High Dust-Loading Bag Filter Media
HiLoad media by Handanhy are ideal materials for making bag filters due to their high load capacity for storing dust. Designed specifically for this purpose, using the latest research and stringent testing, HiLoad media is proven to be less harmful to the environment in comparison with similar, competing products.
Product Introduction
Compared with previous synthetic media, HiLoad significantly enhances the dust-loading capacity which leads to a prolonged life-expectancy of air filters. There has been a big debate on the discharge of synthetic media, but no matter how the argument goes, Handanhy’s HiLoad showed a higher efficiency in the isopropanol(IPA) tests. For example, HL-F7 will achieve 25% efficiency after IPA treatment as per EN779 or ISO/DIS21220. This is well above the expected criterion of 20%.
The major component of HiLoad is polypropylene, or PP. During combustion for disposable filters, PP produces only CO2 and water, which has little impact on the environment compared with other plastics and related dust loading bag material products available in the market. The electrets made of PP, which enhance the capture performance of airs filters, are stable.

A Comparison of Dust-loading for filters of HiLoad to fiberglass and other synthetic media
- Dark Green: HiLoad
- White: Fiberglass
- Light Green: HY Previous
- Yellow: Competitor A
- Pink: Competitor B
Sample filters were tested per CRAA standard which is equivalent to EN779. For comparison purposes, the dust-loading for fiberglass is set to 100%.
For customers’ convenience, Hengyong can supply sonic sewed filter bags, endless roll or individual bags.
Real filters are in various configurations and the net filtration media are all different. The efficiency of an end filter may vary from media tests. Our efficiency grade can be applied to most bag filters in general designs, but may not be correct for some specially designed filters, for example, filters with very short bag length or very few pockets. The efficiency grade of special designed filters should be tested and suggested by filter manufactures.
