Filter bags made of polypropylene can, like all other needle felts, have an antistatic finish.
The antistatic finish can be achieved either by admixture of steel fibers or by a thin grid of stainless steel, which is part of the fiber support. The effectiveness of both solutions is similar, with the grid having a higher regularity resulting in identical conductivity at each point of the material.
The needle felt in this version is ATEX certified and can be used in potentially explosive environments.
Available are also the following versions:
- antistatic + water repellent
- antistatic + oil and water repellent
Applicable in the following industrial sectors:
- electroplating plants
- steel production
- fertilizers production
