Instant and Powerful Removal of Material Stuck to Micro-Powder Hoppers

Removal of stubborn ultra-micro powder from hoppers can be a big problem. Uras Techno has the solution. Just use a single powerful strike from our compact magnetic impactor.

The electromagnetic impactor compresses a spring with electromagnet. Instantaneously releasing the spring produces a hammering device that applies a strong impact to the installation surface.

Air-driven single impactors are also available.

Features
  1. Electrical models or air models can be selected according to the installation location.
  2. Easy to control the impact force.
  3. Long service life with simple construction.
