Robinair's CoolTech 2-stage rotary vane design vacuum pump features the power and capacity needed for a wide range of service applications as well as robust construction for a long service life. Powerful 13 HP, 115V220-250V - 6050Hz thermally protected motor, 94 liters per minute free air displacement, and factory rated to 20 microns for a fast, thorough evacuation. Offset rotary vanes build powerful compression within the pumping chamber - reducing pressure and vaporizing moisture durable molded polycarbonate base improves pump balance and minimizes vibration. Iso-Valve isolates pump from system with just a quarter turn Gas Ballast design mixes moisture laden air passing through pump with relatively dry air so compression doesn't cause condensation. 14 inch male flare and 12 inch ACME inlet fittings, easy to read sight glass, easy access oil fill port, and angled oil drain valve for faster, more complete draining of the reservoir.

Key Parameters Flow Rate5 CFM,15 micron. Ultimate Vacuum0.3 Pa,12HP AC Air Tool Rotary Vane ,Inlet Port 14 38 Flare,Voltage Frequency 110V60Hz,Oil Capacity330 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..
