Breather cap for breeze (ventilation) structures.
[Features]
· Steel air filter is mesh shaped.
· Polyurethane air filter is sponge shaped.
· Breeze (ventilation) structure: Since it is a structure built for ventilation, even if a cap is attached, air can enter and leave freely.
· Even if a large pressure difference temporarily occurs in the tank due to a sudden temperature increase or oil backlash, safety is restored as soon as equilibrium is regained with the outside air.
· Optimal when using pressure boosters and decompressors where the oil amount drastically increases and decreases.
· Splash guard (oil splashing and leakage prevention): Features a special sloped wing on the inside that guards against splashing oil, preventing external leakage of oil under general use conditions.
· Additionally, an air filter is built into the ventilation hole so there is no worry of environmental pollution caused by oil fumes.
[Applications]
· Pressure boosters and decompressors where the oil amount drastically increases and decreases.

Valve caps with 2 types of operating pressure: 10 hPa and 100 hPa.

· 2 operating pressures are available.
· Exhaust cap.
· Does not intake external air.
· Operating temperature: -30°C to +120°C.
