Bjerke Brothers, Inc. Aspirators provide an effective solution for dust, fines and chaff removal. Two basic models are available: Open Circuit, which uses the external dust control system to provide a fresh air supply; and Closed Circuit, which uses integral fans to provide a supply of recirculated air. In both models the air supply is pulled through the product stream to lift and separate fines from the product mass. NS Aspirators are available in widths from 24″ to 115″ and in various body styles.
Fixed- or variable-speed feed rolls for uniform feed rate and positive shut-off on selected models
