Elesa® original design technopolymer plastic filler breathers.
Resistant to solvents, oils, grease and other chemical agents.
10 mb: Valve opens when pressure exceeds 0.010 bar.
100 mb: Valve opens when pressure exceeds 0.100 bar.
Used when air exceeding a certain pressure value must be expelled, for example, on speed reducers, variators and compressors. Sealing disc prevents against dust and oil loss.
In addition this design ensures that no oil can spill to the outside, neither by excessive agitation in the tank nor during transport.
Maximum continuous working temperature: 212°F (100°C).
