Damages to inside of air receiver/piping system and excess water problems due to bad air quality

When atmospheric air goes through a compressor, the air volume is reduced but the air still contains the same amount of impurities and water as the original air volume.

TMC offers complete compressed air systems including dryers and filters to achieve the highest air quality. Proper filtration is the only way to obtain oil-free air.

A compressor installed on board 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.

 

Economic benefits of an oil-lubricated compressor

To determine the total economy of an oil-free compressor versus an oil-lubricated compressor consider the following:

Investment costs

Considerably lower for an oil-lubricated compressor.

Overhaul intervals

Considerably longer for an oil-lubricated compressor.

Service

Considerably simpler and easier for an oil-lubricated compressor.

Reliability

The reliability of oil-lubricated TMC compressors is well established. Reliability is particularly impressive for the high ambient temperatures in which an oil-free compressor suffers.
