Suction filter
Function; filtering out impurities of the cooling system is prevented these impurities reaches the compressor. As the filter has only one direction, it must always be installed at points where there are no reversing valves, such as when fired, do change the direction of fluid flow and thereby cause problems to the filter and also the whole system. To avoid problems, the filter must be installed as close as possible to the compressor, because there will never be reversing valve.
