Tough materials that are sticky, coarse, and high in moisture content require linear force to flow freely. Powerful MARTIN® P-Series Pneumatic Piston Vibrators provide the force that activates the free flow of such materials.

A MARTIN® P-Series Pneumatic Piston Vibrator will operate in virtually any position once it is started. If adverse temperatures (150° to 250"F) prevail, or if the vibrator is infrequently used or mounted horizontally, a piston starter spring is recommended.

When noise levels of the standard piston units are objectionable, specify the air-cushioned model. This noise reduction feature eliminates metal-to-metal impact, staying well within OSHA requirements. A “Q” in the model number of a MARTIN® P-Series Pneumatic Vibrator designates it is an air-cushioned unit. All air-cushioned units are equipped with a piston starter spring to ensure instant starting.

All MARTIN® P-Series Pneumatic Vibrators must be operated using filtered and lubricated air.

MARTIN® P-Series Piston Vibrators
The economical answer to sticky, coarse or high-moisture material. These maintenance-free units never need service when used with filtered/lubricated air. Available in three sizes with options to match your requirements.
