Compact breather with valve system

This breather cap is designed to balance and control the internal pressure of a mechanism with an oil-bath system. This version is equipped with a valve that, in the event of increased internal pressure, allows excess air and oil vapors to escape into the reservoir. The underhead geometries have been standardized and inspired by DIN 908 regulations. Compact and innovative design, with a new internal sealing pad.

APPLICATIONS: Mechanical applications requiring the use of oil.
