It is completely plastic version of centrifugal radial ventilator made from polypropylene. It has great mechanical, temperature characteristics and chemical resistance. Construction itself is made from acid resistanta rustless steel W.Nr. 1.4571 with built-in asynchronous SIEMENS electromotor. All parts connected with fluid are made from polypropylene.
Centrifuga3 ventilator has on side bulit-in sucking pipe on which we can fix the sucking pipelines with standard dimensions (FI 110,FI 125 ,FI 160, FI 200, FI 250 … )
The pressure part of ventilator is separated with slide acid resistant washer, so that agressive steam can not get to electromotor.
