There is a growing need for additional point-of-use filtration. In spite of this, most operators only install a single filter/regulator, which helps remove particulates but does not remove water or oil.A remedy for this is to place a multi-stage filtration system including a coalescing filter to remove oil vapor as close as possible to the equipment using instrument air or instrument gas. This protects sensitive instruments and keeps critical equipment operating as intended.Having poor air or gas quality can cause equipment failure and shutdowns. Filtering instrument air and gas can prevent such problems, but having a filter set at the compressor may not be enough.The presence of particulates, water, and oil in the stream of instrument air or instrument gas can cause a lot of problems with downstream equipment. Contamination causes 90% of valve failures. Oil contamination can cause hydraulic lock between the spool and sleeve, causing positioners to fail. If oil reaches the dryer media it causes immediate failure. Moreover, oil or water can cause inaccurate readings from analytical equipment, resulting in shutdown and expensive maintenance.One way to prevent these failures is to fit a single filter at the air compressor outlet or instrument gas supply source. However, this does not protect against contaminants introduced after the air or gas leaves the source. The reason behind this is that simple filter/regulators remove little water and no oil. Also, the aggressiveness of air system contaminants is magnified under compression. Finally, a "one-size fits all" filter at the source is inadequate for specialized equipment requiring finer filtration and oil removal.A multi-stage filtration system should meet an application's specific requirements and be installed as close as possible to the equipment being powered. With proper care and maintenance, as well as the use of quality air compressors, cost-saving and long lasting systems are assured.
