Why Two-Stage Vacuum Pumps?
Two-stage vacuum pumps provide superior performance compared to single-stage designs:
- Deeper Vacuum: Achieves 15 microns vs 50-100 microns for single-stage pumps
- Faster Evacuation: Removes air and moisture more quickly
- Better Moisture Removal: Lower vacuum levels ensure thorough dehydration
- Professional Standard: Required for modern refrigerants and A/C systems
- System Protection: Thorough evacuation prevents compressor damage
- Warranty Compliance: Many manufacturers require deep vacuum for warranty validity
Applications
- HVAC/R system evacuation and dehydration
- Automotive A/C system service
- Commercial refrigeration installation and maintenance
- Heat pump installation
- Refrigerant recovery system evacuation
- Large capacity A/C systems
- Workshop and mobile service operations
- Professional HVAC/R contractors

- Workshop and service centres
- Mobile service operations
- Fleet maintenance facilities
- Technicians requiring deep vacuum capability
- High-volume service operations
Operation
- Check oil level in sight glass before operation (max/min indicator)
- Connect vacuum pump to system via appropriate inlet port (1/4", 3/8" SAE, or 1/2" ACME)
- Ensure all system valves are open for evacuation
- Start vacuum pump using on/off rocker switch
- Open gas ballast valve if evacuating moist systems
- Continue evacuation until system reaches target vacuum (typically 500 microns or lower)
- Use manifold valve to isolate pump and monitor for vacuum decay (leak test)
- If vacuum holds, system is ready for charging
- Close gas ballast valve and shut down pump
Maintenance
- Oil Changes: Change oil regularly based on usage (every 10-20 hours for heavy use)
- Oil Level: Check sight glass before each use (max/min indicator)
- Oil Condition: Replace oil if it appears milky or contaminated
- Oil Capacity: 18 oz / 536 ml
- Gas Ballast: Use when evacuating moist systems to protect oil
- Oil Drain: Use easily accessible drain valve for quick changes
- Storage: Store in clean, dry environment
- Connections: Keep inlet and exhaust ports clean and free from debris
- Thermal Protection: Allow motor to cool if thermal protection activates
Achieving Deep Vacuum
To achieve and maintain deep vacuum (15 microns):
- Use properly sized vacuum hoses (3/8" or larger recommended)
- Keep hose lengths as short as practical
- Ensure all connections are tight and leak-free
- Use a micron gauge to verify vacuum level
- Allow sufficient evacuation time for system size
- Maintain clean, fresh vacuum pump oil
- Use gas ballast valve when evacuating moist systems
- Monitor oil level in sight glass regularly
Why Deep Vacuum Matters
Achieving deep vacuum (below 500 microns) is essential for modern HVAC/R systems:
- Moisture Removal: Water boils at lower temperatures under vacuum, allowing thorough dehydration
- System Protection: Moisture causes acid formation, corrosion, and compressor damage
- Performance: Air and moisture reduce system efficiency and cooling capacity
- Refrigerant Purity: Non-condensables contaminate refrigerant and reduce performance
- Warranty Compliance: Many manufacturers require deep vacuum for warranty validity
- Professional Standard: Industry best practice for quality installations
Dual Voltage Capability
The 90612-2V-110-BL features dual voltage capability (110V/220V), providing flexibility for:
- International use in different voltage regions
- Workshop environments with multiple power sources
- Mobile service operations with varying power availability
- Future-proofing for workshop changes
Supplied with 110V cable. Voltage selection typically via internal switch - consult user manual for switching procedure.
Manifold Valve System
The integrated manifold valve allows you to isolate the pump from the system during leak testing, enabling accurate vacuum decay monitoring without shutting down the pump. Three inlet ports (1/4" SAE, 3/8" SAE, 1/2" ACME) provide maximum connection flexibility for different hose sizes and applications.
Professional Quality: Mastercool Black Series vacuum pumps are built to professional standards for reliable, high-performance evacuation in demanding HVAC/R and automotive workshop environments. Two-stage design delivers deep vacuum capability essential for modern refrigerant systems. Stands up to the most gruelling conditions.
