VIVOHOME A2L Vacuum Pump & 3-Way Manifold Gauge Set — 1/3 HP 4.5 CFM, Sparkless Safe Evacuation

The VIVOHOME A2L 1/3 HP vacuum pump and 3-way manifold gauge set is a compact, spark-resistant evacuation kit built for safe, fast removal of air and moisture from HVAC and automotive A/C systems using A2L refrigerants.

This integrated kit combines a 4.5 CFM single-stage vacuum pump with an A2L-compatible manifold, hoses and service fittings to let technicians and DIYers evacuate, diagnose and recharge systems that use low-flammability refrigerants such as R32, R1234yf and R454B. Design choices like a sparkless motor, ignition-proof switch and robust gauge scales focus on safer handling and reliable measurement during routine HVAC and mobile A/C work.

How does this pump handle A2L refrigerants safely?

The pump is designed with a sparkless motor and an ignition-proof on/off switch to reduce ignition risk when working with mildly flammable A2L refrigerants. Electrical protections and sealed die-cast housing further limit accidental sparking and help contain internal components.

• Sparkless motor and ignition-proof switch reduce ignition sources
• Die-cast aluminum housing minimizes leaks and protects internals
• Motor current protection prevents overheating during heavy use

How quickly and deeply can it evacuate an HVAC system?

Powered by a 1/3 HP motor at 1,728 RPM, the pump delivers 4.5 CFM of airflow for reasonably fast evacuation of small to medium systems. Its rated ultimate vacuum reaches approximately 15 microns (2 Pa), sufficient for removing most moisture and non-condensable gases prior to charging.

• 4.5 CFM flow rate for efficient evacuation
• Ultimate vacuum about 15 microns (2 Pa) for deep pulls
• Dual inlet ports (1/2" ACME and 1/4" SAE) for broad compatibility

What does the manifold gauge set include and how accurate is it?

The 3-way aluminum-bodied manifold comes with dual gauge cores and multiple refrigerant scales for common modern fluids. Each dial provides roughly ±1.6% accuracy and shows readings for R134a, R410A, R32, R1234yf and R454B, enabling clear diagnostics and service decisions.

• Three-color hoses with lock valves and quick couplers for R134a and R1234yf
• Self-sealing can taps and multiple adapters included for versatile service
• Manifold displays five refrigerant scales and ±1.6% gauge accuracy

How easy is it to transport and maintain this kit?

Weighing about 14.1 lb, the pump is lightweight and carries an ergonomic handle for field mobility. Visible oil sight glass and a bottom drain port streamline routine oil checks and changes, while included filters reduce exhaust contamination and noise.

• 14.1 lb portable pump with ergonomic handle and anti-slip base
• Visible oil window and bottom drain port for quick maintenance
• Stainless steel and oil-mist filters keep operation cleaner and quieter

Who is this for? technicians, HVAC service contractors, mobile automotive A/C pros and informed DIYers who work with modern low-GWP refrigerants will find this kit tailored to their needs. It balances portability and safety features for fieldwork, while the included manifold, hoses and adapters make it an all-in-one solution for evacuation, diagnostics and refrigerant service on small to medium systems.
