Features and applications

Double-valve breather cap SMW. creates a pressure plenum chamber right above the oil level within given limit conditions in order to avoid any reservoir deformation.

Advantages:

it reduces reservoir air volume intake keeping clean fluid and filter;

it improves suction pump action under working conditions reducing cavitation phenomenon;

it prevents fluid leakage when the system is part of a mobile unit;

it reduces foam in fluid.

Technical Data

Air flow rate for the different executions of breather caps can be obtained from the diagram on the basis of the difference of air pressure inside and outside the reservoir.
