Donaldson’s new Downflo® Evolution (DFE) dust, fume and mist collection filters

Clean up your machining, laser and plasma cutting operation.

For years, the government and other organisations have studied the risks of exposure to dust in industrial settings as well as the use of oils, grease and lubricants in metal cutting and forming. For decades, Donaldson has offered manufacturers advanced and reliable dust, fume and mist collectors engineered to provide outstanding filtration efficiency and energy savings. The application of these industry leading collectors and filters helps increase manufacturing efficiencies and cleaner environments for employees.

Plasma and laser cutting machinery produces hazardous metallic fumes in the cutting process. It doesn’t matter if you are using a plasma with a conductive gas and a torch head or a high-power laser to cut that material, both processes produce highly toxic fumes. The need for an efficient dust collector in these applications is critical for the health of the people working around the area and to the environment.

Donaldson Filtration specialises in the design, manufacturing and distribution of a variety of air pollution control products, including dust, fume and mist collectors. Depending on the size and space specifications of your facility, Donaldson can provide systems to meet your needs.

Many compact units are available, with designs intended to minimise the space needed in your facility. Donaldson sales engineers help you select the models that are ideal for your application, with many different options available, to ensure you are compliant with Air Quality Standards and OSHA regulations in your industry.

Donaldson’s new Downflo® Evolution (DFE) dust collector range sets the benchmark in dust collection standards. Regardless of the type of dust produced in your facility, the DFE is effective for a wide variety of applications, including metal grinding, plasma cutting, laser cutting, welding and metal manufacturing.

This DFE can use 40 per cent fewer filters than other cartridge collectors. Because of its decreased footprint, property managers can purchase these at lower prices and spend less on filter replacements. The unit is designed to help maximise available floor space, leaving plenty of room for additional machinery.

The unit’s design also features a Max Pulse cleaning system that produces 27 per cent more cleaning energy, an Ultra-Web® Merv 15 triangular filter, and an innovative inlet air management system. Like other Donaldson filter equipment, it’s easy to maintain and offers optimal performance with lower running expenses.

Donaldson has developed a broad range of smoke collectors, mist collectors, and mist filters that remove submicronic contaminants from the plant atmosphere. Donaldson offers a full line of collectors from a single source machine mounted unit, all the way to a central mist collector. Donaldson’s WSO® Mist Collector with its unique Synteq™ XP filter media is an extremely versatile collector for all operations. It can provide a solution for water-soluble coolants, straight oils, or operations that have oily smoke. If your machining operations change, the only modification is a filter change.

With increased pressure for delivery and tooling speed, the number of contaminants in manufacturing plants has also seen an increase. The result, an ever decreasing indoor air quality, requiring new controls to reduce airborne mist levels. Donaldson dust collection equipment and filters are ideal for collecting dust and fumes produced from most metalworking processes.
