EXEN air knocker RKV series can be used at various equipment suh as hopper, silo, chute, pipe to solve inside material clogging problems.
Especially, air knocker big impact is perfect for fine powder, powder, moisture and sticky material which is hard to discharge with using pneumatic vibrator.
Compiled with  ANNEX I and ANNEX 2B of EC Directive for Machines (2006/42/EC)/ EN ISO 12100-1.

It will perform and provide results on any necessary work type, especially effective against fine powders such as dust in the dust collector, toner, flour, lithium - ion battery and sticky or clinging materials in the hopper, chute, silo and pipes. The micro vibration created by air-vibration type will in fact deplete the air between particles, condensing the substance, which will in turn make it more difficult to discharge. In contrast, the impacts by the Knocker will successfully discharge the work even if the content is made of fine particles or those with sticky materials.

Easily adjustable impact power with our original variable technology, requiring just manipulation of air compression pressure
This original technology allows one Air Knocker to be effective in various work environment, against seasonal and content variations.
The ability of just one Air Knocker to accommodate ranges equaling multiple hammer types.

Minimal consumption of air. Reduction of electricity in your factory!
In comparison, the air consumption rate for one impact of EXEN Air Knocker is dramatically lower than that of air vibrating type from competitors. Switching to our Air Knocker from air vibrating type in the similar class alone will greatly save you electric bills on compressors that account for 30% of electricity usage.
In comparison to piston vibration type in the similar class, you will be able to realize 85% reduction of air consumption. (In-house comparison)

Simple Add-on
Easy installation with simple welding on blocked areas or where you want flow to occur. Because you do not need to drill a hole anywhere, installation is possible while the content (with exceptions) is still in the hopper/container/chute/silo.
For the U-bolt type, which is optimum for bonding to pipes, it can be easily installed with tightening of bolts. In this case, welding is unnecessary, only bolt tightening tool is necessary!

Simple Maintenance Work
Replacing expendable parts on-the-spot is made simple. With only 4 replacement parts, tasks can be completed with just one equipment. Maintenance work on one knocker takes only 10 minutes.

Outstanding durability
Cleared testing of 1 million impacts. (Tested at our internal lab)
Great reduction of damage on expendable parts because it does not continually vibrate as air vibrating type devices. You will be able to use it continuously for 3 years when used twice per minute, 8 hours a day and 365 days straight! (length may vary due to work conditions)
