FP Series Pneumatic Piston Vibrators are explosion-proof, lightweight, compact, durable, efficient, and quiet. They are easy to install and maintain, and are designed to work continuously in the most rigorous conditions. Hard-coated alloy bodies are corrosion resistant for long life. The FP’s produce a linear vibration, with forces as low as 7.2 pounds to over 320 pounds, and frequencies from 2400 to 9300 VPM, depending on the model and air pressure. FP Series Pneumatic Piston Vibrators can be mounted in any position, and amplitude and frequency are infinitely adjustable by varying the air pressure. The piston is air cushioned, and a unique exhaust system absorbs noise for quiet operation. The power to weight ratio of the unit makes it ideal for many applications, especially the feeding of chemical powders, seeds, grains, small parts, flour, sugar, and other food products.
