 Air Filter - Model specifications and performance parameters 

 Separation filter (HF9) 
 For 3-micron filter out a lot of liquids and the size of the condensate (5ppm w / w maximum remaining oil content) 
 ◆ Two-stage filter 
 ◇ Level 1 - two stainless steel bore tube, a 10 micron mechanical separation 
 ◇ Level 2 - 3 microns deep fiber filter media, solid and liquid particles 
 Charge passing through the filter (HF7) 
 For a large number of liquid and 1 micron filter size of condensate (1.0ppm w / w maximum residue oil content) 
 ◆ internal / external filters are corrosion resistant 
 ◆ Two-stage filter 
 ◇ Level 1 - fiber media and media alternately laminated filter, filter the larger particles 
 ◇ Level 2 - multi-fiber epoxy adhesive mixed media, oil mist and the coalescence filter out solid particles 
 Efficient oil removal filter (HF5) 
 For coalescence of small water vapor and oil mist; can be as small as 0.01 micron filter condensate (0.01ppm w / w maximum remaining oil content) 
 ◆ internal / external filters are corrosion resistant 
 ◆ Two-stage filter 
 ◇ Level 1 - multi-fiber media and media filters, filter out larger particles in the air filter before entering level 2 pre-filter 
 ◇ Level 2 - multi-fiber bonding mixed media, filter out small condensate 
 ◆ closed foam sleeve outer coating 
 Ultra-high efficiency oil removal filter (HF3) 
 For coalescence of small water vapor and oil mist; can be as small as 0.01 micron filter condensate (0.01ppm w / w maximum remaining oil content) 
 ◆ internal / external filters are corrosion resistant 
 ◆ Two-stage filter 
 ◇ Level 1 - coating foam sleeve closed, pre-filter and air dispersion 
 ◇ Level 2 - Multi Matrix mixed fiber media, filter out very small condensate 
 ◆ closed foam sleeve outer coating 
 Steam degreasing filter (HF1) 
 Activated carbon filter is usually applied to absorb the oil vapor and hydrocarbon vapors; can be as small as 0.01 micron filter out solid particles (0.003ppm w / w maximum remaining oil content) 
 ◆ internal / external filters are corrosion resistant 
 ◆ Two-stage filter 
 ◇ Level 1 - a very fine stable layer of activated carbon powder, can filter out most of the oil vapor 
 ◇ Level 2 - multi-fiber media, activated carbon powder bonded micro fine filter can filter out the remaining oil vapor 
 ◆ multi-media fine, to prevent pollutants from wavering 
 ◆ closed foam sleeve outer coating to prevent fiber wavering 
 ◆ at rated operating conditions, design life up to 1000 hours
