How can we help you?
We know that in many industries, air purity is critical. Even the tiniest drop of oil can cause product spoilage or damage production equipment. That is why it is always important to consider your production process and end product when choosing an air compressor. More and more businesses are looking to oil free air compressors as a reputable source of providing clean compressed air.
Oil free compressors use various technologies that bypass the need for oil. In oil lubricated compressors, oil is used in the compression chamber to cool and seal the air. In an oil-free compressor, no matter what type of technology is being used, no oil will ever be used in the compression chamber. This eliminates the risk of contamination and ensures 100% air purity!
Aside from a completely risk free operation, some of the core benefits of choosing an oil-free compressor are:
Low cost of ownership
Save on the costs of oil replacements as well as equipment used to clean and separate oil from air such as oil separators, filtration equipment and condensate treatment.
Oil free compressors are more compliant with international environmental regulations than lubricated systems, making for an environmentally conscious compressor choice.
No oil and less moving parts means less maintenance and fewer areas for problems to occur.
ISO Certified Air Quality
All of our air compressors meet either ISO Class 1 or ISO Class 0 air purity.
Quiet by design
Due to the limited amount of moving parts, they produce less noise pollution and less vibration.

Oil free technologies are popular in many industries where compressed air needs to meet stringent health and safety and air quality standards. Oil free designs are perfect for businesses who need to ensure no product spoilage occurs due to contaminated air output.
Some industries and applications where dry compressors provide a wealth of benefits and are often used include:
Food and Beverage
When it comes to food safety, health and safety is extremely important. There are rigorous processes in place to ensure that the food we eat is safe, healthy and tasty! Contaminated air could cause product spoilage which is a health risk for the consumer and could cause irreparable damage to a company brand.
Oil free compressors can safely be used for product handling, transportation, food filling machines, air knives for cutting or peeling food products and for vacuum packaging goods as well as many other uses within this diverse sector.
Within the drugs and pharmaceutical industry, quality and safety are strictly adhered to. Any products that reach the market must be rigorously tested to ensure they are safe for consumption. With so many people relying on products from the pharmaceutical industry, clean air is critical for this industry.
Businesses within this sector rely on clean compressed air for a variety of uses including fermentation in antibiotic production, aeration for oxidation processes, tablet production and packaging and bottling of medications.
Toxic chemical and unstable gases will often be part of the process production within the chemical industry. In hazardous processes oil free compressors will help to eliminate the risk of explosions and process disruption. They will also increase product purity resulting in better processes, less waste and increased safety for those relying on the products. Typical uses of compressed air within the chemical industry include process air, control valves and cylinders, material handling as well as air curtains and product drying.
A lot of work goes into producing fabrics with elegant designs and intricate details. Contaminated air could cause damage to materials resulting in costly repairs and maintenance or worse, product wastage. Oil free compressors are used within the textile industry for intricate tasks such as air-jet weaving and spinning, texturising and pneumatic transport.
Oil and Gas
Process reliability is essential within the oil and gas industry where hazardous chemicals are often used. Popular uses within this sector include nitrogen generation, buffer air, control/ instrument air and process operations for sulphur removal, catalyst regeneration and process heaters, to name a few.
High quality vehicles rely on high quality compressed air. Impure air can result in damage to a product finish and may even require expensive repair work to fix. Whether compressed air is used for tyre inflation or more complex uses, such as air operated robots, pure air provides the best results. Typical uses within this industry include product finishing with spray paint, pneumatic tools, plasma cutting and welding as well as cleaning.
For smooth running control systems, ultra-clean conditions need to be maintained. Furthermore, where expensive electronic equipment is concerned, there can be no room for error or risk. Compressed air is often used in electronics for actuating valves and tools within control systems as well as moving and placing electrical components. Additional common uses include cleaning PCB boards and in the production of electrical equipment.
