More Details
Features & Details
  • Heavy Duty Vacuum Pump: FAD: 3 CFM, Single Stage; Power: 1/4 HP; Ultimate Vacuum: 5PA. Our HVAC vacuum pump comprises heavy-duty aluminum alloy with durability and sturdiness. The strong copper motor provides continuous power, and a shock-proof base supports the stable operation.
  • Precise Manifold Gauges: The refrigeration kit has manifold gauges. The dual-pressure gauges are high quality, allowing you to know the actual working pressures anytime to facilitate easy maintenance systems. Besides, the oversized sight-glass is designed for easy viewing of the refrigerant flow.
  • Multifunctional Hoses: The three hoses are made of premium rubber with different colors. Their brass fittings are 45 degrees on one hand and straight on the other, providing a leak-proof seal. Characterized by high working pressure and various connection sizes, the hoses can satisfy your different requirements.
  • Easy Monitoring & Cooling: With an oil viewing window, this AC vacuum pump can easily monitor oil levels to avoid oil deficiency. Our vacuum pump tool can cool itself and prevent itself from burning out. The built-in thermal protection prevents the machine from burning and extends the machine’s life.
  • Wide Application: The vacuum pump is widely used for commercial and household applications, suitable for cleaning a household air conditioner, automobile maintenance, vacuum packaging, refrigerator vacuum, industry, medical equipment, automobile maintenance industry, automatic control, printing machinery, packaging machinery, food preservation, aquaculture, water purification treatment, analytical instruments, beauty care, advertising production, equipment maintenance, bio-pharmaceutical, communications electronics, petrochemical, plateau oxygen, environment detection system, etc., At the same time, it can be used as a pre-pump for all kinds of high vacuum equipment etc.
  • Operating instructions:
  • 1. Check the oil level, and it is appropriate to fill oil to the center of the oil mark when the pump is stopped. Too low can not play the role of oil seal on the exhaust valve, affect the vacuum degree is too high, may cause the air starting oil injection. During operation, the oil level is elevated, which is a normal phenomenon. The oil is clean vacuum pump oil of specified grade and added through the refueling hole. After refueling, screw up the plug. The oil should be filtered to avoid sundries entering and blocking the oil hole.
  • 2. The pump can be started at one time through the atmosphere or any vacuum degree. If the pump port is connected with the solenoid valve, it should act at the same time as the pump.
  • 3. When the ambient temperature is too high, the temperature of the oil will rise, the viscosity will decrease, the saturated vapor pressure will increase, and the ultimate vacuum will decrease, especially the total pressure measured by the thermocouple meter. The ultimate vacuum can be improved by strengthening ventilation and heat dissipation or by improving the performance of pump oil.
  • 4. Check the ultimate vacuum of the pump with the compression mercury vacuum gauge. If the gauge is fully pre-pumped and verified, the pump temperature is stable, and the pump port is directly connected with the gauge, and the pump will reach the ultimate vacuum within 30 minutes of operation. The values measured by the total pressure gauge are related to the pump oil and vacuum gauge and regulatory errors, sometimes even large, and are only for reference.
  • 5. If the relative temperature is high, or the pumped gas contains more condensable steam, it is advisable to open the gas valve after the pumped container is connected, and close the gas valve after 20-40 minutes of operation. Before stopping the pump, the valve can be opened for 30 minutes without load to prolong the life of the pump oil.
  • 6. Oil selection: the viscosity of the pump oil affects the starting power and the ultimate vacuum of the pump. High viscosity is beneficial to the vacuum degree, and the starting power is larger. The saturated vapor pressure of the oil at the pump temperature will affect the ultimate total pressure of the pump, the lower the better. High speed vacuum pump oil and 3 well diffusion pump oil have higher viscosity and lower saturated vapor pressure than No. 1 vacuum pump oil, but the price of No. 3 diffusion pump oil is higher. The specific choice of what oil, according to the above introduction combined with specific use requirements to choose.
  • (1) if the vacuum degree is not high, and the pollution of oil frequent replacement, vacuum pump oil supply difficulties, can be replaced by No. 50 mechanical oil.
  • (2) if the ambient temperature is low, the starting is difficult, the limit vacuum requirement is not high, the viscosity is lower than the real house pump oil or mechanical oil can be used

    The gauge set and vacuum pump work perfectly. I had my A/C system fully evacuated and charged in less than two hours and most of that time was spent making sure I didn’t have any leaks. For those referencing the kit not coming with a freon can adapter, kit: https://www.amazon.com/gp/product/B07D18WVFD/ref=ppx_yo_dt_b_asin_title_o01_s00?ie=UTF8&psc=1 works well with this gauge set.

    I needed a vacuum system that would not break the bank. After all, chances were great that I would not be needing to use it again anytime soon once I successfully completed the repair. The problem: most manufacturers were asking way to much for its system. Then I came across this complete kit, it did the job well and it will continue to do a great job if I have need for it down the road. I just added it to my tool collection. I paid for itself and I get to keep it in addition to the hundreds of dollars savings because I did the repairs myself.

    This machine works really well. It took a minute to figure out how to put the oil in though. The instructions were somewhat helpful. This was purchased to aid in automobile Air Conditioning repairs. And it has worked flawlessly.

    Hi. Works great. Initially was skeptical about filling oil in exhaust port because the exhaust port is a oil filler port. It took a bottle and a quarter before oil level increase with oil provided in box. Gets a bit hot on long vacuum. But pulls a deep vacuum in few minutes. Pump only weights 17lb or 7.8kg and shipping weight is 22lb. Connection to manifold gauge or micron gauge with hose was not a problem. sit well and does not move during operation.

    Disappointed the exhaust filter arrived broken, shipped with oil in the pump and was apparently turned upside down, oil all over the inside of the box and owners manual.

    This is a good product up until I realized the adapter in this package did NOT work. But there is a way to do it.WARNING!! DO IT AT YOUR OWN RISK!!Here is how you refill the refrigerant without an adapter1. This product2. R134a refill kit (comes with hose)When you vacuumed AC (Low side, -30PSI), just unplug it. Then plug the charging hose which comes with the R134a can (like Arctic Freeze with the hose) right on the LOW side. Start refilling until the gauge stays in the blue zone, then start the engine and set the AC to MAX. You will hear AC clutch engaging (if you have no issues such as leaks, electrical problems, etc), then fill more refrigerant if the gauge is not in the blue zone.

    I was suspect to buying this at the price it is at. I work in the HVAC industry and we have to use these all the time to get moister and non-condensable material out of the refidgerant line. This works just as good as a vacuum pump that is 5 times as expensive. Easy to clean and drain of oil and easy to fill back up. I highly recommend this to anyone.

    Overall this is a nice kit for the DIYer. The instructions are very poor and confusing so expect to look elsewhere to understand how a 4 valve manifold operates and should be hooked up (they got it wrong). Having the 4th valve is nice because it’s easy to purge air from the line connected to the refrigerant before charging the system. Except for the leak detector, the hardware in this kit works good. The detector stopped working after a few uses and it just constantly beeps now. There are better methods for leak detecting (dye; pressurize system with air and use soap). The gauges were not set to zero but they are adjustable. The included case that holds everything is a nice touch.
