The Renewed EXEN Air Knocker

26 Mar 2024  |
The renewed EXEN air knocker adopts a design and material that minimizes wear of each part during long-term use, and has a structure that can suppress performance deterioration even during long-term use.

By changing the material of the cylinder to aluminum die-casting, the weight of the knocker body is reduced, and the wear resistance of the cylinder is guaranteed by the inner resin sleeve.

In addition, the tank part has been downsized while ensuring its capacity, achieving a weight reduction of up to 28.5%.

The redesigned EXEN air knocker improves wear resistance to minimize performance degradation and prevent powder clogging for extended periods of time.

What is the EXEN Air Knocker?

The EXEN Air Knocker is an auxiliary device that facilitates the handling of powder and bulk materials. EXEN Air Knocker can support storage, transportation, and supply at various manufacturing sites that handle powder and bulk materials, such as grain or feed silos, flour mills, and cement factories.

In the storage, transportation and supply of powder and bulk, problems such as blockage of powder, bulk-called bridges and rat holes and adhesion to the wall surface frequently occur.

Using air knockers is one way to solve these problems. The hammer effect caused by the impact generated by compressed air eliminates the blockage and adhesion of powder and bulk.

Since EXEN air knocker is powered by compressed air, impact force can be greatly changed by adjusting the supplied ai pressure.

Therefore, even if the impact force is insufficient or excessive after the installation, it is possible to obtain the impact force suitable for the site without changing the model.

With the relay piping that connects each knocker with a tube, multiple knockers can be controlled simultaneously with one control system.

For facilities that requires a large number of knockers, the relay piping reduces the number of operation panels used, reducing equipment costs.

Furthermore, the dedicated operation panel “Air Operation Controller AOC-1B” does not require a power supply or electric timer; the operation interval of the air knocker can be controlled simply by supplying air.

The RKV-type knocker is available in seven sizes to accommodate a wide variety of applications.

The RKD-type knocker is available for equipment that moves or rotates the part where the impact of the knocker is applied, or for resin hoppers that cannot weld metal equipment. Secure the knocker to another pedestal and place it in a position where its piston hits the object. The RKD-type knocker is available in 6 sizes.

A stainless steel-type knocker suitable for rechargeable battery, food, pharmaceutical and chemical industries is also available. The model of the air knocker is selected according to the thickness and dimensions of the application and the characteristics of its contents.

EXEN provides solutions that suit the customer based on our extensive knowledge of powder blockage elimination, cultivated over many years. Please feel free to contact us if you have any problems with powder flow, clogging, and or adhesion.
