Features
- Water Cooling and Forced Oil Supply System
The oil supply to the cylinder is satisfied even under heavy load operation, and more stable exhaust performance can be obtained than with the differential pressure oiling system. - Adoption of hydraulic oil anti-suck system
When the pump is stopped, the backflow of oil from the oil tank to the suction side can be suppressed. - Maintenance-friendly design
A large oil level gauge is used for easy monitoring of the oil condition, and a maintenance cover is provided for cleaning the oil tank and replacing the exhaust valve.
