KAY-TEX® e-ptfe membrane


KAY-TEX® products are laminates using an expanded microporous PTFE-Membrane that is bonded to the surface of needlefelts, fabrics or spunbonds.
These lamiates offer highest filtration efficiency (>99,99%), superior cake release and increased airflow at lower energy consumption.

The dust do not penetrate into the support medium - needle felt or fabric - thus avoiding the clogging of the filter media.

The high anti-adhesive effect of the e-ptfe membrane means that the filter medium shall be cleaned less frequently and with less intensity, resulting in a longer filter media life with improved emission and pressure differential values.

Advantages compared with conventional filter bag media

The conventional approach in filtration: Using standard fabric filter media, filtration occurs as a result of the formation of a primary dust cake (the initial layer of dust) on the surface of the filter bags and an accumulation of dust particles within the structure of the filter media. Over time, the dust becomes permanently trapped in the depth of the fabric resulting in higher differential pressure and reduction in process ventilation. It also causes the filter bags to “blind” which reduces filter life.
