VTG VOGTEN 4.5 CFM AC Vacuum Pump and Gauge Set for R134a

The VTGVOGTEN 4.5 CFM AC Vacuum Pump and Gauge Set is an all-in-one kit designed for automotive and residential air conditioning maintenance. Powered by a 1/3 HP 110V motor, this single-stage pump delivers a flow rate of 4.5 CFM (0.13 m³/m) to evacuate moisture and air from AC systems. An aluminum alloy casing helps dissipate heat during operation and resists chemical corrosion, offering dependable performance for DIYers and technicians working on mini-splits, HVAC systems, or auto repairs.

Diagnostics and servicing are straightforward with the included three-way manifold gauge. The dial provides direct readings for pressure in psi, temperature in degrees Fahrenheit, and refrigerant flow. It features a top hook so you can hang it up and keep your hands free while working. Connecting the setup is handled by three 4-foot color-coded rubber hoses (red for high-pressure, blue for low-pressure, and yellow for filling) that support a 600 psi working pressure and a 3000 psi burst pressure.

The package comes loaded with practical accessories to ensure broad usability across multiple refrigerants, including R134a, R12, R22, and R502. Inside the included storage bag, you get high- and low-pressure quick couplers, two R410a adapters (1/4-inch male to 5/16-inch female), puncture-style and self-sealing R134a can taps, a valve core wrench, a cleaning cloth, a user manual, and a bottle of vacuum pump oil.

A few operational requirements are worth noting before you get started. The pump runs strictly on standard 110V power, so you will need access to a compatible electrical outlet. Additionally, you must add the supplied pump oil prior to the first use to prevent overheating, and as a single-stage unit, it is built for standard evacuation needs rather than two-stage industrial deep vacuums.

Verdict: The VTGVOGTEN kit provides a comprehensive collection of diagnostic and evacuation tools in a single portable package. It is an excellent choice for anyone needing a reliable, ready-to-use setup for car air conditioning service, mini-split installation, or home HVAC maintenance.
