Mastercool 90066-2V-110-BL Black Series 6 CFM 2-Stage Vacuum Pump 1/2 HP 110V For Sale

The Mastercool 90066-2V-110-BL Black Series 6 CFM Two-Stage Vacuum Pump is engineered for heavy-duty HVAC and automotive AC refrigerant evacuation. Driven by a 1/2 HP motor running at 1720 RPM, this industrial-grade pump achieves an ultimate vacuum down to 15 microns. Built for longevity in grueling shop or field conditions, it features an expanded internal oil path to minimize friction and heat, upgraded high-performance seals, and an integrated gas ballast valve that eliminates moisture contamination in the oil reservoir.

Equipped with three direct inlet ports (1/4\" SAE, 3/8\" SAE, and 1/2\" ACME) and a built-in manifold valve to isolate the pump during leak checks, it offers maximum setup flexibility. Active cooling fins combined with a high-volume fan protect the motor during extended operation, while an internal check valve prevents oil back-flow into the system.

Key Features

• 6 CFM 2-Stage Evacuation: Pulls down to 15 microns rapidly for thorough deep vacuum service on auto and stationary AC systems.

• 1/2 HP Motor: Operates on 110V/220V (50/60 Hz) with thermal overload protection and a simple rocker power switch.

• Triple Inlet Ports: Features 1/4\" SAE, 3/8\" SAE, and 1/2\" ACME connections to handle various system hoses without additional adapters.

• System Isolation Manifold Valve: Integrated valve lets you isolate the pump from the refrigeration circuit to test for system vacuum leaks.

• Gas Ballast & Check Valve: Gas ballast prevents moisture buildup in the oil, while the internal check valve prevents back-flow into the vacuum line.

• Superior Thermal Management: High-volume cooling fan and external cooling fins keep operating temperatures low under continuous load.

• Maintenance Friendly: Features a large oil sight glass with min/max indicators, an easily accessible oil drain valve, and a removable vapor discharge/oil fill port.
