Q: Can this AC vacuum pump kit quickly complete the vacuuming for home air conditioners? Is the flow rate sufficient?
A: The pump features a single-stage rotary vane design with a flow rate of 4 CFM, making it ideal for home air conditioning systems. It achieves a vacuum level of ≤20Pa, suitable for R134a, R22, R410a, and other non-flammable refrigerants.
Q: Can it be used for car AC repairs?
A: Yes. It is compatible with R134a car AC systems. However, be sure to turn off the car engine during the vacuuming process. Due to shorter automotive AC lines, we recommend using quick-connect valves to control the flow. Do not use with systems containing flammable refrigerants like R1234yf.
Q: How loud is the pump? Will it disturb the work environment?
A: The noise level is ≤70dB (comparable to normal conversation). Featuring cast aluminum housing for noise reduction, it operates quieter than similar pumps with iron casings. Fit for use in garages, workshops, or other enclosed spaces.
Q: What does the current protector do?
A: The built-in 4.5A overload protection automatically shuts off power if there is unstable voltage or motor overheating, keeping damage from the motor. Simply press the reset button after maintenance to restart the pump.


You can use R134a, R22, or R410a with the VEVOR AC manifold gauge set and vacuum pump. In vehicle air conditioning, HVAC systems, refrigeration units, and industrial settings, it works with non-flammable refrigerants. Because it works with so many systems, you can repair most air conditioners without needing extra adapters. It gives you a reliable setup for a range of system types and forces.
The design works for both small and big AC maintenance jobs. When you cover more than one type of refrigerant, you do not have to buy as many different tanks and gauges. Professionals and do-it-yourselfers alike can use it, which is a plus. The kit ensures the vacuum works properly and safely. It works well for AC service in homes, cars, and businesses without sacrificing accuracy or dependability.
A 4 CFM single-stage rotary vane vacuum pump with a 1/3 HP high-torque motor is part of the gauge set. The motor's strong and quick suction pulls air and moisture out of AC and refrigeration systems. The shape of the rotary vane keeps the system pressure stable and the airflow steady. With a flow rate of 4 CFM, it quickly removes air and moisture, saving time when doing repairs.
For systems of different sizes, the single-stage pump works reliably and consistently. It works well with both small and large air conditioners. The pump maintains steady vacuum pressure without overheating or losing power. It is a reliable, necessary tool for all AC and refrigeration tasks for multiple repair sessions.
The gauge set and vacuum pump can reach a maximum vacuum of 5 Pa. They can completely remove air and moisture from cooling and heating systems. The high-vacuum system evacuates the entire system, reducing compressor load and improving system performance. The 0.27-qt (260-ml) oil tank in the pump keeps the rotary vane smooth.
The clear oil window makes it easy to see the oil level in the pump. Regular oiling keeps the shaft rotating smoothly and extends its lifespan. Even when things get tough, the pump keeps the vacuum level stable. You can safely empty systems, as you know that the ultimate vacuum at 5 Pa is always reached.
There are three 3.94-foot (1200 mm) hoses in the VEVOR AC manifold gauge set and vacuum pump. They are red, blue, and yellow. For quick and correct links, the color coding makes it easy to tell the difference between the service, low, and high lines. Each hose can withstand working pressures between 800 PSI and 4000 PSI, making them strong enough for tough HVAC and auto jobs.
These hoses connect the vacuum pump, manifold gauges, and the AC system in a safe and leak-free manner. Their strong construction keeps them from breaking, wearing down, or experiencing high-pressure spikes, so the flow of refrigerant stays steady. The 3.94-foot length means technicians can reach all connection points without needing extra cables.
The VEVOR AC manifold gauge set and vacuum pump come with all the tools you need to service AC systems. The package comes with a 4 CFM vacuum pump, a manifold gauge set, three-color lines, and an R410a adapter. Included are R134a quick couplers, a 1/4" SAE-to-1/2" ACME adapter, a leak detector, and an R134a can tap. You do not need any other parts to empty, charge, and test AC systems with this full package.
All the accessories that come with it are designed to fit snugly and work well together. The quick couplers and adapters make it easy to connect to different AC service ports quickly and correctly. The leak detector works well to find system leaks, and the oil that comes with it keeps the pump running smoothly for a long time. The full kit speeds up work, reduces setup time, and makes maintenance easier for HVAC, industrial, and automotive uses.
The gauge set and vacuum pump come with a strong carry bag that keeps all of the parts safe. It has organized spaces for the vacuum pump, manifold gauge set, lines, and other parts. The bag keeps tools safe from dust, water, and accidental damage. No scratches or lost items because each one fits tightly. It makes it easy to move the whole kit from one job spot to another or store it neatly in a workshop.
With its durable, long-lasting material, the carry bag can handle frequent use and tough conditions. It is not too heavy, but it is strong enough to hold the whole kit without breaking or sagging. The carry bag makes the kit easier to move around and keeps all the tools close at hand.
