Mastercool 90067-220-SV — Professional 2-Stage Vacuum Pump 178 lit/min with Solenoid Valve 1/2 HP

The Ultimate: Maximum Capacity with Elite Protection

The Mastercool 90067-220-SV represents the absolute pinnacle of professional vacuum pump design. Combining flagship 178 litres per minute capacity with solenoid valve protection and elite ball bearing construction, this is the ultimate choice for professionals who demand maximum performance, maximum protection, and maximum durability. When only the best will do, the 90067-SV delivers.

Solenoid Valve Protection: Critical for Flagship Capacity

The integrated solenoid valve automatically closes when the pump stops, preventing oil from flowing back into the A/C system during power failures, accidental shutdowns, or when switching off the pump. On the flagship 90067 with its massive 708ml oil reservoir, this protection is absolutely essential — a power failure without solenoid protection could push significant amounts of oil back into your system.

Why This Matters on the Flagship: The 90067 holds 708ml of oil — nearly 50% more than the 90065 and almost three times the 90063. A power failure on a pump this size without solenoid protection could contaminate an entire large commercial system, requiring complete refrigerant replacement and system flushing. The SV model eliminates this risk entirely.

Elite Ball Bearing Design for Maximum Durability

The 90067-220-SV features elite ball bearing construction throughout — the ultimate in durability and longevity. Ball bearings reduce friction, run significantly cooler, and last far longer than standard sleeve bearings. On a flagship pump designed for continuous professional use on large systems, this premium construction is essential for long-term reliability.

Maximum Capacity Two-Stage Performance

With 178 litres per minute displacement at 50Hz, the 90067-SV is the most powerful pump in the professional range. The robust 1/2 HP motor ensures quick, easy start-up even in cold conditions, whilst the two-stage design achieves 25 microns ultimate vacuum. Perfect for systems with 2.25 kg charge capacity and above.
