VIVOHOME A2L Two-Stage Vacuum Pump and 4-Way Manifold Gauge Set — 3/4 HP, 7.2 CFM, Sparkless for R32/R454B

The VIVOHOME A2L 3/4 HP 7.2 CFM two-stage vacuum pump and 4-way manifold gauge set is a sparkless, service-ready HVAC kit built for fast, deep evacuations and accurate refrigerant diagnostics.

This all-in-one kit combines a two-stage vacuum pump engineered for A2L refrigerants with a professional 4-way manifold gauge and service hoses, enabling technicians to evacuate, test and charge residential and commercial air conditioning or refrigeration systems. It pairs a high-flow 7.2 CFM pump and 3/4 HP motor with durable fittings, clear gauges, and practical portability features so you can complete jobs faster while maintaining safer operation when working with low-flammability refrigerants such as R32 and R454B.

How does this pump handle A2L refrigerants safely?

The pump uses a sparkless motor design and an ignition-proof switch to reduce ignition risk during operation with A2L-class refrigerants. Its housing and controls are built to lower the chance of sparks or ignition sources near flammable gases, helping align with on-site safety practices.

• Sparkless motor and ignition-proof switch suitable for R32 and R454B handling
• Die-cast aluminum housing minimizes leakage and electrical hazards
• Oil mist exhaust filter reduces contaminated vapors in the work area

How fast and deep can it evacuate HVAC systems?

Powered by a 3/4 HP motor at 3456 r/min, the pump delivers 7.2 CFM of airflow, enabling quicker evacuation of medium to large systems. Its two-stage design can reach an ultimate vacuum down to about 1.5 microns (0.2 Pa), providing the deep vacuum level often required for moisture and non-condensable removal.

• 7.2 cubic feet per minute (CFM) for faster pump-down times
• Two-stage mechanism for deeper vacuum levels (≈1.5 microns)
• 80% duty cycle supports extended operation during larger jobs

What tools and connections come with the kit for service work?

The set includes a professional 4-way manifold gauge with dual cores and four refrigerant scales, plus color-coded hoses, lock valves and adapters to fit common service fittings. The manifold's ±1.6% accuracy and multiple refrigerant scales (R410A, R454B, R32, R22) simplify diagnostics and ensure readings match the refrigerant type in use.

• 4-way aluminum manifold with dual gauges and four refrigerant scales
• Four color-coded service hoses with lock valves for secure connections
• Multiple adapters and both 1/2" ACME and 1/4" SAE inlet ports for broad compatibility

How practical is the pump for transport and maintenance in the field?

The pump is built with portability and straightforward maintenance in mind; a molded handle and anti-slip base make it easy to carry and set down on uneven surfaces. Service-friendly features such as a visible oil window and a bottom drain port reduce downtime for oil checks and changes, and motor current protection helps prevent overheating during long procedures.

• Ergonomic handle and anti-slip base for easy carrying and stable setup
• Visible oil sight glass and bottom drain port for quick maintenance checks
• Motor current protection to reduce overheating risk during extended use

Who is this for? HVAC technicians, refrigeration service professionals, and experienced installers who require a high-capacity vacuum pump compatible with low-flammability A2L refrigerants and a reliable, accurate manifold gauge package. It suits jobs ranging from residential A/C installations to larger commercial refrigeration evacuations where deep vacuum performance, safety features, and quick diagnostics make the workflow more efficient.
