Our air knocker can provide results on any necessary work type and is especially effective against fine powders and sticky or clinging materials in the hopper, chute and pipes. Knocker will successfully discharge the work even if the content is made of fine particles or those with sticky and moisture materials which is impossible to discharge with using pneumatic vibrators.
100% made in Japan.
*We  are currently looking for distributors in each EU coutires who can promote and expand our air knocker products together.
If you are inerested in becoming our distributor, we are pleased to have a meeting  with you at our booth during POWTECH SHOW. 
Easy to adjust impact force  only with adjusting a pneumatic pressure.
(0.3 – 0.7 MPa) can increase and decrease knocker impact force.
Depends on the powder condition, it can allow to adjust an impact force and then can provide the best impact force for various type of conditions

Simple maintenance                                 
  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.

Stainless steel and sanitary spec knocker available as our standard model

(In-house comparison)

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 without any maintenance.
