High-Vacuum 3CFM Single Stage Automotive AC Vacuum Pump Portable Refrigerant Evacuation Kit With Manifold Gauge Set
The High-Vacuum 3CFM Single Stage Automotive AC Vacuum Pump is engineered as a compact yet powerful evacuation solution for mobile technicians, small repair shops, and DIY automotive enthusiasts who demand professional-grade vacuum performance in a portable and affordable package. Despite its single-stage rotary vane configuration, this pump achieves an ultimate vacuum of 5 Pascal through precision machining of the rotor housing, optimal vane material selection, and carefully controlled internal clearances that minimize gas back-streaming from the exhaust to the intake side. The 1/4 horsepower electric motor delivers 3.0 CFM of free air displacement at 1440 RPM, providing sufficient pumping capacity for evacuating most passenger vehicle AC systems within 20 to 30 minutes of operation. The pump is supplied as a comprehensive kit including a complete manifold gauge set, three color-coded service hoses, and a bottle of genuine vacuum pump oil, enabling technicians to begin AC service work immediately upon delivery without sourcing additional tools or accessories.
The pump housing is fabricated from high-grade die-cast aluminum with an attractive blue powder-coated finish that resists workshop chemicals, refrigerant oils, and incidental impacts. An ergonomic carrying handle integrated into the top of the housing facilitates easy transport between service bays or vehicle locations. The 250 milliliter oil reservoir features a clear sight glass for quick level checks, and the externally accessible oil drain plug simplifies routine oil changes without requiring disassembly of the pump module. Noise levels are kept below 58 decibels through precision rotor balancing and rubber-isolated motor mounts, making this pump suitable for use in noise-sensitive environments such as residential garages, apartment complex parking areas, and mobile service vans operating in urban settings. The dual-voltage motor accepts both 110V and 220V electrical supplies, with a simple voltage selector switch conveniently located on the motor terminal box for field configuration.
Key Features- Portable 7.2kg Design: Compact and lightweight construction with integrated carry handle enables single-person transport between service locations, ideal for mobile AC repair technicians and workshop environments with limited bench space.
- Complete Service Kit Included: Ships with a professional manifold gauge set featuring large-diameter easy-read dials, three color-coded refrigerant service hoses with quick-connect fittings, and a bottle of ISO VG 68 vacuum pump oil for immediate operation upon delivery.
- 5 Pa Ultimate Vacuum: Precision-machined rotary vane chamber and carefully selected vane materials deliver deep vacuum performance suitable for thorough moisture removal from automotive AC systems prior to refrigerant charging.
- Quiet 58 dB(A) Operation: Vibration-isolated motor mounts and dynamically balanced rotor assembly minimize operating noise, enabling comfortable use in residential areas, enclosed workshops, and mobile service vehicles without disturbing neighbors or colleagues.
- Dual Voltage Flexibility: Field-selectable 110V/220V motor configuration with clearly marked voltage selector switch accommodates global electrical grid standards, eliminating the need for external transformers when used in different countries or regions.
- Quick-Access Oil Maintenance: Externally mounted oil drain plug and large-diameter fill port enable fast oil changes without partial disassembly of the pump module, encouraging regular maintenance that extends pump service life and preserves vacuum performance.
- Blue Powder-Coated Finish: Attractive and durable surface treatment provides corrosion resistance against refrigerant oils, brake cleaners, and other common workshop chemicals while maintaining a professional appearance throughout years of service.

This high-vacuum portable AC vacuum pump serves a diverse range of automotive air conditioning service applications where portability and value are primary considerations. Mobile AC repair technicians will appreciate the lightweight design and comprehensive included accessory kit that eliminates the need to transport separate manifold gauges and hoses to each job site. Small independent repair shops operating with limited equipment budgets can equip multiple service bays with these pumps at a fraction of the cost of larger dual-stage units, improving workshop workflow and reducing technician wait times for shared equipment. Automotive DIY enthusiasts performing seasonal AC maintenance, compressor replacements, or system retrofits will find the plug-and-play kit format accessible and complete for home garage use. The pump is also well-suited for light commercial applications including refrigerated vending machine servicing, small walk-in cooler maintenance, and residential HVAC system evacuation. Automotive technical schools and vocational training programs benefit from the affordable per-unit cost when equipping entire classrooms with individual student workstations. Parts distributors and online retailers will find strong consumer demand for this product as an entry-point to professional-grade AC service equipment.
Packaging & Quality AssuranceEach unit is packaged in a durable blow-molded plastic carrying case with custom-fitted foam inserts that securely cradle the pump, manifold gauge set, hoses, and accessories during transit and daily transport between job sites. For bulk export shipments, individual cases are packed in reinforced double-wall corrugated master cartons with moisture-barrier liners and desiccant packets to protect against humidity during ocean freight. Every pump undergoes factory testing including minimum 20-minute run-in period, ultimate vacuum verification with calibrated electronic gauges, motor winding insulation resistance testing, and complete visual inspection. ISO 9001 certified manufacturing processes and CE and RoHS compliance documentation are provided for customs clearance in all major import markets. Custom OEM arrangements including private label branding on the pump housing and carrying case, custom color powder coating, and branded manifold gauge faces are available for qualifying order volumes. Standard lead time is 10 to 18 working days with flexible shipping options including air courier for urgent orders and consolidated sea freight for cost-sensitive bulk shipments.
