5 CFM Two-Stage Vacuum Pump - Mastercool

The Mastercool 90065 5 CFM Two-Stage Vacuum Pump is engineered for efficient and thorough evacuation of small to medium-sized refrigeration and air conditioning systems, typically ranging from 2.5 lb to 10 lb charge capacity. This robust, professional-grade pump is designed for reliable performance in both automotive and industrial applications, ensuring systems are properly prepared for charging.

Key Features

• Two-Stage Rotary Vane Design: This pump's two-stage design provides a deep ultimate vacuum of 25 microns, essential for complete system dehydration and evacuation.
• Integrated Manifold Valve: A built-in manifold valve allows technicians to isolate the pump from the system to verify a vacuum hold or perform maintenance without compromising the system's vacuum.
• Versatile Inlet Port Configuration: Equipped with 1/4" FL, 3/8" FL, and 1/2" ACME ports, this pump accommodates a wide range of hoses and is specifically suited for automotive R134a systems.
• High Efficiency Motor: A durable 1/3 HP motor drives the pump at 1725 RPM, delivering a consistent 5 CFM free air displacement for fast and effective evacuation.
• Durable Construction: Built with a lightweight yet tough die-cast aluminum housing, the Mastercool 90065 is designed to withstand the demands of professional daily use in workshops and mobile service environments.
• Gas Ballast Valve: An integrated gas ballast valve helps to reduce oil contamination, particularly in systems with high moisture, thereby extending the life of the pump oil.
