Filters

Pre Filter:

Every dryer should be equipped with pre-filter to protect the desiccant from free water contamination, dust, scales, etc., from compressed air supply. This assures top efficiency and longer desiccant life.

Zero Oil Filter:

Oil from the compressor's crank case will be passed on to the line with the compressed air. This will severely effect the life of the desiccant. To enhance, oil particles are removed in this filter upto 1 micron rating.

After filter:

This is provided after the dryer to remove the desiccant dust carried over to the equipment.
