VIVOHOME 1/2 HP 5CFM 2 Stage AC Vacuum Pump and 4 Way

The VIVOHOME 1/2 HP 5 CFM 2-Stage Vacuum Pump Kit is a comprehensive service package designed for vehicle HVAC repairs, system evacuation, and pressure testing. It pairs a dual-stage pump with a 4-way manifold gauge to handle deep evacuations down to 22.5 microns and an ultimate partial pressure of 0.3 Pa. This setup fits DIY mechanics and technicians who need a complete setup for refrigeration servicing, automotive air conditioning repair, and vacuum packaging tasks.

The dual-stage pump uses a 1/2 HP motor supported by an internal cooling fan, T-shaped heat fins, and mesh vents to disperse heat during extended use. To keep operation clean, an inlet coarse filter blocks dust while the exhaust port separates oil mist from outgoing air. An oil sight glass gives you an immediate view of the oil level and condition, and a dedicated drain port allows for fast oil changes between jobs.

Diagnostics and charging are managed through the 4-way manifold gauge, which includes a hanging hook for hands-free positioning. The kit features four 5-foot rubber hoses (red, blue, yellow, and black) rated for 800 psi working pressure and 4000 psi burst pressure. Compatibility is broad right out of the box, supporting R12, R134a, R22, and R410a systems thanks to the included 1/4-inch male to 5/16-inch female R410a adapters and a 1/4-inch SAE male to 1/2-inch ACME female adapter.

As a dedicated evacuation and pressure-testing kit, it comes with practical extras like a leak detector, puncture and self-sealing R134a can taps, quick couplers, and two bottles of vacuum oil (330 ml and 230 ml). Keep in mind that no refrigerant is included, so you must supply your own for charging tasks. Managing the numerous adapters, valve cores, and sealing gaskets also requires careful organization in the provided tote and carrying case.

Verdict: This VIVOHOME kit is a practical, all-in-one solution for anyone needing a reliable dual-stage pump and 4-way gauge set for HVAC maintenance. It provides all the core hardware, hoses, and adapters needed to evacuate and test multiple refrigerant systems efficiently.

• Motor Power: 1/2 HP
• Flow Rate: 5 CFM
• Pumping Stages: 2 stage
• Ultimate Vacuum: 22.5 microns (0.3 Pa partial pressure)
• Hose Length: 5 feet
• Hose Working Pressure: 800 psi
• Hose Burst Pressure: 4000 psi
• Refrigerant Compatibility: R12, R134a, R22, R410a
• Included Oil Volume: 330 ml + 230 ml bottles

A great fit if you:

• Need a dual-stage vacuum pump that reaches deep vacuum levels down to 22.5 microns.
• Work on automotive or residential systems using R12, R134a, R22, or R410a refrigerants.
• Want a complete package with hoses, can taps, leak detector, and vacuum oil included.
• Prefer a 4-way manifold gauge setup with dedicated vacuum and charging lines.

Consider something else if you:

• Need an all-inclusive charging bundle that comes with refrigerant canisters.
• Only require a simple single-stage pump for basic, infrequent household tasks.

Is refrigerant included with this kit?
No, refrigerant is not included or sold with this product. The kit is designed strictly for vacuuming, evacuation, and pressure testing.
