Breathers and Strainers

Purolator offers a full line of hydraulic reservoir breathers and filler breathers. The products filter the air which breathes into and out of the reservoir, helping to maintain hydraulic fluid purity. Purolator suction strainers are used as coarse filtration on the suction inlet of the hydraulic pump. They are made of die-cast aluminum endcaps, pleated steel cores, and stainless steel filtration mesh. Options include mesh size, length, threads, diameter, and bypass valves.

Microfil III media

Microfil III media are made from micro-fine glass fibers which are randomly laid into a multi layered 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 Bx > 200 filtration efficiency. Microfil III elements are offered in standard grades of 1, 3, 6, 12, 20, and 25 microns. They are designed and tested to withstand 150 and 300 psid collapse pressure, while Hi-Collapse Microfill III is designed to withstand 3,000 psid.

Micropleat Media

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 Bx = 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

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 eliminated 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 JB Systems.
