NFPA Compliant, Heavy-Duty Self-Cleaning Rotary Valve Airlock

The industry’s first NFPA-compliant, Self-Cleaning Heavy- Duty Rotary Valve Airlock!

PMM’s Heavy Duty, Self-Cleaning, Rotary Valve Airlock is equipped with an upper and a lower “clean out” rotor, which is perfectly synchronized to clear the upper rotor pockets and prevent material buildup in the rotor.

Manufactured from an abrasion-resistant, through-hardened steel alloy, which is surface-treated pushing the hardness to nearly 60 Rockwell, the heavy-duty Self-Cleaning Rotary Valve Airlock is an absolute game changer!
