VIVOHOME two-stage vacuum pump and 4-way manifold gauge set — 3/4 HP 7.2 CFM for A2L refrigerants, sparkless safety

The VIVOHOME A2L 3/4 HP 7.2 CFM two-stage vacuum pump and 4-way manifold gauge set is a sparkless, professional HVAC evacuation kit built to quickly reach deep vacuums and service A2L refrigerants like R32 and R454B.

This all-in-one kit combines a powerful two-stage vacuum pump with a precision 4-way manifold gauge and full hose/adaptor assortment so technicians can evacuate, diagnose, and charge residential or commercial HVAC and refrigeration systems reliably. Designed for modern lower-GWP refrigerants, the pump uses an ignition-proof switch and sparkless motor to reduce risk when handling A2L-class refrigerants. The set balances fast evacuation performance with portability, durable construction, and service-friendly features such as an oil sight glass and bottom drain.

How fast and deep can this pump evacuate a system?

The 3/4 HP motor spins at 3456 r/min delivering 7.2 CFM airflow, enabling quicker evacuation of medium to large systems compared with single-stage units. Its two-stage design helps achieve an ultimate vacuum around 1.5 microns (0.2 Pa), which is suitable for removing moisture and non-condensables before charging.

• 7.2 CFM airflow for faster pump-downs
• Two-stage mechanism for deeper vacuum levels (≈1.5 microns)
• Appropriate for medium to large residential/commercial systems

What safety and compatibility features support A2L refrigerants?

This VIVOHOME pump includes a sparkless motor and an ignition-proof switch specifically to reduce ignition risk when working with mildly flammable A2L refrigerants such as R32 and R454B. Multiple inlet ports and the set’s gauge scales ensure compatibility across common refrigerants used in modern HVAC service.

• Sparkless motor and ignition-proof switch for safer A2L handling
• Dual inlet ports: 1/2" ACME and 1/4" SAE adaptability
• Manifold gauges with scales for R410A, R454B, R32, and R22

What convenience and durability features help during long jobs?

The pump is built with die-cast aluminum housing, an ergonomic handle, and an anti-slip base for stable, portable operation. Maintenance is simplified with a visible oil window and a bottom drain port while oil mist exhaust filters reduce contamination and prolong working cleanliness.

• Die-cast aluminum body for reduced leaks and durability
• Visible oil sight glass and bottom drain for easy service
• Oil mist filter and motor current protection for reliable runtime

What comes in the complete service kit and how accurate are the gauges?

The set ships ready for service with the 7.2 CFM two-stage vacuum pump, a professional 4-way manifold gauge, four color-coded hoses with lock valves, and a range of adapters to fit common fittings. The manifold’s dual gauge cores offer ±1.6% accuracy and each dial includes four refrigerant scales for clear diagnostics during charging and recovery tasks.

• Included: vacuum pump, 4-way manifold, 4 color-coded lock hoses, adapters
• Manifold accuracy: ±1.6% for dependable readings
• Four refrigerant scales per dial for broad service coverage

Who is this for? HVAC technicians, refrigeration service professionals, and experienced contractors who need a portable, high-capacity evacuation solution for modern refrigerants will benefit most from this VIVOHOME kit. It’s suited to shop work and field service where deeper vacuum performance, A2L-safe operation, and accurate manifold readings speed up setup and troubleshooting without compromising durability or maintenance convenience. If you regularly evacuate medium to large systems or upgrade equipment to low-GWP refrigerants, this set provides the performance and features to support safe, efficient service jobs.
