VIVOHOME A2L 1/2 HP 5 CFM 2 Stage HVAC Vacuum Pump with

The VIVOHOME A2L 2-Stage Vacuum Pump is built for HVAC technicians and mechanics servicing modern cooling setups. Featuring a sparkless, explosion-proof design, it handles newer A2L refrigerants like R32, R1234yf, and R454B, as well as common blends like R410a, R134a, and R22. Its dual-stage mechanism paired with a 1/2 HP copper motor draws systems down to 0.2 Pa (15 microns) at a 5 CFM flow rate, making it suitable for automotive air conditioning, refrigeration, and general HVAC work.

Daily operation is straightforward thanks to practical maintenance features. A clear sight window allows quick checks on fluid levels, while the top oil filling port and bottom drain valve streamline fluid changes without mess. To protect system cleanliness, an intake filter blocks dust from entering the cavity, and an exhaust fitting separates oil mist from escaping gas. The pump also includes 1/4-inch SAE, 1/2-inch ACME, and 3/8-inch SAE inlet fittings to fit standard service hoses.

Durability and safety are supported by a die-cast aluminum housing and multiple cooling elements. A built-in fan, T-shaped cooling fins, and mesh venting work together with thermal motor protection to prevent overheating during long runs. For stability on the job, the base features non-slip rubber feet that keep the unit steady and reduce operating noise.

As with any mechanical vacuum pump, routine upkeep is required, including checking fluid levels and completing oil drains. While the listing highlights a portable build with an ergonomic handle, it does not state exact machine dimensions, total weight, or power voltage requirements, so buyers needing precise cabinet measurements will need to plan accordingly.

Verdict: This pump is an excellent option for HVAC specialists and automotive mechanics who need a reliable, sparkless dual-stage pump compatible with modern A2L refrigerants. It offers deep vacuum capability, multi-size fittings, and included oil right out of the box.

• Motor Power: 1/2 HP copper motor
• Flow Rate: 5 CFM
• Ultimate Vacuum: 0.2 Pa (15 Micron)
• Pump Design: 2-Stage
• Housing Material: Die-cast aluminum
• Inlet Fittings: 1/4-inch SAE, 1/2-inch ACME, 3/8-inch SAE
• Included Oil: 2 bottles (330 ml and 230 ml)
• Refrigerant Compatibility: R32, R1234yf, R454B, R410a, R134a, R12, R22, R502, R404A, R407C

A great fit if you:

• Service air conditioning systems that use mildly flammable A2L refrigerants like R32 or R1234yf.
• Need a deep vacuum down to 15 microns for automotive or residential HVAC evacuation.
• Want multiple inlet ports (1/4-inch SAE, 1/2-inch ACME, 3/8-inch SAE) to match different service hoses.

Consider something else if you:

• Require an oil-free pump that completely eliminates fluid monitoring and draining.
• Need confirmed voltage or exact physical dimensions before purchasing.

Which refrigerants is this pump compatible with?
It works with A2L refrigerants including R32, R1234yf, and R454B, as well as standard types like R410a, R134a, R12, R22, R502, R404A, and R407C.
