The need for filtering compressed air to make it usable is vast. Compressed air is not usable as a utility directly from the compressor source. It needs to be prepared and cleaned by a compressed air filter or dryer to various levels of cleanliness, depending on the task at hand. Spray painting, blasting, pneumatic tool preservation, surface preparation, pneumatic controller protection, and worker safety are just a few of the needs for clean, compressed air.
In today’s workplace, compressed air is the other utility that must be prepared to a level of cleanliness necessary for the task at hand. It seems to be the utility that is most often used and normally given the least attention or thought.

Often compressed air is overlooked and misunderstood. The use of compressed air is an ever increasing demand. That said, compressing air and sending it downstream through a system of plumbed lines is not a usable commodity. When we compress the ambient air, we squeeze the water moisture that is held in the air, into the tank where it becomes liquid. This liquid mixes with the oil used to lubricate the compressor. Then this oil/water moisture travels downstream and picks up contamination from the lines and hoses, which is all then deposited into the tool being used or the object subjected to the compressed air stream. All of these issues are not acceptable.
