Air Piston Vibrators

For trouble-free material flow in storage bins and hoppers, chutes, and on feeders and screens.

The BH model industrial air piston vibrator by NAVCO^® incorporates a nominal piston and bore. During operation, compresssed air is alternately directed from one end of the piston to the other through a series of internal ports. The piston is the only moving part, which makes a pneumatic air piston vibrator a reliable, low maintenance flow solution. The bin vibrator housing is a one-piece, ductile iron casting. This adds to the durability and reliability of NAVCO^® Pneumatic Air Piston Vibrators. The action of the piston in our industrial vibrator generates high amplitude vibration with unidirectional, or linear, force vectors.

NAVCO^® manufactures a range of over 30 sizes and options for the
BH Air Piston Vibrator for various applications.
