STARTER SPRING required for installations mounted ±25 degrees from horizontal (see below).

SIMPLIFIED DESIGN. Model AP air piston vibrators are manufactured from single piece, ductile iron castings. No long thru bolts are used in assembly that may cause premature failure. Pistons are hard chrome plated for long life.

TWO STYLES AVAILABLE. Impact and quiet air cushioned units are available. Direct impact units provide high energy output for the most difficult and sluggish bulk materials. Non-impacting, air cushioned units meet all OSHA requirements, offering extremely quiet operation.

OPTIONAL FEATURES. Permanently lubricated bore. Safety cables, mounting fasteners and weldable mounting channels are also available for air-powered piston vibrators.

INTERCHANGEABILITY with other competitive brands can be achieved with the addition of an "R" style rectangular base plate.

WARRANTY. The quality, workmanship and performance of B.E.S.T. type "AP" vibrators are warranted for one year, if installed and operated according to factory instructions.
