VIVOHOME 3/4 HP 7.2CFM 2 Stage AC Vacuum Pump and 4 Way

The VIVOHOME 3/4 HP 7.2 CFM 2-Stage AC Vacuum Pump Kit provides a complete setup for servicing automotive air conditioning and home mini-split systems. Designed for both DIY enthusiasts and professional HVAC technicians, it solves the problem of moisture and non-condensables in refrigeration lines, preventing internal ice buildup and component wear. It delivers a fast evacuation down to 15 microns using a high-speed copper motor operating at 2880 RPM.

In practical use, the pump runs cleanly and quietly at 65 dB or less, using dual exhaust filters to keep oil mist out of your working area. The unit features standard 1/4 inch SAE and 1/2 inch ACME inlet ports, making it ready to work with common refrigerants including R134a, R410A, R22, R12, and R502. The included manifold set features a shock-resistant gauge reading up to 800 PSI, while the 7-level leak detector helps locate micro-leaks prior to charging.

Durability is supported by a solid aluminum housing, an iron base, and vibration-dampening rubber feet. A built-in cooling fan maintains safe operating temperatures during standard 40-50 minute duty cycles. The kit comes complete with four color-coded hoses, two bottles of vacuum oil, quick couplers, can taps for both self-sealing and piercing cans, and multiple adapter fittings.

When planning your work, keep in mind that this unit is strictly rated for standard refrigerants and cannot be used on A2L or A2 systems. Users must also remember to turn the quick couplers to the closed position before attaching them, as they arrive shipped in the open position. Continuous run times should stay within the recommended 40-50 minute cycle window to allow proper cooling.

Verdict: This all-in-one vacuum and manifold kit is an excellent choice for DIYers recharging vehicle A/C systems or technicians installing standard mini-splits. It provides all the necessary diagnostic tools and evacuation power in one package.

A great fit if you:

• Need a complete evacuation and diagnostic kit for R134a automotive A/C recharges.
• Install or service home mini-split systems using R410A or R22 refrigerants.
• Want an all-inclusive set with gauges, hoses, leak detector, and vacuum oil included.
• Prefer a quiet pump with built-in oil mist filtration and anti-backflow protection.

Consider something else if you:

• Work with newer A2L or A2 category refrigerants.
• Require continuous, uninterrupted vacuum cycles lasting longer than 50 minutes.

Which refrigerants can this vacuum pump kit be used with?
It is compatible with R134a, R410A, R22, R12, and R502. It is not suitable for use with A2L or A2 refrigerants.

What accessories come included in the box?
The kit includes the 7.2 CFM dual-stage pump, 2 bottles of vacuum oil, a manifold gauge set, a 7-level leak detector, 4 color-coded hoses, 2 R134a quick couplers, 3 adapters, and 2 can taps for self-sealing and piercing cans.

Why is there a note about the quick couplers?
The quick couplers ship in the open position from the factory, so you must turn them to the closed position before connecting them to your system.

How long can the pump run continuously?
The pump is designed with a built-in cooling fan to operate within standard duty cycles of 40 to 50 minutes.
