VEVOR AC Vacuum Pump and Gauge Set, 3.5 CFM 99 L/min, Single Stage Rotary Vane HVAC Vacuum Pump, A/C Manifold Gauge Kit, for R134a R22 R410a R1234YF R32, with Carry Bag, for Auto HVAC Air Conditioning

Single Stage Rotary Vane Pump Rated at 3.5 CFM Output

This single stage rotary vane pump delivers 3.5 CFM / 99 L/min of free air displacement, the smallest output in this pump family, and is sized for lighter, less frequent A/C service work rather than continuous shop use. With a single-stage rotary vane design, the internal mechanism is simpler than that of a two-stage pump, making the unit lighter and easier to handle in the field or for occasional home use.

That lower CFM rating doesn’t mean reduced capability for smaller jobs; it just means longer evacuation times on larger systems compared to higher-output pumps. This level of output is in line with real-world usage for someone servicing a single vehicle or doing casual A/C repairs, rather than operating a full-time shop without paying for unused capacity. It’s a pump made for right-sizing at a smaller scale, less often.

Compact 1/4 HP Motor Suited for Light, Occasional A/C Work

This single stage rotary vane pump is driven by a 1/4 HP, 180W motor, the lightest in the lineup, and is designed for shorter evacuation cycles on smaller automotive A/C systems rather than extended, repeated commercial use. That smaller motor makes the overall unit lighter and more portable, which is important for anyone moving the kit between job sites or storing it in a toolbox rather than on a fixed shop bench.

A 4-pole high-torque design still provides enough steady pull to reach the proper vacuum depth with the smaller motor, but it lacks the extended-duty stamina of larger motors built for back-to-back commercial jobs. This motor size matches the pump's frequency of use for a DIYer or technician who does AC work only occasionally, not daily. It is designed for the size of jobs most home and light-duty users actually face.

Manifold Gauge Set Offers ±1.6% Pressure Reading Accuracy

The included manifold gauge set provides ±1.6% of reading accuracy, accurate enough to properly charge or diagnose an A/C system without guessing at pressure levels. It’s that accuracy that counts, regardless of pump size. Poor charging practices can damage components or leave a system undercharged, regardless of how powerful the vacuum pump itself is.

Dual-unit display means you don’t need a separate conversion chart to read pressure in different formats, and a clear oil window gives you another quick reference point on the job. The gauge housing is designed for high pressure and can withstand multiple connect-and-disconnect cycles across several smaller jobs. Even with a lighter-duty pump, this gauge set has the same measurement reliability as the larger kits in the family.

Three-Color Hose Rated for 800 to 4000 PSI Working Pressure

A 3.94 ft / 1.2 m three-color hose set rated in red, blue, and yellow is included, making it easy to identify high-side, low-side, and utility connections at a glance during service. That color coding helps prevent cross-connecting lines, especially handy for the less experienced do-it-yourselfers doing A/C work for the first time.

These hoses are rated for 800 to 4000 PSI working pressure, providing enough margin to safely handle refrigerant system pressures without a high risk of hose failure mid-job. The line is sealed through the vacuum and recharge stages by tight fittings at each connection point. With hoses rated this high, this unit does not skimp on pressure capacity compared to a lighter-duty kit.

Adapters Included for R134A, R410A, and R1234YF Refrigerant Systems

The kit comes with an R134a-to-R1234yf adapter, an R134a quick coupler, an R410A 1/4" SAE-to-5/16" SAE adapter, and R134A and R1234yf can taps to fit the connection types found on most common automotive refrigerant systems. Compatible refrigerants include R134a, R22, R410A, R1234YF, and R32, so the kit can be used on both older vehicles and newer models that meet current refrigerant standards.

This adapter range means you don’t have to source individual fittings, even for a small entry-level kit like this one. This coverage also means you won’t have to buy again later when you encounter a different refrigerant system if you only work on one vehicle or a few types of refrigerants. This consistency of completeness applies to the entire pump family, regardless of pump size.

Single Stage Rotary Vane Pump Kit Fits in a Portable Carry Bag

The smaller, lighter parts all fit in an included carrying bag to keep them organized in one place. This kit includes the pump, gauges, hoses, adapters, couplers, and a 0.21 qt / 200 ml oil bottle. That portability aligns with the general positioning of this pump as a compact, occasional-use kit rather than a heavier duty shop setup.

It’s also helpful for keeping smaller parts, such as adapters or can taps, from getting lost between uses, especially for kits that don’t get daily use. Pre-packing it and having it ready to go saves setup time when the next job comes up for someone who only needs this single stage rotary vane pump a few times a year. The bag makes this lighter kit a grab-and-go self-contained unit, just like its bigger brothers.
