Air handling

Dust and fume extraction equipment firm Egmont Air has created a new solution to remove dust, smoke, and fumes from the workplace.

As the focus on health & safety, and clean-air-discharge increases, new extraction methods are required that produce better results in maintaining a clean and healthy workshop – as well as an environmental responsibility to keep New Zealand sustainable and clean for future generations.

Plasma, welding, spray-painting, chemical and similar processes generate a high volume of contaminates that can quickly spread through a working environment.

Egmont Air’s extraction systems quickly capture and provide a high level of filtration efficiency so that toxic particles are contained and eliminated from the environment.

Cartridge filtration is the leading technological answer to many tricky dust and smoke applications because the ability to achieve high-efficiency filtration on micron particles such as smoke, yet process a generous dustloading of contaminants outplays all other types of filtration methods.

Cartridge filtration is the leading technology in the dust & fume extraction industry and offers many advantages and benefits over traditional filter-bag systems, such as: High efficiency filtration, (even on micron particles such as fume and smoke) Automatic reverse-pulse cleaning by compressed air to maintain cartridges in optimum condition and reduce maintenance to a minimum. Fan on clean-side of filter, out of abrasive wear Down-f low air pattern through filter, for proper decantation of dust particles into drum. Staff at Egmont Air believe there is no substitute for a high filter-surface-area ratio and automated filter cleaning, and this is exactly what the firm’s extraction systems include.

Other design features are including depending on each individual application and these may be; spark traps, specialist media such as f lame-retardant or anti-static, decantation chambers for high dust-loading, acoustic silencers and vertical discharge cowls.

The firm says it will guarantee with documentation that these systems have high filtering-efficiencies and will not discharge dust particles that would otherwise cause harm or nuisance to the environment and neighbours.

Smoke and fumes

Smoke and fume extraction from industrial processes such as welding smoke, plasma fume, foundry, extruders, chemical, odour control, machining oil mist, etc can be extracted before it reaches the operator’s breathing zone – or spreads throughout the workshop environment.

High-efficiency filtration and large filter surface is important to capture micron particles without clogging or binding of filter media. Egmont Air follows a 17 step process to correctly evaluate your specific application before recommending any extraction system.

Cartridge dust collectors, extraction hoods, articulating arms, fume cupboards, air cleaners, robot fume extraction hoods and mobile fume extractors can be utilised in the design of the extraction system.

Mixing, pouring and conveying processes often generate airborne dust. These fugitive dusts can usually be captured by strategically placed hoods, down-draught suction benches, articulating arms or a central extraction system.

A full analysis of the dust or powder being extracted is always important to allow for any special design features that may be required for explosive dusts, corrosion, hydroscopic properties or statically charged particles.

In these situations Atex certification, explosion relief panels, special filtermedia options or spark detection and suppression, will be incorporated into the extraction system design.

Paint and powder coating

A full range of spray painting booths, enclosures and extraction systems are available to suit most industrial manufacturing type applications. Particularly where a high volume of paint or lacquer is being applied, handling of items requires mechanical forklifts or gantry, or perhaps large batch and production f low movement of items is required.

In these instances Egmont Air has systems that feature high filter-surface area to capture the sticky overspray and also generous ventilation to remove hazardous fumes.

Small spray paint stations are also available for small items in school or test-sample situations. Wet scrubbers, paint-mix rooms, drying rooms, bakeovens, powder-coating booths are also available. Of course all systems are certified to AS/NZS 4114.1 spray-booth standards.
