Utilizing the BF Series Breather with Duo Valve is more effective than conventional breathers by eliminating the problem of oil sloshing out of the reservoir tank (environmental and cleanliness concerns) and conserving the costly hydraulic fluid.

The breather utilizes two springs operating on poppets. These specially designed check valves allow the tank to breathe in both directions without allowing oil to escape.
