SFW-BA+a

Breather caps with double valve

Features

The use of SFW-BA+a breather caps which create a pressure plenum chamber right above the oil level within tested limit conditions, in order to avoid any reservoir deformation, offers the following advantages:

• it reduces reservoir air volume intake keeping clean oil and filter;

• it improves suction pump action during 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.

 

Special executions on request

• Black colour cover.

• Overpressure valve set at 0.700 bar.
