Since 1915 EXEN Corporation (Tokyo, Japan) has been solving material flow problems with our original products is called AIR K ... NOCKER (impactor). 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. Features ･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 Perfect for food & dairy, pharmaceutical, chemical and medicine products where corrosion is unacceptable. Also sanitary models with the ferrule clamp spec are available. ・Minimal consumption of air. Reduction of electricity in your factory! Air consumption rate for one impact of EXEN Air Knocker is dramatically lower than that of existing pneumatic ball / piston/ turbine typed vibrator. 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. *We are currently looking for distributors in each EU coutires who can promote and expand our air knocker products together. read more
