Information
Breather plugs GN 552.1 with sealing disc vents the tank after a lower pressure of 10 or 100 mbar respectively is reached.
The sealing disc prevents the contamination of the oil from the outside (dust) and an air filter is not required. In addition this ensures that no oil can spill to the outside, neither by excessive agitation in the tank nor during transport.
The disc is TEFLON coated which prevents it from sticking to the O-ring and ensures the maintenance of the opening pressure.
Breather plugs GN 552.1 with opening pressures other than 10 or 100 mbar on request.
