VEVOR 4.5 CFM AC Vacuum Pump & Gauge Set — Single-Stage, R134a to R407C

Meet the VEVOR 4.5 CFM AC Vacuum Pump and Gauge Set, a compact, rugged kit engineered for automotive A/C service, HVAC maintenance, and refrigeration tasks. The system pairs a single-stage vacuum pump with a durable four-stage copper motor to deliver up to about 3.5 CFM of flow and achieve an ultimate vacuum around 5 Pa. This combination supports efficient evacuation in busy shops and on-site jobs without sacrificing portability.

Universal refrigerant compatibility is at the core of this kit. It supports a wide range of common refrigerants, including R134a, R22, R12, R502a, R410A, R404A, and R407C. That versatility makes it suitable for automotive A/C work, HVAC upkeep, and mid-sized refrigeration tasks where multiple refrigerants may appear over time.

Precise monitoring for confident service

The upgraded PRO manifold gauge delivers real-time readings with about ±1.6% accuracy and enhanced pressure resistance. A large viewing glass keeps measurements easy to read, helping you verify system conditions as you work.

Secure connections, clear identification

The kit includes three color-coded hoses (red, blue, yellow) at 3.94 ft (1200 mm) for quick identification and secure connections. With a working pressure range of 800 PSI to 4000 PSI, these hoses are built to handle demanding jobs while staying flexible in various environments.
