    Note: All standard Feeders (Airlocks) are designed to handle material in conveying systems that operate up to a maximum pressure differential of 5 PSIG (1.05 Kg/cm2).

  • Open End Rotor

    General
    The DA Feeder introduces material into the conveying system at highest volumetric efficiency when material flow into the feeder is controlled to permit free venting. The feeder may be used under a head of material when appropriate aeration is provided to create a path for relief of the reverse air flow. In operation, air enters a single inlet and passes into the rotor pocket through two (2) ducts integrally cast in the end plates, assuring complete fluidization and discharge. High efficiency is attained through the combination of gravity and air-sweeping of the fluidized material into the conveying line. This design principle assists greatly in discharging materials which have a tendency of hanging up in the rotor pockets. DA Feeder permits the use of smaller sized components and related equipment in pressure pneumatic conveying systems resulting in savings in initial equipment cost, installation cost and space requirements.
    Available with or without motor drive, discharge pan and support base

    Body
    The DA Feeder is constructed of machined #50 cast iron and incorporates a deep packing gland, outboard anti-friction bearings and an extra heavy shaft. Lantern rings are provided to permit use of purge air when handling fine, powdery material to prevent contamination of shaft packing.

  • Open Te Rotary (Airlock)

    General
    When installed in a pressure conveying system, the use of (optional) Lantern Rings and (standard) Air Purge is recommended when fine powdery material is being conveyed to prevent contamination of packing and bearing. The air purge should be set 2 to 4 PSIG (.14 to .28 Kg/cm2) above conveying line pressure.

    Body and End Plates
    The body and end plates are heavily ribbed and constructed of #50 cast iron. Motor support lugs are cast as an integral part of body and permit the mounting of the gearmotor directly on the unit, resulting in a compact package.
