VIVOHOME HVAC Vacuum Pump 3.5 CFM 1/4 HP — A2L Sparkless Motor, 150 Micron Rated (Compact, Explosion‑Resistant)

VIVOHOME A2L 1/4 HP 3.5 CFM single-stage HVAC vacuum pump is a sparkless, explosion-proof pump built to evacuate refrigerant systems down to 150 microns while supporting modern A2L refrigerants and common legacy gases.

This compact, single-stage pump combines a spark-resistant motor design with a 3.5 CFM displacement to deliver reliable evacuation for air conditioning, refrigeration, and automotive HVAC tasks. It includes user-friendly features—oil sight glass, simple fill port, bottom drain valve and an ergonomic handle—so technicians can set up, monitor and maintain the pump quickly on job sites or in workshops. Constructed from die-cast aluminum and fitted with thermal protection, the unit targets long-term durability and safe operation when paired with refrigerants like R32 and R1234yf as well as R410a and R134a.

How does this pump handle modern low‑GWP A2L refrigerants?

The VIVOHOME pump is designed with an explosion-resistant, sparkless motor to be compatible with mildly flammable A2L refrigerants such as R32 and R1234yf. Its materials and sealing reduce ignition risk while maintaining the vacuum performance required for contemporary HVAC service.

• Explosion-proof sparkless motor for A2L safety
• Compatible with R32, R1234yf, R454B plus R410a/R134a
• 3.5 CFM flow to reach down to 150 microns (≈2 Pa)
• Intake filter and exhaust oil separator protect internals

What vacuum level and flow can I expect for evacuating systems?

This single-stage pump delivers 3.5 cubic feet per minute (CFM) and is capable of drawing systems down to around 150 microns (approximately 2 Pa) under correct conditions. That makes it suitable for removing non-condensables and moisture from many sealed refrigeration and A/C circuits before charging.

• Rated 3.5 CFM pumping speed for efficient evacuation
• Achieves vacuum depths near 150 microns with proper setup
• Oil mist separator and intake filter for cleaner operation
• Includes 0.35 qt (330 ml) vacuum oil for immediate use

How easy is it to operate and maintain on the job?

The pump is built for straightforward field use: a visible oil window, easy oil fill port, and a bottom drain valve streamline routine maintenance. Lightweight housing and a comfortable handle make transport simple, while thermal motor protection and a cooling fan reduce the risk of overheating during extended runs.

• Oil sight glass and spill-resistant fill port for fast checks and refills
• Bottom drain valve enables quicker, more complete oil changes
• Ergonomic handle and compact form for portability
• Thermal protection and fan-cooled motor prolong service life

Will this pump withstand frequent shop or field use?

VIVOHOME constructed the pump with die-cast aluminum for a balance of strength and weight, plus a non-slip rubber base to stabilize operation. Noise is kept to a practical minimum, and anti-wear design choices aim to reduce maintenance intervals and extend working life.

• Durable die-cast aluminum housing resists wear and impact
• Non-slip rubber feet reduce vibration and movement
• Quiet operation suitable for indoor workshop environments
• T-shape motor fins and mesh design enhance cooling efficiency

Who is this for? Technicians, HVAC installers and mobile automotive A/C professionals who service systems using modern A2L refrigerants—yet still work with legacy refrigerants—will find this VIVOHOME pump useful. It’s designed for those who need a portable, sparkless evacuation solution with clear maintenance features and the capacity to reach deep vacuums for routine evacuation and dehydration of refrigeration circuits.
