AIR BREATHER
The air breather is equipped with the
capacity to perform two functions
simultaneously-as an air filter and as a
breathing valve.
(1)
Preventing negative pressure inside the
tank
The tank is a pressurized sealed type, so
negative pressure is formed inside the
hydraulic tank when the oil level drops
during operations.
the difference in pressure between the
tank and the outside atmospheric
pressure opens the puppet in the
breather, and air from the outside is let
into the tank or prevent negative pressure.
(2)
Preventing excessive pressure inside
the tank
When the hydraulic cylinder is being used,
the oil level in the hydraulic system
increases and as temperature rises.
the hydraulic pressure rises above the set
pressure, breather is actuated to release
the hydraulic pressure inside the tank.
