Adding an ePTFE membrane to an aramid filter bag allows the membrane to act as the filter cake. Dust stays on the surface of the membrane and does not get entrained into the fibers of the filter bag, which lengthens the life of your filter bag. It also reduces wear and tear, lower maintenance costs, and energy costs due to easy dust cake release during the cleaning cycle.
PPS filter bags are also known as polyphenylene sulfide fiber bags or ryton fiber bags, the physical properties of its fiber are obviously better than other high temperature resistant acid and alkali resistant filter bag products. Commonly used in industrial applications where high temperature and chemical resistance are required. They are designed to filter dust, particulate matter, and other contaminants from air or gases in various processes.
High Temperature Resistance – Continuous 190°C, peak 200°C
Excellent Chemical Resistance – Stable under acid, alkali, and oxidizing gases
Long Service Life – Durable PPS fiber with PTFE membrane finishing
Stable Emissions – Achieve ultra-low emissions under harsh conditions
