Who It's For
- Factories and manufacturing plants needing reliable compressed air supply
- Operations upgrading from ageing or inefficient piston compressors
- Facilities with variable air demand looking to reduce energy costs
- Businesses wanting a single supplier for equipment, installation, and ongoing maintenance
Fixed Speed
HB Series — Reliable, Constant-Output Performance
The HB Series is a straightforward, dependable direct-driven rotary screw compressor built for facilities with steady, consistent air demand. It delivers reliable output without complexity — ideal for production environments where uptime is the priority.
-
Rotary Screw Airend
High-efficiency twin-screw airend for continuous duty operation with minimal pulsation and vibration.
-
Fixed-Speed Drive Motor
Constant-speed operation delivers stable, predictable compressed air output suited to steady demand.
-
Integrated Oil Separation System
Built-in oil separator and filtration minimises oil carryover and keeps downstream equipment clean.
-
Simple, Reliable Controls
Straightforward control panel with pressure setpoint, run/stop, and basic fault indication — easy to operate and maintain.
-
Long Service Intervals
Designed for extended maintenance intervals to reduce servicing frequency and keep operating costs low.
-
Compact, Self-Contained Package
Compressor, motor, coolers, and separator housed in a single acoustic enclosure — minimal installation footprint.
-
Low Noise Operation
Acoustic canopy and vibration-isolated mounting keep noise levels acceptable for workshop and factory environments.
-
Suitable for Continuous Duty
Rated for prolonged operation without thermal cutout — suited to production lines that need constant air supply throughout the working day.
Variable Speed Drive
PMC Series — Permanent Magnet VSD, Matched to Demand
The PMC Series uses a high-efficiency IE4 permanent magnet synchronous motor with variable speed drive to match compressor output precisely to actual air demand — eliminating energy waste during low-demand periods and reducing electricity costs by over 20% compared to fixed-speed units.
-
Permanent Magnet Variable Speed Drive
IE4 synchronous motor speed continuously adjusts to match actual air consumption — no energy wasted on load/unload cycling.
-
Over 20% Energy Savings
Significant reduction in electricity consumption versus fixed-speed alternatives, especially in facilities with variable air demand.
-
Soft-Start Technology
Gradual motor acceleration reduces electrical stress and mechanical shock on startup — extends motor and airend life.
-
Stable System Pressure
Maintains tighter pressure band than fixed-speed units, reducing pressure drops and improving quality for sensitive downstream processes.
-
Smart Controller with Monitoring
Built-in controller displays real-time operating data — pressure, temperature, power draw, and service intervals — for informed maintenance decisions.
-
Reduced Noise at Partial Load
Motor and fan speed reduce proportionally at lower demand, making the PMC Series noticeably quieter during off-peak hours.
-
Extended Component Life
Fewer start-stop cycles and lower average operating temperatures result in reduced wear on bearings, seals, and the airend.
-
Ideal for Variable Demand Profiles
Best suited to facilities where compressed air usage fluctuates across shifts, production cycles, or seasons.
