COALESCING FILTERS
 
COALESCING FILTERS
INTRODUCTION : The Presence of oil, moisture and dust particles in compressed air is a well know fact for industrial applications. As the technology advanced with induction of sophisticated modern machineries working on compressed air, the usage of recommended quality class of air as per machine manufacture or international Standard Organisation (ISO) or Pneurop recommendation has become necessary.

The usage of Drytch Fine Filters helps to achive Quality air as per above recommendation; which results in reduced wear and tear, incressed machine life/up time, lower rejections, better product quality and above all considerable saving in energy.
 
Housing are manufactured & tested to operate at 16 bar (max) working pressure at max 60°C temp. Filter with higher temp. also can be supplied if required. End Conn. Supplied upto model 007 is BSP female. End conn. Supplied model 009 V onward are of flanges ASA-150# or as per purchasers choice. All models are supplied with manual drain. Auto drain is optional at extra cost.

WARRANTY : Filter elements are warranted for one year. Filter housing are warranted for 5 years against defect in design, manafucturing and material

Subject to maintenance of the air contamination within level at inlet of filter combination.
Maximum flow handled by individual mode will be equal to the nominal flow of next higher model.
