MikroPul pulse-jet collector (224 bags) 12,000 cfm, 175°F; 4.4:1 air-to-cloth ratio; inlet loading: 72.8 to 97.0 gr/acf; particle size 10 percent submicron.
1. Severe bleed through; 2. Frequent after filter replacement and downtime. The fine, spherically shaped dust at high inlet loading migrated through every bag media tried previously. Secondary after-filters were blinded and changed out two to three times per week. Production loss downtime was excessive.
Installed a full set (224) of GORE® membrane/polyester felt filter bags.
Secondary after-filter blinding was eliminated. GORE® membrane filter bags were cost justified in less than one month. Bag life was expected to approach two years. Customer quickly converted all SAN and ABS dryer systems to GORE®membrane filter bags. Customer increased profits substantially in these areas.
