Hydraulic Filter Elements
Elements
are the porous devices that perform the actual process of filtration.
Purolator offers a broad range of media to handle virtually any requirement.
Read the details on our three major media types below. Additional
information on topics related to filter elements may also be downloaded
in Adobe Acrobat PDF format. Follow these links:
| Microfil®
III media are made from micro-fine glass fibers which are
randomly laid into a multilayered web. The media are impregnated
with proprietary resins and thermally cured for strength and
stability. They are engineered with a tapered pore geometry
to provide superior contaminant capacity. Larger pores are located
on the upstream surface, with finer and finer pores in the depth
of the media. This proven media design philosophy gives Microfil
III superior on-stream life versus competitive elements. All
Microfil III elements are designed and tested to provide Beta
> 200 filtration efficiency. Microfil III elements
are offered in standard grades of 3, 6, 12 and 20 microns. They
are designed and tested to withstand 150 and 300 psid collapse
pressure, while Hi-Collapse Microfil® III is designed to
withstand 3,000 psid. |

Micropleat®
media are made from
resin-impregnated
cellulose materials. The media are then pleated and assembled
into economical Micropleat disposable elements. Micropleat elements
are rated at Beta = 2 and are available
in standard grades of 5, 10, 20, and 40 microns. They are designed
and tested to withstand 150 and 300 psid collapse pressure. |

Poromesh®
media are multiple layers of sintered wire cloth which
are pleated to maximize filter area and on-stream life. Our
proprietary sintering process metallurgically bonds each woven
wire to adjacent wires to maintain the desired micron rating
of the media even under severe pressures. Poromesh media are
made from 316L stainless steel wire meshes for excellent corrosion
resistance and high temperature tolerance. The elements are
electron beam welded—a
Purolator exclusive. This process eliminates heat distortion,
oxidation, and sensitization, providing superior product quality
at reduced costs. Poromesh elements are rated at 2, 5, 10,
20, and 40 microns nominal and are designed to withstand 150,
300 and 4500 psid collapse pressures. For 4500 psid elements
please contact Purolator.
