Rotolok offer an Easy Release rotary airlock designed to allow just one person to maintain and easily clean the rotor. Being on rails saves on production downtime and reduces man hours. An inspection door can also be fitted in the valve body that provides access and surveying of the valve internals to check for wear.

Robust bodies and end covers can be manufactured from cast iron to stainless steel with open or closed rotors built to suit industry needs. Typical sizes range from 3.5″ to 20″ with other sizes made to order.

The general market place covers Cyclones, Bag Houses and Gravity Feed applications with pressures around +/- 3 psi
