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

The VIVOHOME A2L 1/4 HP 3.5CFM vacuum pump and manifold gauge set is a sparkless, A2L-compatible HVAC service kit engineered to evacuate systems quickly and measure refrigerant pressures accurately.

This combined kit pairs a 1/4 HP (180W) single-stage vacuum pump that reaches an ultimate vacuum down to 2 Pa with a precision manifold gauge set tailored for modern refrigerants like R32, R1234yf and R454B. Built with safety features for mildly flammable refrigerants, durable fittings, and handy portability, the set is designed to streamline charging, evacuation, leak detection and routine maintenance on residential and light commercial air conditioning equipment.

How does this pump handle mildly flammable A2L refrigerants safely?

The vacuum pump uses a sparkless motor and an ignition-proof ON/OFF switch to reduce ignition risk when working with lower-flammability refrigerants. A 304 stainless coarse filter and oil-mist capture parts help contain contaminants and limit emissions, while motor protections prevent overheating during demanding draws.

• Sparkless motor and ignition-proof switch for A2L safety
• Oil mist cap and cotton exhaust filter to trap oil and reduce noise
• Motor current protection to avoid overload and phase loss
• 304 stainless coarse filter to block particulates entering pump chamber

How quickly and effectively will it evacuate an AC system?

Powered at 180W and running at 1,728 RPM, the pump provides 3.5 CFM flow and can reach an ultimate vacuum of about 2 Pa in roughly three minutes under ideal conditions. Those specs make it capable of fast system evacuation for most residential units and many light commercial applications.

• 1/4 HP (180W) motor delivering 3.5 CFM flow
• Ultimate vacuum approximately 2 Pa, fast pull-down time
• Visible oil window and bottom drain valve for easy maintenance
• Die-cast aluminum housing to reduce leakage points

What measurement and connection options are included for refrigerant service?

The gauge set blends the durability of an oil-filled core with the winter-ready performance of a dry dial, providing ±1.6% accuracy for reliable pressure readings. Multiple adapters and dual port sizes increase compatibility across R32, R1234yf, R410A, R134a and legacy refrigerants, while a large sight glass lets you monitor refrigerant flow during charging or recovery.

• ±1.6% accuracy manifold with oil-filled core and dry dial
• Large sight glass for refrigerant visibility
• Dual 1/2" ACME and 1/4" SAE ports plus four adapters included
• Scales for R32, R410A, R1234yf and R134a printed on gauge

How portable and quiet is the kit for jobsite use?

The pump weighs about 18.7 lb and has an ergonomic handle plus non-slip feet to simplify transport and placement. Noise-reduction measures — including an improved cooling system and exhaust filtration — keep operating sound under 65 dB for a quieter work environment.

• Compact 18.7 lb unit with ergonomic handle
• Non-slip feet and die-cast aluminum housing for stability
• Exhaust filters and improved cooling keep noise below 65 dB
• Visible oil window and bottom drain for quick upkeep

Who is this for: Technicians, HVAC contractors and advanced DIYers who service modern refrigerant systems will appreciate this VIVOHOME kit’s focus on safety, compatibility and measurement accuracy. It’s suitable for evacuation, refrigerant charging, recovery prep and other tasks on residential and light commercial AC units that use R32, R1234yf, R454B, R410A or common legacy refrigerants.
