Composite Bag Filter Media

Product Introduction

Composite bag filter media is made up of various types of polypropylene. It is an economical media, as polypropylene is one of the most cost-effective synthetics. The types of polypropylene used are all flat and dull, meaning there is no risk to the environment, and the material can be discarded without concern. Not only does the material have a three-dimensional net structure, but it also forms rough, fine filter layers. The filter media for bag filters has high air filtration efficiency, and adapts to the demands of multilayers of filter material and gradient filtration, which helps to prolong the lifespan of the products. The product can be widely used for bag filters and panel filters in general ventilation systems.

Product Performance

  • The media is manufactured using eco-friendly, harmless polypropylene, which can be discarded without causing damage to the environment.
  • The filter media density is increased, and more dust can be contained which prolongs the lifespan of the product.
  • Little initial resistance and high efficiency.
  • The media uses the same appearance color universally and can be identified easily.
  • The media can be made into a molding filtration bag and can be disparted.

Filter media HY-B-F7 by Hengyong, suitable to make F7 grade bag filters.
Example: HY-A-F6D

Bag filter media HY-A-F6D by Handanhy, suitable for making F6 grade bag filters, ultrasonic sewing bags or endless rolls. For customers’ convenience, Handanhy can supply sonic sewed filter bags, endless rolls or individual bags. Handanhy promises not to manufacture any assembled filters which compete with our customers.

HiLoad media by Hengyong are ideal materials for making bag filters. Compared with previous synthetic media, HiLoad significantly enhances the dust-loading capacity which implies a prolonged life-expectancy of air filters. There has been a big debate on the discharge of synthetic media. No mater the argument goes, Hengyong’s HiLoad showed a higher efficiency in the isopropanol(IPA) tests. For example, HL-F7 will get a 25% efficiency after IPA treatment per EN779 or ISO/DIS21220. This is well above the fighting criterion 20%. The major components of HiLoad is polypropylene, or PP. During combustion for disposable filters, PP produces only CO2 and water. Thus little impact is on the environment compared with other plastics. The electrets made of PP, which enhances the capture performance of airs filters, are stable.
