功能

• The ventilation structure allows air to enter and exit freely even with the cap attached.
• Even if a large pressure difference occurs temporarily in the tank due to a sudden temperature rise or backlash of oil, it is safe because it immediately regains equilibrium with the outside air. Suitable for use with pressure boosters and pressure reducers where the amount of oil increases or decreases drastically.
• Since the oil splashing is guarded by the special inclined blade inside, there is no external oil leakage under general operating conditions. In addition, air filters are built into the vents, so there is no need to worry about environmental pollution caused by oil fumes.
