E9 stage filter for filtering a liquid and a 3 micron size condensing special (5ppm w/w maximum residual oil content ) double stage filtering the first two stainless steel pipe, 10 micron mechanical separation of second level deep fibrous medium filtering 3 micron liquid and solid particles
E7 stage filter applied in addition to liquid water and oil can be as small as 1 microns; filtering the solid particles ( 1.0ppn w/w maximum residual oil content ), all within the framework of corrosion of two-stage filtration first fiber medium and medium filter alternately laminated, remove larger particles second multilayer environment resin adhesive mixing fiber medium, coalescence of oil mist and filtering the solid particles
E5 stage filter state applies to the coalescence of small water vapor and oil mist; less than 0.01 micron filter and the solid particles ( 0.01ppm w/w maximum residual oil content ) and skeleton are corrosion resistant dual stage filtration first multilayer fiber medium and medium filter, filter out the larger particles in the air, into the second stage filter before pre filtering level second multilayer adhesive blend fibers filter medium, small aggregates external coating closed foam sleeve
E3 stage filter applied to the coalescence of small water vapor and oil mist; can filter solid particles as small as 0.01 microns ( 0.01ppm w/w maximum residual oil content ), all within the framework of corrosion of two-stage filtration first film closed foam sleeve, pre filtering and disperse second level multi layer hybrid fiber matrix dielectric, filter extremely fine aggregate foreign film closed foam sleeve
E1 stage filter for filtering active carbon usually can absorb oil vapor and hydrocarbon vapor; can filter solid particles as small as 0.01 microns ( 0.03ppm w/w maximum residual oil content ), all within the framework of corrosion of two-stage filtration first level very fine powder activated carbon stable layer, filter out most of the second oil vapor stage multi-layer fiber medium, bonded micro fine powder activated carbon, can remove residual oil vapor multilayer fine medium, prevent from the pollutant movement with closed cell foam sleeve, to prevent the fibers around the rated operating conditions, the design life of 1000 hours
