The Features for Double Stage Vacuum Pump

Introduction

Two stage vacuum pump has two rotors and vanes. The first stage generates vacuum and the second stage cleans the system, so as to lead to a deeper ultimate vacuum level. So that two stage pumps can produce a deeper vacuum than single stage pumps.

There is the technical data for the two 2 stage vacuum pumps in the pictures. When making your choice, you should consider what you want to achieve. If your goal is faster evacuation, cleaner process, and quieter operation, then the answer is a two stage pump.

Features:

There are two ports on our vacuum pump. And an additional female x barb adapter is available. 

To avoid chamber contamination, the refrigerant vacuum pump can prevent the oil from flowing back and polluting its container and tubes. Oil fill port makes oil adding simpler since the port is accessible from the front or either side.

This vacuum pump comes with an oil viewing window so that you can easily monitor oil levels and quality, avoid oil deficiency. The oil drain valve at the bottom of the oil reservoir ensures faster and more complete draining.

Our vacuum pump tool can cool itself and avoid burning out when something is stuck. 

Ergonomic grip handle is superior comfort and portability. The automotive vacuum pump is suitable for household air conditioning, vacuum packaging, refrigerator vacuum, industry, and etc.

Advantages

The double stage vacuum pump has a higher vacuum level and a higher sealing property. 

With high efficiency and low noise. 

Internal intake check valve prevents oil backup or oil suck back into the system during a power failure or when stop pumping. 

Intake filter screen keeps damaging particles from entering the pump. An oil fog cleaner is set inside to prevent the oil fog exhausting to the atmosphere. 

The large starting torque guarantees to start normally under cold winter's extreme low temperature.

Oil drain plug positioned at bottom of the oil tank, to achieve a faster and complete draining. 

The cooling fan can extend use life, and achieve thermal protection.

Exhaust port with exhaust cap, direct drive motor allows easy starting and is maintenance free. 

This vacuum pump is suitable for all refrigerants.
