Tetratex® Release is a surface filtration PTFE membrane, laminated onto a variety of substrates for pulse jet baghouse applications, providing the flexibility to meet your needs. It acts as a primary dust cake requiring no precoat before or during operation. Tetratex® Release is thermally bonded onto the following needlefelts – Polyester/Epitropic anti-static, Polyester, Acrylic, P-84®, polypropylrne, P.P.S, Aramid, on felts and wovens. By limiting fine particle penetration, Tetratex® Release delivers high capture rates, whilst preserving the filter substrate’s integrity and maintaining optimum airflow at a reduced pressure drop. Resulting in higher air-to-cloth ratio, extended bag life and energy savings. A Low Cost PTFE Membrane with Unrivalled Dust Cake Release Properties Tetratex® Release membrane is highly permeable and suitable for use where dust particles are primarily larger than 3 microns.

Tetratex® Release membrane offers enhanced needlefelt surface finish, providing higher efficiency and superior dust cake release than other coated medias. Tetratex® Release is manufactured from PTFE Fluropolymer resin. It is a chemically inert material that virtually eliminates concerns regarding fibre contamination. Tetratex® Release membrane is thermally stable up to 287°C maintaining performance at high temperatures.
