Mastercool 90612-2V-220SVBL Black Series 12 CFM 2-Stage Vacuum Pump with Solenoid Valve 220V

The Mastercool 90612-2V-220SVBL is a professional-grade 2-stage vacuum pump from the Black Series range, designed for HVAC engineers who need high-capacity evacuation with built-in protection against oil contamination. At 12 CFM (340 lit/min at 60Hz, 283 lit/min at 50Hz), it handles large commercial systems and multi-split installations with ease. The integrated solenoid valve is the key differentiator — it automatically isolates the pump from the system on power failure, preventing oil back-flow into the AC circuit.

Key Features

• 2-stage design — 15 micron ultimate vacuum for thorough system evacuation
• Built-in solenoid valve — prevents oil contamination on sudden power loss
• 3 inlet ports: 1/4", 3/8" SAE and 1/2" ACME — manifold valve isolates pump during leak testing
• Gas ballast valve — reduces oil contamination risk in high-moisture environments
• 1 HP thermally protected motor — 1440 RPM, 220V 50/60Hz
• Large oil sight glass with max/min indicator
• Easily removable vapour discharge/oil fill port
• Cooling fins and a high-volume fan for extended operation
• Lightweight reinforced base for stable positioning
