A high flow-rate of extremely abrasive solids is one area of use of the AIRDUC^? PUR 355 INLINER-AS that NORRES is now supplying in an antistatic version. The unchanging permanent conductivity without the migrating antistatic agent of the hose makes it suitable for use in glass factories, cement plants and quarries. The AIRDUC^? PUR 355 INLINER-AS is smooth on the inside and extremely abrasion-resistant due to the inliner reinforcement.
