VIVOHOME VG Series 1/2HP 5CFM 2 Stage AC Vacuum Pump and Manifold

The VIVOHOME VG Series 1/2HP 5CFM Vacuum Pump and Manifold Kit provides a complete evacuation and diagnostic setup for technicians and DIYers working on cooling lines. It addresses common servicing needs across residential, commercial, and automotive air conditioning systems, providing the necessary tools to pull deep vacuums and clear lines of air and moisture.

At the center of the kit is a dual-stage pump driven by a 3456 RPM high-torque copper motor. Delivering 5 CFM of airflow, it achieves a deep vacuum down to 15 microns to help minimize ice buildup in AC lines. The pump operates at or below 65 dB, utilizing dual exhaust filters to trap oil mist and internal anti-backflow valves to stop oil from migrating into the serviced system. The hardware relies on a reinforced aluminum body, cooling fins, an internal fan, and a solid iron base to manage heat and resist heavy shop wear.

For diagnostics and charging, the kit includes a manifold gauge set with a shock-resistant core, rubber casing, and an integrated hanging hook for hands-free work. A built-in calibration screw lets you quickly adjust the gauge readout when needed. Broad connection flexibility is supported via universal 1/4-inch SAE and 1/2-inch ACME inlets, handling refrigerants like R134a, R410A, R22, R12, and R502 alongside the supplied color-coded hoses and fittings.

When it comes to limitations, this equipment is strictly not compatible with A2L or A2 refrigerants. Users must also remember that the included quick couplers ship in the open position and must be manually closed before attaching to a vehicle. Additionally, at 19.3 pounds, the pump has some heft when transported between job sites.

Verdict: This comprehensive kit is an excellent choice for automotive mechanics, HVAC technicians, and serious DIYers looking for a reliable, quiet evacuation tool with all essential accessories included. It delivers everything needed out of the box for standard R134a, R410A, and R22 systems.

• Motor: 1/2 HP high-torque copper motor (3456 RPM)
• Flow Rate: 5 CFM
• Ultimate Vacuum: 15 microns
• Noise Level: ≤65 dB
• Weight: 19.3 lbs
• Inlet Ports: 1/4-inch SAE and 1/2-inch ACME
• Refrigerant Compatibility: R134a, R410A, R22, R12, R502 (Not for A2L/A2)
• Materials: Reinforced aluminum body, iron base, rubber-encased gauge

A great fit if you:

• Service automotive air conditioners using R134a or home systems using R410A and R22.
• Need a ready-to-run package with gauges, hoses, adapters, and pump oil supplied in one purchase.
• Want a quiet pump rated at 65 dB or less for enclosed garage or indoor work.
• Require a dual-stage pump capable of pulling down to 15 microns.

Consider something else if you:

• Work with newer mildly flammable A2L or A2 refrigerants.
• Need an ultra-lightweight pump for frequent rooftop carrying without extra bulk.

Can this vacuum pump be used with A2L refrigerants?
No, the unit is not compatible with A2L or A2 refrigerants.

What refrigerants does this manifold and pump kit work with?
The system fits R134a, R410A, R22, R12, and R502 refrigerants using the included adapters and universal inlets.

What accessories come in the box?
The kit contains the 5 CFM dual-stage pump, two bottles of vacuum oil, a manifold gauge set, three color-coded hoses, two R134a quick couplers, an R134a self-sealing can tap, and three port adapters.

How do I prepare the quick couplers for initial use?
The quick couplers ship in the open position, so you must turn the knob to the closed position before connecting them to service ports.
