3.5 CFM Rotary Vane Vacuum Pump for HVAC/AC Refrigerant Recharging, Single Stage

  
[Key Parameter] : Flow Rate: 3.5 CFM, Ultimate Vacuum:5 pa, 75 microns, 1/4HP AC air tool rotary vane vacuum pump, Inlet Port: 1/4 Flare, Voltage /Frequency: 110V/60Hz, Oil Capacity:200 ml, Full body pure aluminum, good thermal conductivity, stronger and more durable. Perfect for maintaining R134, R134A, R12, R22, R22A, R404A, R407C, R502 and R410A systems. [Professional Refrigeration Maintenance Equipment] : Our vacuum pump adopts a direct-connected motor structure, which makes the structure more compact, smaller in size, lighter in weight and easy to carry. Suit for those who are looking to self diagnose or recharging AC systems; It maintains air conditioning systems by efficient removing moisture before refilling the refrigerant. [Stable Operation] : The built-in motor is cast by a full copper movement, which is better than aluminum wire and has a longer service life, also running faster. Strong copper motor makes the vacuum pump operate stably, Greatly increase the vacuuming speed. [Large Oil Window Design] : The vacuum pump adopts a large oil window design, and the minimum and maximum oil levels in the pump can be seen at a glance, preventing the machine from running out of oil during operation, and can always pay attention to the refueling situation. Besides, The trap contains a filter mesh, which can moderately filter oil mist and reduce pollution. [Strong Heat Dissipation, Anti-reflux] : The vacuum pump adopts a strong heat dissipation design, and the air flap at the rear of the boot is intervened to force cooling.

At the same time, the noise generated during the operation of the machine is well reduced. The air inlet channel is specially designed to prevent the pump oil from flowing back and polluting the pumped container and pipeline after the pump is stopped. The Rotary vane vacuum pump base was made of composite rubber material, shock absorption and seismic resistance, which can extend machine life. Four rubber bottoms increase product stability, anti-skid rubber feet to ensure mini movement.

The refrigerant vacuum pump is Produced for prevent oil from flowing back and polluting its container and tubes. The Solenoid valve can cut off the power supply failure automatically which can effectively prevent gas reflux.

This 3.5cfm 1/4HP vacuum pump comes equipped with an oil viewing window which can easily monitor oil levels and quality, and prevent from oil deficiency. Oil Drain valve positioned at the bottom of the oil reservoir and angled for faster, more complete draining. The vacuum has self-protection function, Which can protect itself and prevent it burning out when something is stuck. Built-in big volume cooling fan for extended use and overheat self- recovery fuse. Format heat dissipation window design, fast heat dissipation, effective protection of machine performance.

The pump is easy to carry which equipped with a portable handle. Handle design comes with the case coated with antiskid rubber. The vacuum pump suit for wide range of applications: suitable for household air conditioning, automobile maintenance, vacuum packaging, refrigerator vacuum, Industry, etc. 3.5cfm 1/4HP Vacuum Pump. High torque design for easy start-up and efficient operation; It has lightweight cast aluminum construction and is thermally protected to make it durable for longevity.
