Screw compressor MSTS-V series

airelectricstationary

Overview
MAC3's MSTS-V 22–75 kW lubricated two-stage screw compressor series combines bi-stage compression and IE5 permanent-magnet motors to deliver improved efficiency, wide flow range and reliable operation for industrial applications.

Key features

• Power range: 22–75 kW
• Operating pressure: 7.5–10 bar
• Maximum air flow: up to 16.01 m³/min (model dependent)
• Two-stage (bi-stage) screw compression: ~+10% efficiency and flow from optimized dual-stage design

Advantages

• 1. Energy efficiency
  • IE5-class permanent-magnet motor (IPM) for high-efficiency drive
  • Advanced cooling system for stable operation up to 45°C ambient
• 2. Two-stage compression
  • Oil-injected interstage cooling for near-isothermal behavior
  • Lower internal losses for extended service life
• 3. Intuitive control
  • Smartronic Pro touchscreen interface for simplified operation
  • Modbus TCP connectivity for multi-compressor control (up to 4 units)
• 4. Reduced maintenance
  • Extended service intervals up to 8,000 hours with synthetic lubricant
  • Optional extended warranty: 5 years or 40,000 hours (conditions apply)

Designed with industry in mind

• High-efficiency separation system: particle filtration down to <3 mg/m³ for improved air quality
• Variable-speed ventilation (VSD): energy savings and reduced noise
• Compact footprint: space-saving layout and easy installation

Fields of application

• Heavy industry, automotive, power generation, metallurgy
• Construction, woodworking, surface treatment, mining and quarries
• Food, electronics, medical–pharmaceutical and other industrial processes
