VIVOHOME HVAC Vacuum Pump A2L 1/3 HP 4.5 CFM — Sparkless Motor, 150 Micron Deep Vacuum

The VIVOHOME A2L 1/3 HP 4.5 CFM HVAC vacuum pump is a sparkless, single-stage unit engineered to evacuate refrigeration and A2L refrigerant systems down to 150 microns (2 Pa) with quiet, oil-mist–controlled operation.

This compact pump combines sparkless ignition-proof controls and a 4.5 CFM displacement for reliable evacuation of modern refrigerants such as R32, R1234yf and R454B, while remaining compatible with traditional refrigerants like R410A and R134a. Designed for HVAC techs, automotive AC work, lab benches and small-shop use, it balances portability, safety features and service-friendly maintenance to get systems down to deep vacuum quickly and cleanly.

How does the VIVOHOME A2L pump handle flammable refrigerants safely?

This pump has a sparkless, ignition-proof on/off switch and motor design specifically intended for use with mildly flammable A2L refrigerants. Safety features reduce ignition risk during evacuation when used correctly and per refrigerant guidelines.

• Sparkless ON/OFF switch and ignition-proof motor housing.
• Compatible with R32, R1234yf, R454B and common non-flammable refrigerants.
• Die-cast aluminum case and sealed internal components for containment.
• Follow refrigerant handling rules and safe operating temperatures (41°F–104°F).

What evacuation performance and noise level can I expect?

The pump delivers 4.5 CFM displacement and achieves an ultimate total pressure of about 150 microns (2 Pa partial), enabling fast, deep evacuations for small to medium systems. It runs at a noise level below 65 dB, so it is suitable for shop or field environments where reduced noise is desired.

• 4.5 CFM for efficient evacuation time on automotive and HVAC systems.
• Ultimate vacuum: 150 microns total, 2 Pa partial pressure for deep pulls.
• Operating noise under 65 dB for quieter workspaces.
• Intake and exhaust filters minimize dust and oil mist during use.

How does maintenance and durability look for everyday use?

VIVOHOME engineered this unit with serviceability in mind: a clear oil sight window, easy-fill oil port, and a quick-drain valve simplify routine oil checks and changes. The copper motor, thermal protection, cooling fan and rugged die-cast aluminum housing combine to extend component life and resist heavy use.

• Clear oil window and supplied 0.35 qt (330 ml) vacuum oil to start immediately.
• Quick-drain valve for fast oil changes and clean maintenance.
• Thermally protected 1/3 HP copper motor with cooling fins and fan.
• Non-slip rubber base and double-layer baffle to reduce oil spray and vibration.

What applications is this vacuum pump best suited for?

This pump is versatile enough for HVAC service, automotive air conditioning, vacuum ovens, packaging, small labs and woodworking projects that require controlled vacuum. Its sparkless design makes it particularly useful when working with low-flammability A2L refrigerants or in environments where ignition prevention is important.

• Automotive and residential/commercial HVAC evacuation and maintenance.
• Vacuum oven cycling, packaging and lab sample prep.
• Small-scale woodworking and resin degassing.
• Field service work where portability and safety are priorities.

Who is this for: Technicians, shop owners and serious DIYers who need a portable, safety-focused vacuum pump that can handle modern A2L refrigerants and conventional refrigerants alike. If you require a balance of deep vacuum capability, low noise, serviceable components and sparkless operation for flammable-rated refrigerants, the VIVOHOME A2L 1/3 HP 4.5 CFM pump is engineered to meet those needs while remaining easy to maintain and transport.
