Coperion K-Tron Aerolock™ Surge Hoppers are constructed of carbon steel with a primed interior, and stainless steel. They are flanged to match round inlet Aerolock rotary valves.
The clearance beneath the flange allows room for the vented shear protector, the AerolockTM rotary valve, and a standard outlet adapter. Features include a cloth filter vent, a coupling in the sidewall to accommodate a level indicator, and a sight glass in the hopper wall. The cover is made to suit the specific application or can be shipped without an opening to be bolted on - making it easy to field-modify for the device feeding into the surge hopper.
