Compressed Air Filter Elements

The compressed air in compressor systems is sent to the air tank to be stored by passing through various filtration stages. The humidity in the air exposed to pressure in the rotor part of the compressor and then in the air tank can turn into water particles at a level that can damage the system. Unfiltered water particles cause corrosion, especially in systems where compressed air is used, resulting in a decrease in system efficiency and an increase in maintenance costs. In-Line filters with special filtration properties and low micron values produced by Filsan Filter are used in order to prevent damages that may occur from such undesirable situations, to increase system efficiency and to minimize maintenance costs that may arise from moisture.

Filter Element Types

AUX replacement filter elements which are the productions of wide research and special design, can be utilized in many areas of industry for different applications. These type of filter elements are installed in compressor dryers as filter units made of one or more filters in succession.

In the first and the second stages of filtration solid and liquid particules of 1 to 5 microns are retended successivelly at very low pressure losses.

The third stage elements are for high pressures and filters the particules of down to 0.01 micron. Another variety of these filter elements is the ones contain active carbon. By this way, it removes odor and oil vapor particles down to 0,003 ppm. These highly efficient elements are designed to be used in applications of medical and food precessing. Upon request of compressed air manufacturers, special designs or enhanced types of filter elements may also be manufactured.

Particulate compressed air filters are used to remove dust and particles from the air. The air stored in the air tank, before being sent to the dryer system, passes through a filter with a filtration capability of up to 3 microns as a pre-filter, and the pollutants that may be in the air are filtered before they reach the coalescing filters.

Coalescing filters are used to capture oil and/or moisture that is suspended in the compressed air in very tiny droplets. The air that comes from the pre/particle filters, free of pollutants that can reduce the life and efficiency of the coalescing filters, is filtered down to 1 micron in the coalescing inlet (Blue) filter and sent to the dryer system. By the special gases in the dryer system, the moisture in the air is condensed by cooling and it is filtered in the Output (Red) coalescing filter, which has a sensitive filtration feature up to 0.01 micron, and is brought to a humidity level that will not harm the system.

Activated carbon filters will remove odors and vapors.  Filsan’s Activated carbon filters are; filters used to prevent gas molecules in the air drawn from outside in compressor systems and cause bad odor. Activated carbon filters are important in compressor systems in terms of ensuring that the odor in the dehumidified air or any gas molecule that may be harmful is given to the system in a purified manner after the in-line filters. These filters perform the filtration process as a result of the harmful gas molecules in the air sticking to the active carbon in the structure of the filters.
