Material: PTFE Basic body suitable for R 3 / 4 ″ internal thread, with GL 32 cap thread, with PTFE/silicone gasket and replaceable filter membrane (pore size 2.5 μm) made of PTFE, screw cap made of PPS. High chemical resistance, the medium only comes into contact with PTFE. Membrane outer Ø 29 mm, membrane thickness approx. 0.2 mm. Temperature stability from -20 °C to +230 °C, autoclavable. Pressure compensation from 0.1 bar differential pressure. Maximum flow rate: · At 0.5 bar differential pressure: 80 l/h · At 1.0 bar differential pressure: 320 l/h Application For pressure compensation during liquid removal or when filling containers. The integrated filter membrane prevents contamination of the medium with dust or dirt particles. Barrel aeration
