Self-cleaning air filter cartridge
BRADEN
Long-Life Cartridges
At the core of Braden's pulse-cleaning system is the ExCel™ cartridge - a highly efficient filter designed to be pneumatically cleaned. The medias either cellulose, a synthetic blend, or 100% synthetic, corrugated and pleated to form a conical or cylindrical media pack. The media pack is supported by a zinc-plated expanded metal liner on the inner and outer face of the filter. Hot melt adhesive bonds the media pack to both liners. The liners and media pack are then sealed into the end caps. The top cap has a pre-mounted, solid-rubber ring gasket to provide the clean air seal between the cap and the system's header plate. Braden also offers this filter with all metal parts using 304 or 316 stainless steel for corrosive environments.
Fast, Powerful Cleaning
Upon initiation of pulse cleaning, a solid state timer is activated which, in turn, fires the solenoid/pneumatic valves. The pneumatic valves send a sharp burst (or "pulse") of compressed air through the blow pipes and into the cartridges. This sharp burst of compressed air produces a shock wave and a momentary reversal of normal airflow. The collected particulate matter is dislodged, cleaning the cartridge media.
High Filtration Performance
AC Fine/NaCI tests have proven that ExCel™ filters have efficiencies fo 99.95% or higher. With particles of 10 microns and up, efficiencies of essentially 100% are recorded, with correspondingly high efficiencies in the range of .4-100 microns. The ExCel™ filter has successfully passed the ARAMCO test.
