Perfection has arrived! The NFPA-compliant heavy-duty rotary valve airlock, which is equipped with a hardened tool steel knife, has combined the shearing features of a Rotary Feeder, with the heavy-duty robust nature of a Rotary Valve creating what we believe to be the PERFECT Heavy-Duty Rotary Valve Airlock!

Manufactured from a through-hardened, abrasion-resistant, 500 Brinell steel alloy, which is surface-treated pushing the hardness rating to nearly 60 Rockwell. The knife-equipped Heavy-Duty Rotary Valve Airlock is unlike any comparable product available in the market today!

NFPA Compliant, Shearing Capabilities, Heavy-Duty Construction! The Perfect Airlock!
