Description
Direct Drive Ratio 1:1 (15 kW)
RELIABLE / ROBUST / PROVEN
10 years of performance in Australia’s toughest conditions
This 20 HP model combines a low-speed airend with a 1:1 maintenance-free coupling for smoother, more efficient operation. Designed for continuous duty in tough Australian environments, it reduces mechanical losses and vibration, delivering stable air pressure for multi-shift operations. The compact yet rugged design ensures easy installation and service access, while the low-noise enclosure makes it ideal for use in sensitive or shared spaces.
FEATURES:
- 15 kW (20 HP) direct-drive rotary screw
- 8 Bar working pressure (10 Bar / 12.5 Bar variants available)
- 2.3 m³/min (81 CFM) nominal capacity for multiple stations or tools
- 66±3 dBA low-noise enclosure ideal for shop-floor use
- Intelligent Micro Controller with service tracking, alarms, and fault history
- European-sourced major components and large, lockable service panels
- Air Outlet: 3/4″
WHY DIRECT DRIVE?
- True 1:1 coupling between motor and airend eliminates belt losses
- Improved energy efficiency and reduced kW/CFM consumption in real-world operation
- Fewer wear parts = lower maintenance and longer lifespan
- Quieter running with reduced vibration and smoother torque transfer
- Steady pressure output across varying loads and duty cycles
- Lower cost of ownership through reduced energy use and maintenance
MINING FEATURES AVAILABLE
- Weather-proofing and corrosion-resistant options for outdoor installations
- Stainless steel door/frame/base options for demanding environments
- Heavy-duty filtration and external filter mats for high dust load
- Enhanced cabinet sealing to protect from dust and moisture
- Site-specific electrical upgrades and 24 V control
- Ingress-protection (IP) upgrades for drives, fans, and other key components

HIGH QUALITY EUROPEAN MOTOR COMPONENTS
MEPS-compliant industrial motor with SKF bearings front and rear; fitted with greasing nipples for easy service and extended life.
AIREND
Precision-engineered German-made rotor set, paired with SKF bearings and European Teflon oil seals, provides high-efficiency, low-noise compression and ensures stable performance through extended run times.
ELECTRICAL COMPONENTS
Siemens-based starter electrics ensure reliable switching, protection, and long-term durability, with strong service support available across Australia.
TRANSMISSION
The KTR German-made coupling provides a direct 1:1 connection between motor and airend. WVIF high-efficiency shock pads reduce vibration and torque impact, promoting smoother and quieter operation.
OIL SEPARATOR
The oversized separator vessel and elements effectively remove oil with <3 ppm carryover, maintaining air quality while providing a low-pressure drop of <0.02 MPa, enhancing overall efficiency.
SUCTION VALVE
This critical load/unload valve is rated for over 2 million cycles and uses a unique design that eliminates the need to seal gaps fully, reducing common failure points from cup seals and diaphragms.
THERMAL VALVE
Featuring a Hoerbiger thermal valve, the system modulates temperature control by cycling open and shut, ensuring the oil stays at optimal levels for lubrication, sealing, and cooling.
COOLER
The oil and aftercooler system provides high-efficiency cooling in warm environments, regulating operating temperatures to protect critical components and maintain performance.
SOLENOID AND PRESSURE CONTROL
European solenoid valves and pressure sensors are used to handle safe starting, unloading, and protective shutdowns, with reliable operation and simplified troubleshooting.
SEAMLESS STEEL PIPES
Seamless steel air and oil lines with high-quality compression fittings reduce leakage risks and minimize pressure loss while maintaining durability and making servicing easier.
AIR INTAKE FILTRATION
Low-restriction, high-efficiency intake filtration—including Donaldson—ensures cleaner intake air, improving reliability, reducing energy use, and extending the life of the compressor.
Warranty
Standard 2-year warranty – covers the complete compressor (terms and conditions apply)
