🔧 GYZJ 4CFM 1/3HP 5PA Rotary Vane Vacuum Pump: HVAC/Auto AC Air Conditioner Servicing for R12 R22 R134a R410a Systems, Refrigerant Recharging, Wine Degassing, Milking Review

[Key Parameters]: Flow Rate:4 CFM,75 micron. Ultimate Vacuum:5 Pa,1/3HP AC Air Tool Rotary Vane ,Inlet Port: 1/4 Flare,Voltage /Frequency: 110V/60Hz,Oil Capacity:225 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.
