Rotary Airlock Feeder

Jeffrey Rader rotary airlock feeders deliver industry-leading performance, providing reliable material entry into high-pressure conveying systems with minimal air and pressure loss or adeptly serve as infeed and outfeed airlocks in low-pressure systems. Built for continuous-duty operation, each unit features an extra-heavy-duty, chrome-plated housing, a rigid helical-paddle rotor with hard-faced tips, and precision bearings for long wear life and consistent sealing. With thousands installed worldwide and a full offering of new and OEM-rebuilt models, Jeffrey Rader delivers unmatched durability, cost-effective reliability, and proven performance in the toughest applications.

Standard Features:

Housing stress relieved after fabrication, before machining.
Top knife for shearing material at infeed.
Stainless steel adjustment screws for top knife clearance adjustment.
Top knife cover to prevent material build-up on the top knife.
A large, hinged top knife access door for inspection, adjustment, and replacement of top knife. A safety switch is supplied to interlock to system as a back-up safety device.
Packing glands provide positive sealing on rotor shafts which are hard chromed in packing area for long life.
Access door provided in end cover for easy inspection.
Shaft-mount reducers and torque arm mount are standard.
Heavy-duty rotor and shaft assembly, with rotor mounted onto shaft with self-centering locking assemblies.
Adjustable brass seal rings on each end of rotor to maintain close tolerances and minimize air leakage.

Optional Features:

Torque arm brackets.
Optional drive arrangements.
Speed sensing to detect loss of RPM.
Anti-dusting baffle for infeed area of feeder.
Infeed impact plate to prevent excess wear on the feeder housing.
Sub-knife wear bar for protecting chrome or duplex stainless bore at infeed.
Bottom wear bar for protecting chrome bore at discharge. Wear bar can be rotated four times to extend wear life.
Tee injector and mounting base for material infeed into a high-pressure pneumatic line.
Various special materials and/or coatings to meet specific operating conditions.
Special preparation, primer, and paint as required.
