VIVOHOME 1/4 HP 3.5 CFM Rotary Vane Vacuum Pump 110V — Single-Stage, Fast 5 Pa Evacuation

The VIVOHOME 110V 1/4 HP 3.5 CFM single-stage rotary vane vacuum pump quickly evacuates A/C systems while offering durable construction and user-friendly controls.

Engineered for HVAC technicians, home mechanics, and DIYers who service small to medium air conditioning and refrigeration systems, this VIVOHOME vacuum pump balances compact portability with measurable performance. Its 1/4 HP (180W) motor runs at 1440 r/min to deliver up to 3.5 CFM and reaches an ultimate vacuum around 5 Pa in roughly three minutes under typical conditions. Built-in protections and filtration extend service life and keep operation clean and quiet.

How fast will this pump evacuate my A/C system?

The pump is designed for quick evacuation of typical automotive and residential A/C loops. With a rated flow of 3.5 CFM and a strong motor, it achieves deep vacuum levels in minutes when paired with properly sized hoses and fittings. Actual time depends on system volume and leak tightness.

• 3.5 CFM flow rate for efficient evacuation
• Reaches about 5 Pa (ultimate vacuum) in ~3 minutes under ideal conditions
• Best performance with correctly sized hoses, valves, and minimal leaks

Which refrigerants and fittings does the VIVOHOME pump support?

This pump supports a broad range of common refrigerants and offers two intake connection options to fit varied service setups. It handles R134a, R12, R22, and R502 directly; R410A can be used with a 5/16-inch adapter (adapter not included). Both 1/4-inch SAE and 1/2-inch Acme intake fittings provide flexible hookup choices.

• Compatible with R134a, R12, R22, and R502
• R410A usable with 5/16" adapter (sold separately)
• Includes 1/4" SAE and 1/2" Acme intake fittings for varied equipment

What safety and durability features protect the pump?

VIVOHOME built multiple protections into the unit to reduce wear and prevent common failure modes. An advanced motor current protection system guards against overload and phase loss, while internal filtration traps contaminants and oil mist. The one-piece die-cast aluminum housing and four-pole pure copper motor deliver resilience in workshop environments.

• Motor current protection for overload and phase-loss safety
• 304 stainless steel coarse inlet filter and exhaust cotton layer filter
• Die-cast aluminum housing and pure copper motor increase durability

How easy is it to operate and maintain this vacuum pump?

The pump’s controls and service points are arranged for straightforward daily use. An ergonomic handle, simple ON/OFF switch, and a clear oil-view window make operation and monitoring intuitive. Oil changes are simplified by a bottom drain valve, and noise is kept near 65 dB thanks to an integrated cooling fan and a non-slip base for stable placement.

• Ergonomic grip and accessible ON/OFF switch for portability
• Clear oil sight window and bottom drain valve for quick maintenance
• Low-noise, fan-cooled operation with non-slip base for stability
