Mastercool 90063-2V-220-BL — Black Series 2-Stage Vacuum Pump 70 lit/min 50Hz 1/3 HP

The Perfect Balance: Professional Performance at Mid-Range Value

The Mastercool 90063-2V-220-BL delivers the sweet spot between economy and premium performance. This two-stage vacuum pump combines professional-grade 15-micron deep vacuum capability with a mid-range price point, making it the ideal choice for technicians who need serious performance without the cost of the larger 90066 series.

Two-Stage Performance for Deep Vacuum

Unlike single-stage pumps that struggle to reach deep vacuum levels, the 90063's two-stage design achieves 15 microns — essential for modern refrigerants and ensuring moisture-free systems. With 70 litres per minute displacement at 50Hz, it handles residential and light commercial jobs with ease whilst remaining compact and portable.

Black Series Engineering Throughout

• Refined Cartridge Machining — Improved surface finish extends pump life and reduces wear
• Expanded Internal Oil Path — Minimises friction and heat buildup during operation
• Upgraded Seals — Ensures maximum vacuum performance down to 15 microns
• U.S. Designed and Tested — American engineering with proven reliability
• Check Valve Protection — Prevents oil back-flow into the system

Professional Features for Demanding Work

• Gas Ballast Valve — Helps prevent oil contamination caused by high moisture content in the system
• Manifold Valve — Isolates pump from the system when testing for leaks, includes 3 inlet ports (1/4" SAE, 3/8" SAE, 1/2" ACME)
• Advanced Cooling System — High-volume fan directs cool air to motor and pump, whilst cooling fins maintain optimal temperature during extended operation
• Easy Maintenance — Removable vapour discharge/oil fill port and accessible drain valve simplify servicing (250ml oil capacity)
• Oil Level Monitoring — Large sight glass with max/min indicators for easy visual checks
• Thermal Protection — Motor protection with convenient on/off rocker switch

Built for Field Reliability

• Portable Design — Easy-grip handle and lightweight reinforced base (7.25 kg) for stable field positioning
• Compact Footprint — 27 x 15 x 25 cm dimensions fit easily in your vehicle

Why Choose Two-Stage?

Two-stage vacuum pumps are essential for:

• Modern Refrigerants — R410A, R32, and other HFCs require deep vacuum (below 500 microns)
• Moisture Removal — 15-micron capability ensures complete moisture evacuation
• System Longevity — Proper evacuation prevents compressor damage and system contamination
• Professional Standards — Meets industry best practices for refrigeration system service
• Faster Evacuation — Reaches target vacuum levels more quickly than single-stage pumps

The Mid-Range Advantage

The 90063 sits perfectly between the economy 90059 single-stage and the premium 90066 high-capacity pump. You get professional two-stage performance with 15-micron capability, gas ballast valve, and manifold isolation — all the features you need for quality work — without paying for the extra capacity of the larger pump.

Perfect for:

• Residential air conditioning installation and service
• Light commercial HVAC maintenance
• Heat pump installations requiring deep vacuum
• Mobile technicians needing portable two-stage performance
• R410A and modern refrigerant systems
• Professional technicians who need 15-micron capability without the bulk

Smart Choice for Professional Technicians

The 90063-2V-220-BL proves you don't need the largest pump to do professional work. With two-stage performance, 15-micron capability, gas ballast valve, and manifold isolation, it delivers everything required for quality refrigeration service in a compact, affordable package. This is the pump for technicians who understand that proper evacuation is critical but don't need the extra capacity (and cost) of the 90066 series.
