VIVOHOME A2L Vacuum Pump & Manifold Gauge Set — 1/4 HP 3.5 CFM, Sparkless Safe for A2L Refrigerants

The VIVOHOME A2L 1/4 HP vacuum pump and manifold gauge set is a sparkless, portable HVAC service kit designed for safe evacuation and accurate pressure work on A2L and traditional refrigerants.

This combined vacuum pump and manifold gauge kit pairs a 1/4 HP (180W) sparkless motor vacuum pump delivering 3.5 CFM with a precision manifold gauge assembly. Built for compatibility across modern and legacy refrigerants—including R32, R1234yf, R454B, R410A and R134a—the set focuses on safe handling of mildly flammable A2L refrigerants, convenient on-site maintenance, and reliable measurement for charging and diagnostics.

How is the pump made safe for mildly flammable (A2L) refrigerants?

The pump includes an ignition-proof ON/OFF switch and a sparkless motor design to lower ignition risk when working with A2L refrigerants. Motor current protection helps prevent overload and phase loss, while filtration and exhaust controls reduce contaminants and mist.

• Sparkless motor and ignition-proof switch for safer operation
• Motor current protection to avoid overheating and damage
• 304 stainless steel coarse filter to block debris
• Oil mist cap and cotton exhaust filter to capture oil and reduce noise

What performance and compatibility can I expect during evacuation?

The pump runs at 1728 rpm and reaches an ultimate vacuum of about 2 Pa in roughly three minutes under ideal conditions, with a flow rate of 3.5 CFM that suits HVAC servicing, oil distillation, vacuum packaging, and resin deaeration. Multiple port sizes and adapters broaden connection options to many systems.

• 1/4 HP (180W) motor, 1728 r/min, 3.5 CFM flow rate
• Ultimate vacuum approx. 2 Pa (typical under proper conditions)
• Dual ports: 1/2” ACME and 1/4” SAE plus four adapters included
• Compatible with R32, R1234yf, R454B, R410A, R134a, R12, R22, R502

How accurate and durable is the manifold gauge for charging and diagnosis?

The manifold gauge delivers ±1.6% accuracy and combines a wear-resistant oil-filled core with a dry dial for reliable use in varied temperatures. Color-coded gauges, a large sight glass, and refrigerant-specific scales make readings straightforward while shock-resistant construction protects internal mechanisms.

• ±1.6% accuracy with oil-filled core and dry dial benefits
• Large sight glass for clear refrigerant flow observation
• Calibration screw and multi-refrigerant scales included
• Rubber-wrapped, shock-resistant housing with aluminum body

What makes this kit easy to carry and maintain on the job?

The pump weighs about 18.7 lb, includes an ergonomic handle, non-slip feet, and a die-cast aluminum housing to reduce leaks. Visible oil window and bottom drain valve simplify routine maintenance, while quieter operation under 65 dB supports longer use in occupied spaces.

• Lightweight 18.7 lb design with ergonomic handle and non-slip feet
• Visible oil window and bottom drain valve for easy servicing
• Enhanced cooling and noise reduction to below 65 dB
• Three reinforced, color-coded hoses with leak-proof seals

Who is this for? Technicians, HVAC contractors, and serious DIYers who work on modern A2L refrigerant systems or need a versatile servicing kit will find this VIVOHOME set useful. It fits professionals who require a compact, safer-for-A2L evacuation solution with accurate gauges, multiple adapters, and rugged construction for field service and shop work.
