Mastercool 90063-2V-220SVBL — Black Series 2-Stage Vacuum Pump 70 lit/min with Solenoid Valve

Premium Protection: Two-Stage Performance with Solenoid Valve Safety

The Mastercool 90063-2V-220SVBL combines professional two-stage vacuum performance with critical solenoid valve protection. This premium version of the 90063 automatically prevents oil backflow during power failures or sudden shutdowns, protecting your A/C systems from contamination. With 70 litres per minute displacement and 15-micron capability, it's the smart choice for technicians who demand both performance and protection.

Solenoid Valve Protection: Your Insurance Against Contamination

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. This critical safety feature protects your work and prevents costly system contamination that can damage compressors and require complete refrigerant replacement.

Why This Matters: Without solenoid valve protection, a sudden power cut or accidental shutdown can allow pump oil to flow back into the freshly evacuated system, contaminating the refrigerant and potentially damaging the compressor. The SVBL's automatic protection eliminates this risk entirely.

Integrated Analogue Vacuum Gauge

The built-in analogue vacuum gauge provides immediate visual confirmation of vacuum level and stability over time. Monitor your evacuation progress at a glance without connecting external gauges, and verify that the system holds vacuum after pump shutdown — essential for leak testing and quality assurance.

Two-Stage Performance for Deep Vacuum

The two-stage design achieves 15 microns ultimate vacuum — essential for modern refrigerants and ensuring moisture-free systems. With 70 litres per minute displacement at 50Hz, it handles residential and light commercial jobs efficiently whilst remaining compact and portable.

The Premium Choice for Professional Technicians

The 90063-2V-220SVBL represents the pinnacle of mid-range vacuum pump design. You get professional two-stage performance with 15-micron capability, plus the critical protection of a solenoid valve and the convenience of an integrated vacuum gauge. This is the pump for technicians who understand that preventing contamination is just as important as achieving deep vacuum.

Perfect for:

• Professional HVAC technicians requiring contamination protection
• Mobile service work with power interruption risk
• High-value residential and commercial installations
• R410A and modern refrigerant systems
• Quality-focused businesses with strict service standards
• Job sites with unstable power supply
• Any application where oil backflow protection is critical

SVBL vs Standard: Worth the Investment?

The solenoid valve adds approximately £100-150 to the cost of the standard 90063-2V-220-BL. Consider this: a single contamination incident requiring refrigerant replacement and system flushing can cost far more in materials, labour, and reputation. The SVBL pays for itself the first time it prevents contamination during an unexpected power failure.
