Leaking Seals

Is the inability to change sealing mechanisms while in operation due to their inconsistent lifespan, leading to the avoidance of maintenance?

Abrasion

Is the premature wear due to vanes opening up clearances resulting in a shortened lifespan?

Lead-Time

Are lead-times out of control? Down and in need of fast assistance?

Compliance
Solutions

Are there safety concerns related to NFPA compliance?

MAP Seal System

Rotary Airlock's Proprietary & food safe seal system. Built with maintenance in mind this end cap configuration touts a piloted flange bearing and the strength of outboard bracing giving you plenty of clearance to access your seal system, both of which can be changed in-line with no need to pull the airlock. With this seal system, you'll never use any other seal again!
