Variable-speed Air Compressors

Class 0 ISO 8573.1 Lifetime Guarantee

PneuTech's RSCRV and RSCRPM series of variable-speed drive (VSD) rotary screw compressors have achieved well-deserved renown in the marketplace for their unparalleled performance, energy-saving efficiencies and long-term reliability. The flagship permanent magnet (PM) screw compressor series brings a new generation of power-saving benefits to the VSD compressor group, with cutting-edge and proven engineering processes.

Variable speed air compressors

Features

Variable-speed technology automatically adjusts motor speed to match your compressed air demand, delivering energy savings up to 40% with RSCRV models and up to 60% with permanent magnet RSCRPM units. When demand drops, the intelligent standby function maintains system pressure with minimal energy draw.

Monitor pressure, temperature and current in real time through the intuitive interface. Track service cycles, identify faults and analyse duty cycles. Connect multiple units for centralised monitoring or integrate with PneuTech's Master Controller to operate up to eight compressors in sequence.

Oversized air intake filtration, three-stage oil cleansing and a 30% larger after-cooler handle ambient temperatures up to 45°C. Solid steel air and oil pipelines eliminate bursting risks. Unlimited motor starts per hour without degradation on PM models.

Double-sized air ends spinning at less than half the RPM of belt-driven models reduce wear significantly. High-efficiency rotor profiles paired with Mepps 2 drive motors feature class-F insulation for extreme durability. Direct-coupled KTR transmission eliminates belts and minimises power loss.

Frequently Asked Questions

Do you offer 24/7 support, 365 days per year?

Yes. When most teams sleep or are on holiday, our experienced team of professional support technicians works around the clock to ensure your factory is covered, whatever the time of day.

What's the difference between RSCRV and RSCRPM models?

RSCRPM units use permanent magnet motors offering superior efficiency and faster response times, ideal for highly variable demand. RSCRV models use high-efficiency induction motors with VSD controls. Both significantly outperform fixed-speed compressors.

How much can I actually save with variable-speed technology?

Savings depend on your demand profile. Operations with fluctuating air requirements typically see 30-40% energy reductions with RSCRV models, whilst PM series can achieve 50-60% savings. We conduct free site assessments to calculate your specific potential.

Do variable-speed compressors require special installation?
No special requirements beyond standard rotary screw compressor installation. You'll need adequate ventilation, appropriate electrical supply and room for maintenance access. Our technical team handles site assessments and installation planning.
