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 diagnostic and evacuation kit designed for servicing mini-split units, HVAC setups, and automotive air conditioning systems. By bundling a 1/3 HP vacuum pump with manifold gauges, hoses, and service adapters, it gives DIYers and technicians the essential equipment needed to pull vacuums and recharge systems without buying pieces individually.

At the center of the kit is a single-stage pump delivering a 4.5 CFM flow rate (0.13 cubic meters per minute). Built with a copper motor construction and housed in an aluminum alloy casing, the pump is engineered to manage operational heat dissipation while offering chemical corrosion resistance. The included three-way manifold gauge provides direct readings of temperature in Fahrenheit, pressure in psi, and refrigerant flow, and features a built-in top hook to keep your hands free during maintenance.

Connecting the setup are three 5-foot color-coded rubber hoses (red for high-pressure, blue for low-pressure, and yellow for filling) that support a working pressure of 600 psi and a burst pressure of 3000 psi. The kit covers multiple refrigerants, including R134a, R22, R410a, and R404a, thanks to included 1/4-inch to 5/16-inch R410a adapters, high- and low-pressure quick couplers, and both puncture-style and self-sealing R134a can taps. Everything packs away into a thickened trifold storage case with a bottle of vacuum oil, a leak detector, a screwdriver, and a valve core wrench.

As a single-stage pump, it is designed for standard service tasks rather than multi-stage deep vacuum needs. Users will also need to perform routine oil maintenance using the included vacuum oil. Additionally, the listing does not state the pump weight or the exact electrical cord length, which is worth considering when planning your workspace setup.

Verdict: The VTGVOGTEN vacuum pump set offers a thoroughly equipped, versatile package for automotive air conditioning, HVAC, and mini-split system maintenance. It is a solid choice for anyone looking for a complete kit with wide refrigerant compatibility and integrated tool storage.

• Motor Power: 1/3 HP
• Flow Rate: 4.5 CFM (0.13 m³/m)
• Pump Stage: Single stage
• Motor Material: Copper construction
• Casing Material: Aluminum alloy
• Hose Length: 5 feet
• Hose Working Pressure: 600 psi
• Hose Burst Pressure: 3000 psi
• Supported Refrigerants: R134a, R22, R410a, R404a
• R410a Adapters: 1/4 inch to 5/16 inch

A great fit if you:

• Need a complete kit with pump, gauges, hoses, and can taps for automotive or home AC repair
• Work across multiple refrigerants such as R134a, R22, R410a, and R404a
• Want an all-in-one package that stores neatly inside a single protective carrying case
• Service mini-split systems requiring 1/4-inch to 5/16-inch R410a adapters

Consider something else if you:

• Require a two-stage vacuum pump for specialized deep evacuation jobs
• Already own manifold gauges and adapters and only need a bare replacement pump
