Proper filtration is the only way to obtain oil-free air.
A compressor installed onboard a ship will compress the ambient air, which normally contains various impurities and up to 1 mg/m3 of oil. Due to the high oil content in the ambient air, proper filtration should always be installed downstream to ensure the quality of the air.
It’s a widespread belief that an oil-free compressor (a compressor with no oil in its internal system) produces oil-free air. This is not correct. The impurities from the ambient air will not disappear when the air goes through the oil-free compressor.
An oil-lubricated compressor with proper filtration can easily achieve oil-free air of the highest purity class under ISO 8573.1. An oil-free compressor also needs proper filtration to achieve this. In air systems set up to achieve the highest air quality, oil-lubricated compressors, as supplied by TMC, have many advantages.
The TMC F-Series of compressed air filters provide the exact degree of filtration needed for your application.
The filters are designed to achieve the internationally recognized ISO8573-1 air quality standard. The differential pressure indicator indicates optimum time for element change – maximizing your element investment while minimizing pressure drop.
