Product detail · 详情说明
Bag media is chosen by gas temperature and chemistry: polyester covers ordinary dust, PPS and aramid suit hotter flue gas, and PTFE membrane is used for fine or sticky dust. Bag diameter and length must match the tube sheet, and the cage must fit inside the bag with the correct wire count.
Give the collector model, tube-sheet hole diameter, bag length, gas temperature and dust type. We match media, top fixing and cage construction as a set, and can quote replacement cages separately.
选型与验收要点 / Selection & acceptance points
- Media selected for gas temperature and dust chemistry
- Bag diameter / length matched to the tube-sheet hole
- Cage wire count and venturi matched to the collector
- Anti-static and PTFE membrane options available
