VIVOHOME HVAC Vacuum Pump A2L 1/4 HP 3.5 CFM Single‑Stage — Sparkless, Explosion‑Resistant

The VIVOHOME A2L 1/4 HP 3.5 CFM single-stage HVAC vacuum pump is a sparkless, A2L-compatible unit engineered to evacuate refrigeration and air-conditioning systems down to deep vacuum levels reliably.

This compact pump combines a copper high-torque motor, an explosion-resistant design, and user-friendly service points to serve technicians working with both modern low‑GWP refrigerants and legacy refrigerants. It is built to minimize mechanical wear while offering portability, clear service access, and safety features that protect motor life during extended jobs.

How does this pump handle A2L and other modern refrigerants?

Designed with an explosion-resistant architecture and a sparkless motor, this pump is suitable for mildly flammable A2L refrigerants such as R32, R1234yf, and R454B, while also remaining compatible with common refrigerants like R410A, R134a, R12, R22, and R502. The design reduces ignition risk and supports safe evacuation practices when paired with correct field procedures and fittings.

• Sparkless motor and explosion-proof construction for A2L use.
• Works with both low‑GWP and traditional refrigerants.
• Recommended to follow refrigerant-specific safety and service guidelines.

What vacuum performance and capacities can I expect?

This single-stage pump delivers a 3.5 CFM flow rate and is capable of pulling systems down to about 150 microns (approximately 2 Pa), which is sufficient for most HVAC and refrigeration evacuation tasks. An intake filter and exhaust oil-mist separation help keep the pumping cavity and worksite cleaner and more effective.

• 3.5 CFM flow suitable for automotive and residential HVAC systems.
• Achieves deep vacuum levels near 150 microns for thorough evacuation.
• Built-in intake filtration and exhaust mist separation improve longevity.

What convenience and maintenance features does it offer?

Serviceability was emphasized with a clear oil sight window, simple oil fill port, and a bottom drain valve for fast, complete oil changes. The unit ships with a 0.35 qt (330 ml) bottle of vacuum oil and includes a comfortable handle and a lightweight chassis for easy transport between jobs.

• Oil window for quick visual checks and a clean oil-fill port.
• Bottom drain valve speeds oil changes and reduces mess.
• Includes 0.35 qt vacuum oil and an ergonomic carry handle for portability.

How does the pump protect itself during extended use?

A thermally protected motor, an integrated cooling fan, T-shaped motor heat fins, and a mesh design help dissipate heat efficiently to prevent overheating. The die-cast aluminum housing adds rigidity and improves heat conduction, while the non-slip rubber base reduces vibration and holds the unit steady during operation.

• Thermal protection prevents motor damage from prolonged operation.
• Fan, heat fins, and mesh enhance cooling and extend motor life.
• Sturdy die-cast housing and rubber feet for durable, low-vibration performance.

Who is this for? Technicians and HVAC/R professionals who service cars, residential systems, or light commercial refrigeration will appreciate this VIVOHOME pump for its A2L readiness, compact portability, and practical maintenance features. It’s also a good choice for contractors who need a reliable, quiet, and durable single-stage vacuum pump for regular evacuation tasks while working with both modern low-flammability refrigerants and legacy refrigerants.
