Product name: HZL Series Medium Efficiency Air Filter, sub high efficiency air filter

●Outer frame: galvanized steel plate, plastic.

●Filter Material: Ultra fine polypropylene filter paper, glass fiber filter paper.

●Filtration efficiency: high efficiency, sub efficiency, medium efficiency.

●High air volume type: Compared with ordinary high-efficiency filters, fewer filters can be used at the same air volume, reducing costs, installation space, and saving installation time.

●High dust content, no partition design: The filter is made of ultra-fine, moisture-proof, fire-resistant glass fiber, and thermoplastic rubber barrier ensures the same fold spacing, ensuring that the air flow passes with small resistance. With the same fold spacing, the entire depth of the filter material is fully utilized, ensuring a greater dust capacity.
