A good filtering and condensate removal reduce considerably the costs of the devices’ maintenance and missed production and allow to maintain an invariable final product’s quality. The value of duplex filters is the possibility to carry out maintenance without interrupting the work process: while one cartridge is working, the other doesn’t filter, allowing manual operator intervention. The filters we design and produce are suitable for installations on pressured lines and are able to work with operating temperatures up to 120°C. On demand we supply filters for temperatures higher than 200°C.
