| End caps of polymer material | | - No "afflorescence" and therefore no formation and accumulation of bacteria
- No damage to the screw thread in the filter head
- Filter remains undamaged even without greasing
| | |
| Larger filter area with up to 8-fold winding | | - Depth filtration instead of surface filtration increases the available filter areaAdvantages::
- Differential Pressure increases less rapidly
- Greater efficiency of the element due to improved absorption
| | |
| Drainage layer of needle felt | | - Does not swell as air or gas streams through, therefore no cracking
- Needle felt does not contain any silicon
- Can withstand temperatures up to 120 C
| | |
| Spirax stainless steel cylinders | - Internal and external supporting cylinders of stainless steel
- Up to 40% lower pressure difference due to the special form and arrangement of the open surfaces
- More stable than conventional perforated plates and expanded metal, therefore more reliable operation and longer duty periods
- Alternative filter elements are available for:Alup - Atlas Copco - Beko - Boge - Compair - Deltech - Domnick Hunter - Ecoair - Hankison - Hiross - Ingersoll Rand - Kaeser - Sullair - ultrafilter - Zander
