Rotary Feeders for Powder and Bulk Material
Transfer dry material from storage containers into air-powered conveyors and other pressurized systems. As the rotor’s eight vanes turn, the pockets between the vanes fill with material from the inlet and then dispense material through the outlet. Controlled by a built-in electric motor, this movement delivers bulk material in a controlled manner while maintaining pressure differential between the inlet and outlet. The rectangular flanges have standard bolt holes, so these feeders fit into most air-powered systems. Included neoprene gaskets are sized to fit the flanges to form a tight seal. To calculate the fixed displacement rate needed for your application, divide your material movement (lbs./hr.) by product density (lbs./cu. ft.).
316 stainless steel feeders have excellent corrosion resistance, so they’re a good choice for handling abrasive or corrosive material.

Pressure-Relief Airlocks
On containers filled with water, these airlocks create a liquid seal that keeps contaminants out while letting gases produced by chemical reactions and temperature changes escape. They’re common in fermentation applications, such as beer brewing and winemaking. Use them with venting flasks, carboys, and other containers that are sealed with a rubber stopper; to install, push the stem into the rubber stopper’s hole. At the top, these airlocks have a cap that blocks dust, but still lets gas out. When it’s time to clean them, they come apart in three pieces, so you don’t need a specially-shaped brush to reach every crevice.
