VEVOR AC Vacuum Pump Manifold Gauge Set 4.8 CFM 5PA HVAC Vacuum Pump With Box

4.8 CFM Single-Stage HVAC Vacuum Pump and Gauges for Fast Air Removal

This HVAC vacuum pump and gauges set features a single-stage pump that delivers 4.8 CFM of free air flow, allowing you to quickly and effectively clear AC and refrigerator lines. You can clear moisture and non-condensable gases from the system before charging it, because the 1440 RPM speed keeps the airflow steady. In the long run, a clean evacuation lowers the chance of ice buildup, compressor stress, and less effective cooling.

The heavy-duty aluminum used to make the pump body prevents rust and performs well even after many uses. The unit remains stable while working because the base is shockproof. This feature lowers shaking and noise. There is no need to worry about this pump breaking down when you are working on commercial refrigeration equipment or a home AC unit. Because it is small, it is also easy to move from job site to job site or store in a service vehicle.

1/3 HP Copper Motor for Continuous, Reliable Operation

An AC230V, 50Hz copper motor, which is the heart of this vacuum pump, does its work. For longer duty cycles, the motor can run continuously with copper windings because copper dissipates heat and uses electricity more efficiently than other materials.

This power output matches the pump's 4.8 CFM discharge, so the system is balanced and does not overwork the motor. At a maximum vacuum level of 5Pa, the pump effectively reaches a deep vacuum, which is necessary to remove trapped air and moisture from refrigerator lines before they can cause long-term damage. This level of vacuum performance is what you would expect from a professional HVAC vacuum pump and gauges, making it suitable for both technicians and serious do-it-yourselfers.

Dual-Pressure Manifold HVAC Vacuum Pump and Gauges for Accurate System Readings

You can check both the high- and low-side pressures simultaneously with the dual-pressure gauges in the manifold gauge set that comes with this kit. You can see how well the system is working during charging, recovery, or diagnosis because the high-pressure hose reads 0–800 psi and the low-pressure hose reads 0–500 psi. Reading both sides at the same time saves time and reduces the likelihood that you will miss a problem as it arises.

HVAC vacuum pumps and gauges need to provide accurate pressure readings because incorrect charging can cause the cooling system to fail or strain the compressor. The readouts on these gauges are clear and accurate, so you can make choices right away, whether you are adding more refrigerant or figuring out what is wrong with the system. The large dial faces are easy to read even in a garage or on a roof in low light, making it easier for workers out in the field.

Oversized Sight-Glass for Clear Refrigerant Flow Monitoring

The manifold gauge unit has a large sight glass that lets you see the refrigerant flow as it passes through the system. This feature makes it easier to detect bubbles, contamination, or changes in flow that could indicate a problem before it gets worse. Seeing these signs early on can keep a small problem from getting worse and costing a lot to fix.

When used with the two pressure gauges, the sight glass gives you even more information to help with your repair. You do not have to rely on pressure readings alone; you can also check whether the refrigerant is flowing properly. This feature helps you quickly identify problems and avoid callbacks or additional service trips. This mix of numerical and visual feedback gives techs more confidence as they try to figure out why a system is acting strangely.

Leak-Proof 45-Degree Brass Fittings for Secure Hose Connections

This set comes with four high-quality rubber lines, color-coded to make them easy to find during setup. One end of the metal fittings is angled 45 degrees, and the other end is straight. This feature makes a tight, leak-proof seal at every connection point. It is also easier to run hoses around tight areas without kinking them because of the two angles.

With 1/4" and 3/8" intake fittings, you can connect the lines to a variety of systems, so you are not limited to just one. These hoses can handle tough conditions thanks to their high working pressure ratings. They work well on car AC systems, home units, and commercial refrigeration equipment. As you coil and uncoil them between jobs, the long-lasting rubber design helps prevent cracking and wear.

Built-In Thermal Protection HVAC Vacuum Pump for Extended Motor Life

This vacuum pump has a built-in oil viewing window and can hold 250 ml of oil. This feature makes it easy to check the oil level and keep the unit from running without enough lubrication. With the viewing window, you will never have to guess the oil level, which is important for keeping the vacuum working well and preventing internal parts from wearing out too quickly.

The pump also has built-in thermal protection that stops it from operating if the internal temperature gets too high. This safety feature keeps the motor from overheating and makes the tool last longer. And because it is self-cooling, this HVAC vacuum pump and gauges set can handle heavy use in home, car, and business settings without overheating. This feature makes it a reliable tool you can use from one job to the next.
