SIERRA - Superior Technology
To fit the needs of your compressed air system, there is a choice of air cooled or water cooled compressed air packages - both designed for maximum performance.
The heart of the Sierra oil free rotary screw air compressor is our superior two stage compression module.
It makes the Sierra one of the toughest machines in the business.
Stainless steel is used for critical sealing components as well as for 
the high pressure rotor set.
Combined with the use of the UltraCoat process for the rotors and housing bores, this module design offers double protection against wear and the effects of corrosion.
Precision machine rotors, high quality bearings and meticulous gearing maintains an exact alignment of the rotors, ensuring years of reliable efficient service.
The Sierra compressor incorporates a durable high efficiency IEC motor for 50 Hz models or a certified NEMA motor for 60 Hz models.
The Star-Delta Starter gives the compressor a controlled, cushioned start, eliminating current surges and extending component life for increased system reliability.
The combination of an inlet sound box and a low sound enclosure design, keeps sound levels at a minimum.
The Sierra's packaging features are intended for optimum customer benefit for locations world-wide - they are designed to operate in 46°C ambient conditions.
Total control at your fingertips with an Intellisys controller providing quick comprehensive access to your compressed air system.
Whether you need 8 hours of continuous duty compressed air or an intermittent supply over a 24 hour period - Intellisys puts you in complete control.
