Desiccant filters, also called air Dryer Filters, convert air into water during compression, which are normally contained in the air and are too small to be seen. Moisture and water are always contained in the compressed air, which is disposed of outside the system when it is transported to the compressed air system.

Air dryer filters, known as compressed air dryer, have an effect on the efficiency reducer if the moisture is not disposed of in the system, and this is an undesirable situation. Failure to dispose of moisture from the system results in a major loss in production, resulting in additional maintenance costs, increasing the cost.
