VIVOHOME HVAC Vacuum Pump 110V 1/3 HP 4.5 CFM — Single-Stage, Reaches ~5 Pa Fast

The VIVOHOME 110V 1/3 HP 4.5 CFM single-stage vacuum pump is a compact, rugged tool designed to evacuate refrigerant lines quickly and reliably for HVAC and automotive air conditioning work.

This vacuum pump pairs a 250W (1/3 HP) motor with a die-cast aluminum body to deliver 4.5 CFM airflow and reach an ultimate vacuum down to 5 Pa in minutes. Built for technicians and advanced DIYers, it supports multiple refrigerants through a standard 1/4" SAE inlet and can adapt to R410A with a 5/16" adapter (not included). The pump emphasizes safety and serviceability with protective electrical features, inlet filtration, an exhaust mist layer, and easy oil monitoring and draining.

How quickly will this pump evacuate refrigerant lines?

Thanks to its 1/3 HP motor running at 1728 r/min, the VIVOHOME pump moves air at 4.5 CFM and can reach deep vacuum levels fast. In typical service conditions it can pull down to about 5 Pa within minutes, reducing wait time on site.

• 4.5 CFM airflow for efficient evacuation
• Ultimate vacuum ~5 Pa under optimal conditions
• 250W motor speed 1728 r/min for consistent performance

Which refrigerants and systems does this pump work with?

The pump covers common refrigerants used in automotive and residential HVAC systems, with a standard 1/4" SAE inlet for broad compatibility. For R410A systems you can use a 5/16" adapter (sold separately) to connect properly and safely.

• Compatible with R134a, R12, R22, R502
• R410A supported via 5/16" adapter (not included)
• Standard 1/4" SAE inlet for common service hoses and gauges

What safety and durability features protect the pump during field use?

Built for repeat service calls, the unit uses a one-piece die-cast aluminum housing and a four-pole pure copper motor to resist impact and wear. Internal protections and filtration keep contaminants and electrical faults from causing damage, helping extend service life.

• Built-in motor current protection against overload or phase loss
• 304 stainless steel coarse inlet filter to block debris
• Exhaust cotton layer traps oil mist and particles

How easy is routine maintenance and operation?

VIVOHOME designed the pump for straightforward checks and servicing: a clear oil sight window, bottom drain valve, ergonomic handle and a simple ON/OFF switch make oil level monitoring and changes fast and clean. Non-slip feet and an integrated cooling fan contribute to steady, low-noise operation on the job.

• Clear oil sight window for quick oil checks
• Bottom drain valve for spill-free oil changes
• Ergonomic handle, non-slip base, and ~65 dB noise level

Who is this for: The VIVOHOME 110V 1/3 HP 4.5 CFM vacuum pump is aimed at HVAC technicians, mobile AC service professionals, and experienced DIYers who need a portable, dependable evacuation tool. It suits frequent field use where fast pull-down times, durable construction, and easy maintenance are priorities. If you service multiple refrigerant types or perform recurring evacuations, this unit balances performance and protection for professional-level jobsite demands.
