VIVOHOME A2L 1/2HP Dual-Stage Vacuum Pump & 4-Way Manifold Gauge Set – Sparkless, 5 CFM, Compatible with R32/R1234yf

This all-in-one service kit pairs a 1/2 HP (375 W) dual-stage rotary vane vacuum pump that reaches deep vacuum quickly with a high-accuracy, color-coded 4-way manifold gauge set. Engineered for A2L refrigerants like R32 and R1234yf while remaining compatible with R410a, R134a, R12, R22 and R502, the package emphasizes safety, noise reduction, and field durability—making it practical for HVAC technicians, refrigeration professionals, and advanced DIYers.

How does this kit handle flammable A2L refrigerants safely?

The pump uses a sparkless, ignition-proof motor and an explosion-proof design to reduce ignition risk when working with lower-flammability refrigerants. Additional protective features like motor current protection and a stainless coarse filter help prevent contaminants and electrical faults from compromising safety.

• Sparkless motor and ignition-proof switch for reduced ignition risk
• Motor current protection guards against overload and phase loss
• 304 stainless coarse filter keeps particulates out of the pump chamber
• Metal exhaust cotton and layered metal exhaust capture oil mist

How quickly and effectively does the pump evacuate systems?

The 1/2 HP motor runs at 3456 rpm, delivering 5 CFM airflow and achieving a deep vacuum (0.2 Pa) in roughly three minutes under optimal conditions. Dual-stage design improves ultimate vacuum level and efficiency for accurate dehydration of refrigeration and air conditioning lines.

• 5 CFM airflow for fast evacuation of typical HVAC circuits
• 0.2 Pa achievable vacuum in about 3 minutes for efficient dehydration
• Dual-stage rotary vane mechanism for better ultimate vacuum
• Visible oil window and bottom drain valve simplify maintenance

What accuracy and durability can I expect from the manifold gauges and hoses?

The manifold offers ±1.6% reading accuracy with an oil-filled, wear-resistant core and a dry dial optimized for stable readings even in colder environments. Hoses are triple-layer reinforced rubber with leak-proof seals and color-coding to prevent connection mistakes and withstand shop wear.

• High-accuracy gauges with wear-resistant oil-filled cores
• Large sight glass and color-coded dials for quick flow monitoring
• Four triple-layer reinforced hoses: red, blue, yellow, black
• Shock-resistant gauge core, rubber-wrapped aluminum body, and zero-set calibration screw

How portable and serviceable is the unit for field work?

Weighing 19.5 lb with an ergonomic handle and non-slip feet, the pump is built for easy transport and stable operation on uneven surfaces. The die-cast aluminum housing minimizes leaks, while maintenance points like the oil sight glass and drain valve are integrated for quick checks and oil changes.

• Lightweight 19.5 lb design with ergonomic handle and non-slip feet
• Die-cast aluminum housing reduces leakage risk and improves durability
• Visible oil window and bottom drain valve for simple maintenance
• Enhanced cooling and noise-control features lower operating sound below 65 dB

Who is this for? The VIVOHOME A2L 1/2HP 5CFM dual-stage vacuum pump and 4-way manifold gauge set is intended for HVAC technicians, refrigeration service professionals, and serious DIYers who require a portable, accurate, and A2L-capable evacuation and charging solution. It’s well suited to shop and field service on split systems, heat pumps, refrigeration racks, and any application needing safe handling of modern refrigerants and reliable vacuum performance.
