DFX Ambient Air Cleaners

Handsfree Fume Extraction for your Welding Shop

DFX Ambient Air Cleaner by Clean Air Industries

The DFX Ambient Air Cleaner Series by Clean Air Industries allows you to provide weld fume extraction Exploded view of DFX Ambient Air Cleanerand dust collection for your entire facility with no floor space used.

Space: The DFX is hung at 12-14 feet in a pattern that allows air coverage over your entire shop.  It creates constant air changes by “throwing” air to one another allowing for large coverage with small pieces of equipment.  You can literally watch the smoke float up and get carried away into the unit.

Powerful Motors: Most ambient air cleaners suffer from weak motors in the 0.7 HP to 1 HP range.  The DFX uses the most powerful motors in its class.  As filters get dirty, the motors need to work harder to pull air through dirty filters, requiring a filter change.  The DFX’s motors allow the time between these filters to far exceed the timelines of comparable units.DFX Ambient Air Cleaner in use

Handsfree: One of the main drawbacks of a source capture system (like a portable weld fume extractor) is that it requires the operator to position the fume arm or capture source correctly. The DFX eliminates this failure point by taking it out of the operator’s hands entirely and functioning automatically.

Reliability: With over 30 years of manufacturing industrial air equipment, we have units still in operation that are older than some of our employees!

Made in the USA: From cutting the steel to welding and powder coating, all Clean Air DFX Ambient Air units are manufactured in our facility in Rome, Georgia.
