HVAC 2 Stage Vacuum Pump with 6.0 CFM Flow Rate for Fast HVAC System Evacuation 

With a flow rate of 6.0 CFM (170 liters per minute), this HVAC 2 stage vacuum pump swiftly removes air from refrigeration lines, allowing you to work more and spend less time waiting. This output is powered by a 1/2 HP copper motor that operates consistently during extended evacuation cycles, making it suitable for both routine maintenance and more complex system tasks. When working on systems with longer line sets or larger refrigerant volumes, a high flow rate is especially important because slower pumps can cause technicians to wait significantly longer than necessary. 

The high flow rate greatly reduces the time required to service commercial refrigeration equipment, automobile air conditioning systems, and home air conditioning systems. The device's compact, ergonomic design allows you to transport it between job sites without additional strain, even during back-to-back service calls, and its heavy-duty aluminum alloy shell permits continuous operation without overheating. The robust copper motor is designed to deliver steady, consistent performance every time, even under heavy use.

5Pa Ultimate Vacuum for Thorough Moisture and Air Removal

Before recharging, this pump eliminates virtually all residual moisture, air, and non-condensable gases from refrigeration lines thanks to its deep ultimate vacuum rating of 5Pa (0.05 mbar). The precision evacuation this HVAC 2 stage vacuum pump is designed to provide is reflected in its factory micron rating of 15, which helps protect compressors and other system components from long-term damage. Because residual humidity is more likely to have entered the lines during disassembly, this degree of vacuum is especially crucial for systems that have been opened for repair.

Since stored moisture can freeze, damage internal components, or eventually lower refrigerant efficiency, incomplete evacuation is one of the main reasons HVAC systems fail. By achieving this degree of vacuum depth, the pump reduces the likelihood of callbacks. It helps systems function effectively from the first start-up cycle onwards by assuring operators that lines are properly prepared before charging. When working on systems that must pass inspections, ensuring operators meet warranty requirements for correct installation is extremely helpful.

No-Flow-Back Design to Prevent Oil Contamination

The no-flow-back design of this refrigerant vacuum pump prevents oil from flowing backward into the chamber, which prevents contamination of the tubing and oil reservoir. This reduces residue buildup that could otherwise impair pump efficiency on long-term jobs, keeping the pump's internal parts cleaner over time and helping maintain consistent vacuum performance across repeated applications. Over the pump's lifetime, cleaner interior parts also result in fewer unplanned repairs.

An oil fill port that is accessible from the front or either side of the unit makes adding oil simple and eliminates the need to maneuver around awkward angles or narrow clearances. Whether the pump is positioned on a workbench for planned maintenance, mounted in a service van, or installed on a rooftop unit, this adaptable access point expedites routine maintenance. When front clearance is limited, the side-access option is especially useful for technicians working in small mechanical rooms.

Viewable Oil Window with Bottom Drain Valve for Easy Maintenance

You can quickly check oil levels and clarity with an oil sight glass, allowing you to identify low oil levels or degraded oil quality before they impact pump operation. For technicians who rely on reliable performance in daily use, staying ahead of oil changes helps protect the vacuum pump's internal seals and prolong its operating life. Before beginning any task, a brief visual inspection helps prevent operating the pump with inadequate lubrication.

When it is time to drain, the oil drain valve at the bottom of the reservoir allows you to remove old oil more quickly and thoroughly than by tipping the unit or manually siphoning it. The pump's 250 cc oil capacity makes it easy to schedule maintenance intervals, minimizing downtime between service calls and ensuring the pump is ready for the next task. Additionally, this simple drain procedure lessens the mess that usually results from changing the oil in a vacuum pump.

Built-In Thermal Protection for Reliable HVAC 2 Stage Vacuum Pump Operation

This pump's clever radiator system reduces the risk of burnout if the motor encounters resistance or gets stuck mid-cycle. An additional line of defense is provided by built-in thermal protection, which automatically prevents the motor from overheating during prolonged operation, especially on warmer days or during consecutive evacuation tasks. No matter how busy the schedule gets, these protections work together to keep the motor operating within a safe range.

The pump can handle rigorous tasks without compromising dependability or shortening its service life, thanks to a combination of cooling and thermal safeguards. This HVAC 2 stage vacuum pump's base is made of composite rubber, which reduces vibration and increases stability during use, further safeguarding internal components and extending the pump's lifespan. During longer evacuations, a sturdy foundation also prevents the unit from shifting or vibrating across a workbench.

Dual SAE Inlet Ports for Flexible HVAC and Refrigeration Use

This pump's 1/4" SAE and 1/2" SAE inlet ports make it simple to connect to conventional HVAC and refrigeration hoses without additional adapters in most installations, saving technicians time and reducing the number of fittings they must carry. It is more comfortable and portable thanks to the ergonomic handle, which makes it easier to move between vehicles, rooftops, or indoor units during a hectic workday without straining your wrist or grip.

This pump is suitable for home air conditioning, car air conditioning maintenance, vacuum packaging, refrigerator repair, and light industrial applications in a variety of climates. Its operational temperature range is -5°C to 60°C. Whether working indoors, in a garage, or on a rooftop unit, a 150cm power connection gives professionals more flexibility to place the unit close to the job site without requiring an extension cord.
