Support air fans 

for double membrane gas storage tanks for constant pressure generation in the interspace of the membrane of the gas storage tank independent of gas filling and gas withdrawal. This constant pressure without any drops in pressure can only be achieved with a very flat characteristic curve of the fan.

Power range 

• Pressure: 5 – 100 mbar
• Volume : 100 m3/h – 10.000 m3/h
• Available in equipment category Atex II 2G T1 (Zone 1)
• Flat characteristic curve for constant pressure
