There are different air purity classes that compressed air can fall into according to the International Organisation for Standardisation (IS0). It is important to consider if your business requires a specific class of air before you choose which type of compressor to purchase. Air compressors can be specified to meet with an ISO class to ensure the product meets your exact expectations.
Food and beverage industries, as well as pharmaceutical and chemical, will often require ISO Class 0 air quality. This is the cleanest standard of compressed air possible and requires extremely high levels of air purity.
If clean air is required for your application, an oil-free compressor will always be the most efficient choice. Although upfront costs may be more than a traditional lubricated compressor, you will benefit from the assurance of always being able to guarantee a clean output of contaminant and silicone-free air. All of CompAir’s oil free compressors are certified as either ISO Class 1 or ISO Class 0 air purity, offering our customers the cleanest solution.
If your compressed air installation will be for general use and not require Class 0 clean air, then a lubricated compressor will be the more economical choice for you. Lubricated compressors are extremely popular and are the most common type of compressor in use within industrial sectors. They are robust, reliable and high performing machines. Plus, downstream equipment such as filters and separators can be used to clean compressed air output effectively, removing contamination and providing clean air suitable for many purposes.
