Hopper Hammer™

Our AVC Specialist brand Hopper HammerTM is an easy-to-install device designed to deliver optimal performance and efficiency to dislodge particulates from precipitators, hoppers, bins and bunkers (an any other conveyor that tends to have material clog, stick and create stoppages).

The discrete, variable rate, with high accelerations caused by the Hopper HammerTM are an advantage over the continuous but lower accelerations that are produced by electric or pneumatic vibrators which can compact the materials and work harden the hopper surface, leading to cracking and failure.

The Hopper HammerTM is designed to easily mount, plug into a 120VAC outlet and run. Four switches control the impact, runtime, raps/second, and interval between rapping cycles. Once these are set, install the cap to seal the unit, and let it run!

Since most applications such as hopper cleaning, require that the rappers only run when the outlet valve is open and running, we have a Remote Enable input.

Hopper Hammer from AVC

The CECO AVC brand has been a leader in the development, distribution, and maintenance of Electrostatic Precipitators (ESPs) since 1977. Our AVC brand manufactures top-of-the-line voltage controllers, rapping systems, and replacement components for ESPs and is used in industrial facilities around the world. AVC is an innovating force in the field.

When material is removed by the Automated Voltage Controllers and accumulates, it can reduce the effectiveness of the ESP. AVC rapping systems, like the Hopper HammerTM, eliminate the problem by cleaning grounded plates and remove particulates effectively. This allows ESPs to perform at peak efficiency. Disposal of fine particles swiftly and responsibly in a variety of environments are ensured by our rappers. We keep the gasses clean and flowing. At every stage, AVC brand has it covered.

Industry leaders in biomass power, petroleum refining, chemical product manufacturing, and cement production come to us for parts and systems. If it deals with ESPs, we are the one to call.

AVC provides expert clean/dirty inspections, repairs, and upgrades to confirm and safeguard that your equipment remains state-of-the-art. Our resources and know-how are unparalleled in the industry. That is why we are trusted worldwide in some of the most strenuous and hazardous conditions.

At AVC, we make the best products for the best people.
