VIVOHOME HVAC Vacuum Pump 1/2 HP 5 CFM A2L-Compatible Sparkless 2-Stage with Oil

The VIVOHOME A2L 1/2 HP 5 CFM 2-stage vacuum pump is a sparkless, explosion-resistant HVAC pump built to evacuate refrigeration and air-conditioning systems to as low as 15 microns (0.2 Pa) while supporting modern A2L refrigerants.

This compact, portable pump combines a high-torque copper motor, a two-stage pumping action and multiple inlet fittings so technicians can service automotive A/C, residential and commercial refrigeration, and HVAC lines that use both legacy and newer low-GWP refrigerants. Designed for workplace safety and repeated field use, the unit includes vacuum oil, easy oil access, and thermal protection to reduce downtime and maintenance.

How does the two-stage design improve evacuation speed and depth?

The two-stage configuration gives progressive compression that achieves a deeper vacuum than single-stage units and reduces the time needed to reach low microns. This means faster pull-downs and more reliable removal of moisture and non-condensables from sealed systems.

• 5 CFM rated flow for quicker system drawdown
• Two-stage pumping for lower ultimate vacuum (around 15 microns / 0.2 Pa)
• Intake filter to keep particulates out of the pump cavity
• Exhaust fitting to separate oil mist from expelled gas

Is this pump compatible with A2L and other refrigerants?

Yes — the VIVOHOME A2L pump is built with a sparkless, explosion-resistant motor that supports A2L low-flammability refrigerants like R32, R1234yf and R454B, while also working with common refrigerants including R410A, R134a, R12, R22 and others. Multiple inlet fittings increase adaptability across service tasks.

• Explosion-proof, sparkless motor suitable for A2L refrigerants
• Includes 1/4" SAE, 3/8" SAE and 1/2" ACME inlet fittings
• Accepts a wide range of refrigerants for HVAC and auto A/C work
• Helps meet field requirements when switching refrigerant types

What convenience and maintenance features does it include?

The pump offers user-friendly service points like an easy-fill oil port, a visible oil window, and a bottom drain for fast oil changes. Portability is improved with a light chassis and ergonomic handle, and two bottles of vacuum oil are included to get you started.

• Oil sight window for quick level checks
• Simple oil filling port and bottom drain valve for cleaner servicing
• Ergonomic handle and lightweight die-cast aluminum housing
• Comes with 330 ml + 230 ml vacuum oil bottles

How safe and reliable is the pump during extended use?

Safety and longevity are addressed with thermal motor protection, a dedicated cooling fan, T-shaped heat fins, and mesh vents to keep the motor and pump cooler under load. The durable die-cast aluminum body and non-slip rubber base reduce vibration and extend working life.

• Thermally protected motor prevents overheating
• Built-in cooling fan and heat fins for effective dissipation
• Non-slip rubber base for stable operation on job sites
• Quiet operation reduces noise in the workspace

Who is this for: The VIVOHOME A2L 1/2 HP 5 CFM two-stage vacuum pump suits HVAC technicians, automotive A/C specialists, refrigeration installers, and maintenance professionals who need a portable, safe, and fast pump that supports modern low-GWP refrigerants and common legacy gases. If you require a sparkless, field-ready pump with multiple fittings, easy servicing and reliable deep vacuum capability, this model is built for those applications.
