Certified HEPA Filtration with NFPA 484 compliant heat sensor.

HAZDUST Wet Downdraft Bench with top-mount HEPA.

Putting HEPA Filtration in wet dust collectors in the past has been challenging because the aluminum fines would dry out in the filters after the machine was turned off. Over time the accumulation of aluminum dust became a fire hazard. A lot of manufacturers stopped offering HEPA filtration as a result. 

A safe solution for this is to install heat and fire sensors on the HEPA filter itself.
