The HFS VP series of dual-stage rotary vane vacuum pumps are used to obtain a vacuum by pumping gas from a sealed container.
They are extremely useful in refrigeration repair, medical apliances, printing machinery, vacuum packing, gas-analysis, and hot-forming plastics.
See product photos for full specs.

Features:

[Working Temp.]: The 3CFM 2 Stage Vacuum Pump operates in ambient temperature: 5℃~40℃. It is equipped with thermal protection function. If the room temperature is too or the voltage is too high, the product may stop working.

[Oil Anti Flow-Back Design & Environmental Design]: The gas inlet is specially designed to prevent oil form flowing back, preventing the container and hoses from being polluted;
The tank has separating devices at the exhaust port to prevent oil spraying and to reduce pollution.

[Easy start design With Alloy Aluminum Casing]: Motor is made from allow casing which has good heat dissipation to keep the pump running efficiently and for a longer life;
It starts easily even in cold temperatures; Anti-Vibration - An electrometric coupling insert between the motor and module results in an extremely quiet and low vibration running condition.

[Application]: Vacuum Pumps are extremely useful in refrigeration repair, medical appliances, printing machinery, vacuum packing, gas-analysis, and hot-forming plastics.
