Case Study:
Multifit Pleated Bag with Weltech straps & PTFE coated filter media resulted in more than 3 times longer filter life cycle
Location:
- CHINA
Operation:
Chemical - Glass
Dust type:
Gas & dust from glass production
Problem:
- The customer wanted to prolong the life cycle of their filters (Previous pleated bag filters lasted max. 8 months)
- Wanted to avoid problems with the straps falling off and pleat joint that loosened when operating at temperatures above 85°C
Solution:
- Filter life cycle: Nordic Air Filtration's Multifit Pleated Bag with PTFE coated filter media was chosen. This filter media is very durable and it provides optimal dust release.
- Straps falling off and pleat joints that loosened: Ultrasonic welded Weldtech straps was used eliminating the need of using glue. The WeldtechTM technology is ideal for chemical dust as it has optimal heat tolerance and is gluefree.
- Today, the Multifit cartridges with EldtechTM straps are being off-line cleaned every 6 months using a vibrating steel bar inside the cartridges while mounted in the collector.
Under the above conditions, the Multifit solution lasts more than 3 times longer than the previous filter products.
