbit and pad, the finer the finish will be. The larger the orbit, the more quickly you can work, and the more forceful the motion will be. For the best possible finish, a wet sander is the perfect choice.

Remember that a smaller orbital sander is better for tight curves, and you may have difficulty working with contoured surfaces if the orbit and pad are too large.

Dynabrade Safety

All Dynabrade tools have a lifetime warranty against manufacturer defect. Durability is built into the design. Dynashop sells all of the consumables you’ll need to keep your orbital sander up and running, including pads and spare parts for your machine. Lever throttles and speed regulators also help to keep your employees safe.

Inevitably, a Dynabrade orbital sander creates dust. To comply with Health and Safety recommendations, consider an orbital sander with a vacuum to prevent harmful inhalation. Self generated vacuums are used with dust collection accessories, also available from Dynashop. Alternatively, a wet orbital sander will reduce the amount of dust that is generated.

Dynabrade Orbital Sander Types

In this article, we’ll briefly run through the characteristics of each Dynabrade orbital sander. For clarification, click through to the individual product pages.

The Dynorbital Range

The 11” diameter Dynorbital sander features an air-powered motor capable of 2,500 RPM. Dynashop sells an optional side handle for this tool, which facilitates firm control and grip. Non-vacuum and central vacuum versions are available.

There is also a two-handed version of the Dynorbital, which is ideal for vertical use. The unit is available with or without a vacuum (self generated, or via a central hose). Different pad sizes and orbits are available, and models are available in 10,000 RPM and 12,000 RPM.

The Dynorbital Supreme is a flagship model in the D3 range, which boasts the highest RPM in the industry. It’s designed for the ultimate in comfortable use, with a contoured handle and insulation to stop the cold air from the vacuum being transferred to the operator’s hand.

The Wet Dynorbital Supreme is ideal for operators who apply water using a spray or nozzle. The machine does not have a water feed built in, and it also has a protective shield to minimise spray. Purchase it in Basic or Supreme versions, with a 3/16” orbit and 5mm diameter pad, or a 3/32” orbit and 2.5mm pad.

The Dynabrade orbital sander range also includes a Silver Supreme D3 model, a very modern take on the orbital sander design. Manufactured in steel, this sander has a patented, ergonomic grip with comfortable recessed lever, and is compact and manoeuvrable.

The Spirit Range

The range of Dynabrade orbital sanders includes the Dynorbital Spirit, an extremely compact and lightweight machine ideal for operators who find large sanders difficult to control. This key Dynabrade orbital sander can be used with or without vacuum, and is available in dozens of size and RPM combinations.

There’s also a HiVac version of the Spirit, which offers improved dust collection with fine sanding. It can be ordered with a 3/16” or 3/32” pad, and collects dust through the pad itself. It weighs the same as the Mini-Dynorbital below; just 1.3lbs (600g).

The Mini-Dynorbital Range

Dynabrade has repackaged its orbital sander into a tiny palm-sized form factor, giving users precise control and the ability to finish intricate shapes.

The Silver Supreme model weighs a miniscule 1.3lbs (600g), making it comfortable to work with and easy to manoeuvre. This grinder comes with a storage bracket and pad.

The Supreme Mini-Dynorbital is available in 5,000 RPM and 7,500 RPM models for intricate jobs and the repair of small defects.

The range of small Dynabrade orbital sanders features an offset model, which is sold on its own or with a number of accessories. This package is called the Versatility Kit, and includes two sanders, a 1 /4” die grinder and a 3 1/ 2” disc sander.

There is also a right-angle Mini-Dynorbital Dynabrade orbital sander that is packaged with a micro-finishing film disc. All additional discs and accessories are available through Dynashop in the UK. The Angle-Head Mini Dynorbital completes the range, providing the flexibility of a right-angled design with the convenience of an extended rear exhaust. It’s available on its own, or in two different Versatility Kits.

The Ultimate Guide to Choosing a Dynabrade D3 Random Orbital Sander

There are generally four different aspects you need to consider when choosing a Dynabrade random orbital sander.

Dynabrade D3’s

Durability – how heavy-duty is the work you will be using your Dynabrade random orbital sander for?

The D3 range of Dynabrade random orbital sanders primarily offer three ranges at different price levels, these being the Dynorbital Spirit, Dynorbital Silver Supreme and Dynorbital Supreme. The lowest tier is the Dynabrade Dynorbital Spirit, which is hands-down one of the best random orbital sanders on the market. Built for less intensive, light-to-medium-duty applications and for users with smaller hands, this sander is ideal for vertical and contoured applications. The Dynabrade Dynorbital Silver Supreme is intended for the middle of the market; incorporating the ergonomics of the Spirit, it offers the perfect combination of supreme power and lightweight comfort. The Dynabrade Dynorbital Supreme is the premium range, offering the best performance and durability; the ergonomics of the aforementioned models have been improved even further, and there are also increased vacuum capabilities. Impressively, the Supreme also maintains the highest RPM in the industry while operating on a work surface.

Dust extraction – do you need to extract potentially dangerous dust particles?

Dust extraction is becoming more popular due to the improvement in health and safety lesiglation in regards to protecting users from harmful dust. Random orbital sanders offer three different options in regards to dust extraction: non-vacuum, self-generated vacuum and central vacuum. Non-vacuum models offer no extraction at all; any dust which is produced will remain on the work surface and in the air, meaning likely inhalation by the user. Long-term exposure to dust particles produced by working on surfaces such as wood, metals, etc. can result in lung cancer, asthma and even COPD (source: HSE.) It is therefore recommended that customers purchase either self-generated or central vacuum models. Self-generated dust extraction involves attaching a reusable bag to the tool, with dust particles produced during sanding being extracted into the bag. This requires emptying the bag once it is close to capacity but generally protects the user from dust inhalation, as it is extracted as soon as it is produced. Central vacuum is the most efficient option, with the tool being attached to a central vacuum system via a hose and the dust being sucked away similarly to a hoover, offering the most protection to the user.

Pad size – how big does your Dynabrade random orbital need to be?

Dynabrade Dynorbital Sanders offer pad sizes between 3 – 11″ diameter, with the Spirit, Silver Supreme and Supreme coming in 3 – 6″ varieties. A larger pad size offers a higher surface area, quicker sanding, and in turn, faster job completion. However, a larger pad size is not always the best option; you must also take into consideration the surface on which the sander is likely to be used and whether a smaller diameter would be more beneficial, for example when sanding in intricate grooves and contours where a larger sander would be too bulky.

Orbit – how fine is the finish you require?

Orbit Levers

The orbit is the motion the sander produces when in use; a random orbital sander simultaneously spins the abrasive disc and moves it in an ellipse. These “random” movements minimise the chance of sanding over recently sanded areas, and therefore help to prevent the resulting swirl patterns while also leaving a smooth finish. Dynabrade random orbital sanders come in various orbits, but the most common options are 2.5mm, 5mm and 10mm, with a smaller orbit providing a finer finish, while a larger orbit (for example 10mm) will sand more aggressively.

There are therefore a variety of different options when choosing a Dynabrade random orbital sander, or any ROS in general, and it essentially comes down to the user, the application and the abrasive – no sander is perfect for every job. However, it is strongly recommended that you purchase a model with some form of dust extraction, as this will improve working conditions for the user and also improve efficiency as considerably less time will be spent cleaning up dust resulting from using a non-vacuum tool.
