Rotary Vane Vacuum Pump: Our 4CFM rotary vane air conditioner evacuation vacuum pump is designed with high quality aluminum alloy casing for good ventilation and heat dissipation, and the motor and pump are designed as a whole, which is more compact, light and reasonable, with 1/3HP motor power and 5pa ultimate pressure.
Anti-returning Oil Design: The inlet channel is specially designed to prevent the pump oil from flowing back and polluting the pumped container and pipeline after stopping the pump,With 1/4"Inlet Port, the maximum capacity of the pump is 225ML, and we will offer a bottle of 220ml vacuum pump oil as a test.
All Copper Motor: All-copper movement is better than aluminum wire, the vacuum pump has a longer service life and faster running speed. Strong copper motor makes the machine vacuum, to ensure stable operation of the machine, energy saving and power saving
Large Oil Window Design: large oil window, the minimum level of the maximum level of oil at a glance to prevent the lack of oil, while you can pay attention to the refueling situation at all times. The machine is suitable for refrigeration maintenance, printing machinery, thermoplastic molding, vacuum packaging, medical equipment, etc.
Forced Cooling: The wind page at the end of the machine intervenes to reduce the heat generated when the machine is running, ensuring the smooth operation of the machine and making the machine last longer
