Electrostatic Precipitator Rapper Vibrator

Pneumatic Rappers Improve
Electrostatic Precipitator Efficiency

NAVCO® Pneumatic Rappers remove dust from collecting plates, discharge electrodes, gas distribution systems and collection hoppers in electrostatic precipitators (ESP). Engineered for operational reliability, durability and overall dependability across a wide range of climate conditions, these rappers ensure ESPs are able to perform at their intended efficiencies.

Designed for Electrostatic Precipitators

Repetitive Impacts for Challenging Applications

NAVCO repetitive impact Pneumatic Rappers transfer a continuous forced-frequency impulse into the electrodes, producing a uniform high acceleration response. This offers a more complete electrode cleaning than single-impact rappers, making them ideal for applications such as:

High-resistivity fly ash in the power industry

Salt cake in the paper industry Cement dust for both dry- and wet-process kiln precipitators and lime-kiln precipitators Smelter furnaces, BOFs, sinter plants, roasters and other primary metals applications

One Piece Rapper

NAVCO’s patented one-piece housing, designed to mount on a tapered shaft, allows for easy installation. The tapered mount further ensures a large installation surface to transfer the Rapper energy.

PTFE Coated Piston and Bore

PTFE coated internals resist corrosion, reduce friction and prevent rust seizures. Enabling a long, low maintenance operational life in tough industrial environments.

Mountable in any Direction

Designed to be mountable vertically, horizontally, and everywhere in between, Pneumatic Rappers are able to be placed at the optimal position for every application.
