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.
SPIRALAIR oil free compressors
The SPIRALAIR range offer high level performances as well as first-rate efficiency and quality. With the oil-free compressors, you will not only benefit from high quality air, but you will also preserve our environment.
Industries such as pharmaceuticals, food and beverage, electronics and textiles cannot risk any chance of oil contamination in their processes. Therefore, it is essential that the compressed air is 100% oil-free. The standard is ISO 8573-1 (2010) certification, in which Class Zero represents the highest air purity. It is the only way to ensure oil-free air for your critical processes and with it peace of mind. Outstanding reliability, low maintenance and operating costs make oil-free compressors a sound investment.

Class 0: eliminating any risk
Class 0 represents the best air quality possible. In critical environments it is essential that the compressed air is 100% oil-free. Contamination by even the smallest quantities of oil can cause costly production downtime and product spoilage, resulting in product recalls and loss of reputation.
Scroll technology: how does it work?
Air compression is achieved through the orbital motion of two spirals. One being static, the second mobile, their interaction pulls the air into the compression chamber. In a regular and continuous way, the mobile spiral compresses the air through a reduction of the volume. The air flow is directed to the center of the spiral after which it is cooled. As the spirals never make any contact, this compression process does not require any lubrication. Consequently, Spiralair compressors guarantee 100% oil-free compressed air.
Variable Air Delivery
The SPR 10-30 units are equipped with multiple scroll modules. The units utilize Variable Air Delivery technology which controls the required number of modules depending on your air demand.
Hence, the Spiralair Multi can adjust to demand fluctuations. The intelligent controller prevents simultaneous start of the modules and ensures a very narrow pressure band is maintained.
This optimizes the efficiency of the compressor and guarantees a very stable system pressure
Control & monitoring
The Spiralair range comes with a wide variety of control and monitoring features that allow you to increase your compressor’s efficiency and reliability. The SPR 2-8 are equipped with an Electro Pneumatic Control which automatically starts/stops the unit when the required working pressure is reached. The SPR 10-30 come with a Graphic Controller.
Intelligent Graphic Controller (SPR 10-30)
The multiple control and monitoring features of the controller on the SPR 10-30 units dramatically increases the compressor’s efficiency and reliability. Efficiency is maximized by controlling the main drive motor and regulating the system pressure within a pre-defined and narrow pressure band.
Control and monitoring features:
• Warning indications. • Graphical indication service plan. • Integrated sequence for up to 6 compressors limiting the energy consumption and equalizing running hours across your whole system. • Online visualization of running conditions.
