Advanced Airend Technology: The innovative η-V rotor design minimises pressure losses and enhances stage efficiency, resulting in a more efficient compressed air system. Combined with a lower gear ratio in the airend, it ensures reliability and reduces maintenance requirements.

Durable Construction: The OF Series is built for long-term stability and reduced wear and tear. Its rigid stainless-steel tubes and special bearings are optimised for 2 stage compressor speeds and temperatures.

Efficient Temperature Control: Available in water-cooled compressor and air-cooled compressor models, the OF Series is optimised for efficient operation across temperatures and conditions, with a focus on maintaining optimal performance and reliability.

Proprietary Cooling Technology: The series features coolers with a water-in-tube system designed for temperature differences of up to 8°C, ensuring the lowest fouling factor and highest thermal efficiency among other two stage compressors.

Cutting-Edge Sealing Mechanisms: The OF Series incorporates non-contact type Visco seals made of bronze and carbon-impregnated stainless steel floating seals, offering superior protection against oil entry into the compression chamber. These seals are axially locked by Belleville springs and radially locked by compressed air, ensuring airtight performance as compared to other two stage compressors.

Precision-Engineered Gears: The helical gears are ground to DIM 4 quality and case-hardened to minimise transmission losses and noise during operation. They are also dynamically balanced to reduce vibrations, optimise loads on bearings, and extend bearing life.
