Advancements Made to Paper Trap Technology

EnviroAir Improves on Patented System

Eagle, Wi - January 20, 2012 - Wisconsin based, EnviroAir, Inc. recently introduced improvements to their patented, self-cleaning paper trap. The paper trap captures tissue broke collected at our dust capture hoods and floor sweeps to prevent the tissue broke from plugging downstream dust collectors.

EnviroAir saw the need for further improvements when they discovered newer tissue grades were not cleaning as well from paper trap media.

The new paper trap improvements include a re-engineered media design with larger openings and new blow-off nozzle design to enhance the strength air jets in the system.
