Imperial Systems, Inc has introduced its patent pending Rhino Drum. This easy to use product replaces expensive and complicated airlocks. It withstands up to 7 psi in explosion testing, and it meets NFPA standards 69 and 654 for passive explosion isolation. Unlike an airlock, it requires no electricity, motors, or moving parts.
The Rhino Drum allows easy changeout with a twist and lock lid design that requires no tools. The Rhino Drum also replaces easily damaged material like flex hose with a metal collar that will not be damaged by heat in a fire. A slide gate can be closed to allow removal and emptying of the drum without interrupting normal dust collector operation.
