1. Pneumatic drive controlled by a solenoid valve. Output pressure is controlled by the input air pressure.

2. Intermittent oil delivery without electrical power or a control box; simple, durable construction.

3. Recommended 4-8 kgf/cm2air pressure, and set the solenoid valve ON/OFF time to at least 5 seconds for normal oil discharge.

4. Includes a pressure gauge for checking operating pressure.

5. Includes a float switch for oil level detection and automatic signaling.

6. An oil-volume adjustment knob allows output to be adjusted as needed.

7. An optional 1 kgf/cm2pressure switch can be installed at the oil outlet to detect damaged oil lines.

8. Optional magnetic return-oil strainers and tank baffles filter lubricating oil returning to the tank. (a) Magnetic return-oil strainers can be fitted to tank models of 3L and above. (b) Tank baffles can be fitted to 3L and 4L resin tanks and 8L sheet-metal tanks.

9. Refer to the float / float switch specifications for contact information.

10. Refer to the diaphragm pressure switch specifications for contact information.
