VIVOHOME 1/2 HP 5 CFM Dual-Stage Rotary Vane Vacuum Pump — 110V, 0.3 Pa Ultimate Vacuum, Portable

The VIVOHOME 110V 1/2 HP dual-stage rotary vane vacuum pump creates a rapid, deep vacuum for HVAC service, reaching 0.3 Pa and removing moisture and air before refrigerant charging.

This compact, workshop-ready pump combines a 1/2 horsepower motor, dual-stage vacuuming, and robust safety features to help technicians and experienced DIYers evacuate automotive and residential air conditioning systems. Built with a die-cast aluminum housing and a two-pole pure copper motor, it balances portability with durable construction. The pump supports common refrigerants like R134a, R12, R22 and R502, and can accept R410a with a 5/16-inch adapter, offering flexible compatibility for a wide range of service tasks.

How quickly does this pump evacuate an AC system?

The VIVOHOME dual-stage design accelerates deep vacuuming so you can complete evacuations faster than single-stage pumps. In typical use it attains an ultimate vacuum of 0.3 Pa in about three minutes under recommended conditions, cutting downtime during maintenance or retrofits.

• 1/2 HP (375W) motor running at 2880 r/min for strong suction
• 5 CFM flow rate for efficient air and moisture removal
• Dual-stage configuration for faster, deeper evacuation
• Reaches 0.3 Pa in approximately 3 minutes in standard setups

What connections and refrigerants does it support?

Designed for broad compatibility, the pump includes common intake fittings and works with most legacy refrigerants used in HVAC service. If you need to service R410a systems, a 5/16-inch adapter (not included) enables its use without additional modification.

• Includes 1/4-inch SAE and 1/2-inch Acme intake fittings
• Compatible with R134a, R12, R22, and R502 refrigerants
• R410a workable with a 5/16-inch adapter (adapter sold separately)
• Versatile for automotive, residential, and light-commercial service

What safety and maintenance features are included?

Safety is addressed through motor current protection and multi-stage filtration that traps contaminants and oil mist, helping preserve pump internals and extending service life. User-focused elements like a clear oil viewing window and a bottom oil drain valve reduce mess and simplify routine maintenance.

• Motor current protection guards against overload and phase loss
• 304 stainless steel coarse inlet filter blocks large contaminants
• Exhaust cotton layer filter captures oil mist and impurities
• Clear oil sight window and bottom drain valve for easy oil checks and changes

How portable and user-friendly is the VIVOHOME pump?

The unit was engineered for field portability and straightforward operation, with an ergonomic handle, intuitive on/off switch, and low-noise performance for comfortable workshop use. A built-in cooling fan and non-slip base add stability during prolonged tasks.

• One-piece die-cast aluminum housing for strength and lighter weight
• Ergonomic grip handle and simple controls for ease of transport
• Operating noise around 65 dB and built-in cooling fan for quieter runs
• Non-slip base reduces vibration and improves stability on job sites

Who is this for: The VIVOHOME 110V 1/2 HP dual-stage vacuum pump is intended for HVAC technicians, experienced DIYers, and small shop owners who need a reliable, fast-acting evacuation tool for refrigerant service and system diagnosis. It’s suitable for automotive A/C work, residential heat pumps, and light commercial systems, especially when portability, durable construction, and practical maintenance features are priorities. Note that adapters for R410a and any specialized manifold or gauges should be selected separately to match your service requirements.
