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 the excess air and oil vapors to escape into the reservoir. The outer cap protects the device from foreign objects that could cause damage to equipment and machinery.

APPLICATIONS: Mechanical applications requiring the use of oil.
