Choosing an oil-free air compressor over an oil-lubricated air compressor.
Oil-lubricated air compressors use oil in the compression stage for sealing, lubrication and cooling. During operation, lubricating oil can be carried over into the compressed air system. A thorough understanding of compressed air quality and testing standards is therefore indispensable when designing your system to achieve the purity levels your application requires. Which standards you should apply will depend on the specific contaminants you aim to remove and the purification equipment you will rely on to do so.
The International Organization for Standardization (ISO) sets these standards and the ISO quality classes of air will help you determine whether or not you need an oil-free compressor. If your air quality requirements and oil carryover concerns dictate oil-free, the investment in an oil-free or oil-less air compressor will deliver the product quality that is demanded and valuable peace-of-mind.
When evaluating oil-free air compressors, you will be presented with options such as single-stage, two-stage, water-injected single-stage, scroll and centrifugal technology choices. These technologies do overlap in certain horsepower ranges, but typically only two to three will be available for a given horsepower or flow size. Determining the size of oil-free air compressor you need first will help in your decision process.
