Mastercool 90612-2V-110-BL Black Series 12 CFM Two Stage Vacuum Pump Dual Voltage 110/220V

The Mastercool 90612-2V-110-BL Black Series is a professional-grade 12 CFM two-stage vacuum pump designed for HVAC/R service and automotive air conditioning work. This dual voltage pump operates on both 110V and 220V power, featuring a thermally protected motor, high-volume cooling fan, and convenient oil drain valve for simplified maintenance.

Advanced Engineering Features:

• Refined cartridge machining process creates improved surface finish for extended pump longevity
• Expanded internal oil path reduces friction and heat buildup during operation
• Upgraded seals ensure maximum vacuum performance and reliability
• Easily removable vapor discharge/oil fill port for convenient servicing
• Gas ballast valve helps prevent oil contamination caused by high moisture conditions
• Manifold valve isolates pump from system during leak testing procedures
• Three inlet ports provide flexible connection options

This two-stage vacuum pump delivers deep vacuum capability essential for proper evacuation of refrigeration systems, removing moisture and non-condensables before charging. The thermally protected motor and high-volume fan ensure reliable operation even during extended use, while the oil drain valve simplifies routine maintenance. Ideal for professional technicians working with residential and commercial HVAC systems, automotive AC, and refrigeration equipment.
