VIVOHOME HVAC Vacuum Pump A2L 1/4 HP 3.5 CFM — Sparkless Motor, 150 Micron Ultimate Vacuum

The VIVOHOME A2L 1/4 HP 3.5 CFM single-stage HVAC vacuum pump is a compact, sparkless unit designed to evacuate refrigerant systems down to deep vacuum levels while remaining compatible with new A2L refrigerants.

Built for HVAC technicians and refrigeration professionals, this pump combines a copper high-torque motor, explosion-resistant construction, and practical service features to speed evacuation, protect components, and simplify maintenance. It supports a wide range of refrigerants — including modern low-GWP A2L blends — and is intended for automotive AC, household refrigeration servicing, and light commercial HVAC work.

How quickly and deeply can this pump evacuate a system?

The pump delivers a 3.5 CFM flow rate and is capable of pulling down to about 150 microns (roughly 2 Pa) in an appropriately sized system. That level of vacuum is suitable for removing moisture and non-condensable gases from most refrigeration and air conditioning circuits before charging.

• 3.5 CFM continuous pumping capacity for efficient evacuation
• Ultimate vacuum around 150 microns (2 Pa) for thorough dehydration
• Intake filter and exhaust mist separator for clean operation

Is this pump safe to use with modern A2L refrigerants and older refrigerants?

Yes — the unit is engineered with a sparkless, explosion-resistant design that accommodates A2L refrigerants such as R32, R1234yf, and R454B, while remaining compatible with common legacy refrigerants like R410a and R134a. The construction and thermal protections reduce ignition risk and improve operational safety when handling flammable or mildly flammable blends.

• Explosion-proof, sparkless motor design for A2L use
• Compatible with a broad refrigerant list: R32, R1234yf, R454B, R410a, R134a, R12, R22, R502
• Thermal protection and fan cooling minimize overheating

What convenience features help during fieldwork and maintenance?

The pump includes practical details that make setup, monitoring, and oil changes straightforward. A visible oil sight glass, simple oil fill port, bottom drain valve, and a supplied bottle of vacuum oil speed routine service and reduce mess on the job.

• Oil sight window for quick level checks and timely refills
• Easy-fill port and bottom drain valve for cleaner oil changes
• Compact, lightweight body with an ergonomic handle for transport

How durable and quiet is the VIVOHOME pump for everyday use?

Constructed with a die-cast aluminum housing and non-slip rubber base, this pump resists wear and stays stable on work surfaces. Noise is reduced through design choices, and heat-dissipating fins plus a built-in fan protect the motor for longer duty cycles.

• Die-cast aluminum body for corrosion resistance and longevity
• Non-slip rubber feet to minimize vibration and movement
• Motor heat fins and mesh ventilation for effective cooling

Who is this for: HVAC and refrigeration technicians, mobile AC servicemen, and serious DIYers who need a portable, safe vacuum pump that supports the newest A2L refrigerants as well as legacy refrigerants. It’s best suited for small- to medium-sized systems where a 3.5 CFM single-stage pump provides the right balance of portability, performance, and safety features.
