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

The VIVOHOME A2L 1/3 HP 4.5 CFM HVAC vacuum pump is a sparkless, single-stage evacuator engineered to pull systems down to 150 microns (2 Pa) safely for modern refrigerants.

This compact pump combines ignition-proof design and a durable copper motor to support A2L-class refrigerants (R32, R1234yf, R454B) while remaining compatible with traditional refrigerants such as R410A and R134a. With a 4.5 CFM flow rate, filtration for dust and oil mist, and built-in thermal protection, it streamlines evacuation tasks across automotive, residential and light commercial HVAC, vacuum oven, lab, and packaging applications.

How does this pump handle flammable A2L refrigerants safely?

The unit uses a sparkless ON/OFF switch and ignition-proof components to reduce the risk of ignition when working with mildly flammable refrigerants. Design choices focus on containment and safe electrical control so technicians can evacuate A2L systems with greater peace of mind.

• Spark-resistant switch and internal ignition-proof parts
• Die-cast aluminum housing for robust containment
• Suitable for R32, R1234yf, R454B and standard refrigerants

What vacuum performance and filtration can I expect?

This pump delivers 4.5 cubic feet per minute and reaches an ultimate pressure of roughly 150 microns (2 Pa), making it suitable for thorough system evacuation. Intake and exhaust filters keep particulates and oil mist out of the work area and pump internals, extending service life.

• 4.5 CFM flow for efficient evacuation
• Ultimate total pressure: 150 microns; partial pressure: 2 Pa
• Intake dust filter and exhaust oil-mist trap included

How reliable is the motor and what maintenance features help long-term use?

A 1/3 HP copper-wound motor paired with thermal protection reduces overheating risk and mechanical wear. The pump includes practical maintenance elements—an oil-fill port, clear sight window, and quick-drain valve—so routine service is straightforward and fast.

• Copper motor with thermal cutoff and cooling fan
• Clear oil sight window for easy level checks
• Quick-drain valve and included 330 ml vacuum oil for immediate use

How quiet and portable is this model for workshop or field work?

Engineered for low acoustic footprint, the pump operates below 65 dB, helping maintain a calmer work environment. Lightweight construction, a non-slip rubber base, and compact dimensions make it convenient to carry between job sites or position in tight workspaces.

• Noise rating under 65 dB for reduced workplace disturbance
• Lightweight die-cast aluminum body with rubber anti-slip feet
• Carry-friendly size suitable for service vans and small shops

Who is this for: HVAC technicians, automotive AC professionals, laboratory staff, small-scale packaging operators, and hobbyists who need a dependable, spark-resistant evacuation tool. If you require safe A2L refrigerant compatibility, clear maintenance access, and strong vacuum performance in a portable package, the VIVOHOME A2L 1/3 HP 4.5 CFM pump is designed to meet those needs without excess complexity.
