What is the difference between bag pleated filer cartridge and filter bag?

Bag pleated filter cartridges combine the high flow rate of high-flow filter cartridges with the ease of installation of filter bags. Current filter bags suffer from low retention efficiency and poor filtration performance, especially for battery-grade and electronic-grade products, which cannot meet the filtration standards of conventional filter bags. Bag-type pleated filter cartridges, however, can achieve a filtration precision as low as 0.1μm.

Why LOONG Filtration design this kind of bag pleated filter cartridge?

Current filter bags have low retention efficiency and poor filtration effect, making it difficult to meet customers' filtration needs. However, customers want to improve filtration efficiency without replacing bag filters. Therefore, LOONG Filtration has developed this filter cartridge for this type of customer.

Are the interfaces of bag pleated filter cartridges and filter bags the same?

Yes, and the installtion way is totally same with filer bag.

What type of filter is used in bag pleated filter cartridges?

Same with filter bag, so customer no need to replace the new filter.

Is one-stop shopping at LOONG filtration possible?

LOONG Filtration is dedicated to provide one-stop shopping experience, to simplify customers' purchasing process. We have a wide variety of products covering a wide range offields, so we believe you can find what you need.
