    Zero Risks of Oil Contamination

    SpiralAIR SPR oil-free scroll compressors comply with ISO 8573-1 CLASS 0 (2010) certification, providing 100% oil-free air for critical applications such as medical, pharmaceutical, dental, R&D, food & beverage, wine and brewery. SpiralAIR scroll compressors are designed with fewer moving parts, which means less wear and tear, less noise, higher efficiency, higher reliability and longer machine life.

    Multi = Variable Air Delivery

    The SPR 20 Multi comprises of 4 scroll modules, which are controlled by an intelligent controller to operate only when required. The air delivery can be varied according to the fluctuation of air demand, resulting in high energy efficiency and stable system pressure.

    How Scroll Technology Works

    Air compression is achieved through the orbital motion of two spirals. One being static, the second mobile, this movement pulls the air into the compression chamber. In a regular and continuous way, the mobile spiral compresses the air through a reduction of volume. The air flow is directed to the centre of the spiral. As the spirals never make any contact with each other, this compression process does not require any lubrication, so the SpiralAIR is 100% oil-free.
