Oil and Water-Repellent Membrane
Oil and Water-Repellent Membrane

Ganter offers elements equipped with membranes alongside aeration and ventilation elements with integrated filters and sieves. This makes it possible to prevent even smaller particles and oil and water droplets from passing through the ventilation openings. Dirt and moisture are kept away from the inside of the housing, and lubricants such as oils cannot escape. While the previous filter and sieve elements have a minimum mesh size of 100 µm, the standard membrane pores are only 1.2 µm in size.

PRODUCT’S STRENGHTS: PROTECTION AGAINST STRESS AND AIR FLOW MAX 34 L/MIN

Externally, the robust membrane is additionally protected against mechanical stress by a protective sieve made of stainless steel. Ideally, the standard part GN 7404 should be installed in vertical surfaces so that no liquids can collect on the membrane, which could impair the pressure balance. At a nominal differential pressure P1 to P2 of 1 bar, the maximum air flow – depending on the diameter – is up to 34 l/min. The membrane even retains its function up to an external pressure differential of 2 bar or an internal pressure differential of up to 10 bar. The maximum operating temperature is 100 °C.

MADE WITH NYLON FLEECE AND ACRYLIC COPOLYMER

The membranes themselves are made of a nylon fleece impregnated with an acrylic copolymer, and although the fibers are wetted, the porosity remains unchanged and can range between 0.2 and 10 µm if desired. Using a special process, the membrane is robustly bonded to a plastic ring socket by injection molding so that it can be firmly inserted into the stainless steel or aluminum screw fittings, sealed by an O-ring.
