VIVOHOME 1/4 HP Rotary Vane Vacuum Pump 110V — 3.5 CFM, Single-Stage for HVAC Evacuation

VIVOHOME's 110V 1/4 HP rotary vane vacuum pump quickly evacuates A/C systems, delivering up to 3.5 CFM and reaching deep vacuum levels for reliable system evacuation.

This compact, single-stage vacuum pump pairs a 1/4 HP (180W) four-pole pure copper motor with a die-cast aluminum body to balance portability and durability. Designed for HVAC technicians and DIYers, it supports multiple refrigerants and provides protective features like motor current protection, filtration, and an oil sight glass for easy maintenance. Low operating noise and a built-in cooling fan make it suitable for workshop or field use.

How fast and deep can this pump evacuate an A/C system?

The VIVOHOME pump delivers a 3.5 CFM flow rate and can reach an ultimate vacuum around 5 Pa in roughly three minutes under ideal conditions. Its 1440 r/min motor and efficient rotary vane design prioritize rapid air removal so you can complete evacuation steps quickly.

• Flow rate: 3.5 cubic feet per minute (CFM)
• Ultimate vacuum: approximately 5 Pa
• Typical evacuation time to deep vacuum: about 3 minutes

Which refrigerants and fittings work with this pump?

This pump is made to support common refrigerants used in residential and light commercial systems. It includes dual intake fittings and can accommodate R410a with a separate adapter, offering broad compatibility across service tasks.

• Compatible refrigerants: R134a, R12, R22, R502 (R410a with 5/16-inch adapter)
• Intake fittings: 1/4-inch SAE and 1/2-inch Acme for flexible connections
• Adapter for R410a: sold separately (5/16-inch)

What safety and filtration features protect the pump and system?

The pump integrates motor current protection to guard against overload and phase loss during extended operation. Filtration layers reduce contamination and oil carryover, which helps preserve pump internals and keeps evacuated systems cleaner.

• Motor current protection prevents damage from overload or phase loss
• 304 stainless steel coarse filter blocks large contaminants
• Exhaust cotton layer captures oil mist and impurities

How is the pump designed for user convenience and maintenance?

VIVOHOME focused on ergonomic, maintenance-friendly design elements for fieldwork and shop use. From an oil viewing window to a bottom drain valve, the pump simplifies routine tasks so you can maintain performance with minimal downtime.

• Ergonomic grip handle and intuitive ON/OFF switch for easy transport and operation
• Clear oil sight glass and simple oil fill port for quick checks and refills
• Bottom oil drain valve for fast oil changes plus a non-slip base and cooling fan

Who is this for: The VIVOHOME 110V 1/4 HP 3.5 CFM single-stage rotary vane vacuum pump is aimed at HVAC technicians, automotive A/C specialists, and competent DIYers performing refrigerant evacuation and servicing. It suits those who need a portable, rugged pump with quick evacuation capability and built-in protections for routine system maintenance and refrigerant recharging tasks. If you require faster flow rates or two-stage deep vacuum performance for large or critical systems, consider higher-capacity or two-stage models; for everyday residential and light commercial service, this pump offers a solid balance of power, safety, and usability.
