CompAir offers a wide range of oil-free compressor solutions, each one built to achieve 100% air purity that meets the most stringent quality standards. We know that in many industries, air purity is critical. Even the tiniest drop of oil can cause product spoilage or damage production equipment. When we say these products are 100% oil free, we are serious. Whether your business is big or small, we have the solution in our range of oil-free compressors. The following models are oil-free and capable of providing the atmosphere essential for clean air critical applications.


CompAir is always improving the best products to be even better and more cutting edge. Ultima™ is CompAir’s groundbreaking oil-free PureAir compressor with a unique design. It is a brand new compressor range and it utilises a low pressure and high pressure dry screw airend. Each airend is individually driven by a variable speed, permanent magnet synchronous motor, offering exceptional levels of efficiency versus traditional oil-free technology.

Considering that the highest cost in the lifecycle of a compressor is the energy to run it, the unique design of Ultima has allowed us to combine the ultimate performance with the ultimate efficiency, and still deliver a footprint 37% smaller than a conventional two-stage oil-free compressor. This allows easy installation in the smallest possible space – more than a benefit where space is limited – it is a real property cost saving.


CompAir has launched a completely new range of high efficiency, oil-free two-stage rotary screw compressors to further enhance its successful and award winning D-Series. With the addition of ten new models, the D-Series now covers a wide flow range from 8.9 to 51.8 m3/min. The D75 – D315 models are fixed speed and the D110RS – D315RS models are regulated speed.
>> Air purity that meets the most stringent hygienic standards
>> Award-winning Class 0 Certified oil & silicone-free compressors
>> High efficiency, low pressure losses, low temperature operation & economical control


The DH series contains absolutely no oil anywhere in the compressor and has been certified ISO 8573-1 Class Zero (2010) and silicone free.
>> Single-stage, direct-driven compression element maximises efficiency and minimises maintenance
>> High quality water injection lubricates, cools and seals the compression process, maximising efficiency
>> No gearbox means no need for associated oil lubrication
>> Low bearing loads and low speeds mean sealed-for-life bearings can be used, requiring no oil lubrication
>> Regulated speed technology available to reduce energy costs
>> Comprehensive control ensures safe and reliable operation and includes remote communication capability
>> Fully packaged and silenced enclosure reduces noise and simplifies installation


CompAir’s oil-free two-stage variable speed centrifugal compressors are the best compressed air insurance you can get. Air purity is critical for many applications where even the smallest drop of oil can cause product spoilage, or damage the production equipment. Quantima is a completely oil-free compressor. Using Quantima eliminates all possible risks associated with oil and silicone contamination. It is designed and manufactured to give compressed air users complete peace of mind and provides 100% air purity, certified ISO 8573-1 (2010) Class 0 and silicone-free!

The CompAir Quantima series delivers significant benefits over traditional technology. Offering outstanding energy efficiency, reliability and low environmental impact, Quantima also offers low noise levels at 69 db(A) and a physical footprint around 25% smaller than any comparable product in the market.


CompAir’s new oil free S-series scroll compressor has set a new standard in compressed air delivery. Not only does this scroll compressor series meet industry standards, but this technology reduces the costs of ownership because there is no need for oil filter replacements, oil condensate treatment and energy to combat the pressure loss caused by filtration. It is 100% oil and silicone contaminant free.
>> Premium 100% Certified Class 0 Oil & Silicone-Free Rotary Scroll Compressors
>> Reduced cost of ownership – no oil filter, no condensate treatment, no filters
>> Maximum flexibility from modular design & low maintenance due to fewer moving parts
