W-shaped box-type high-efficiency filter

W-shaped box-type high-efficiency filter

I.Structural Features

Non-partition Design: Adopts a non-partition structure, using thermoplastic spacer glue to ensure uniform pleat spacing. It fully utilizes the filter media depth and increases dust-holding capacity.

W-type Structure: The filter media is folded into a “W” shape, providing a large effective filtering area. It requires fewer filters under the same air volume, saving installation space and time.

II.Material & Performance

Filter Media: Usually made of ultra-fine polypropylene filter paper or glass fiber filter paper. It has high-efficiency filtration performance, capable of capturing 0.3μm dust particles with a filtration efficiency of H13-H14.

Frame Material: Common frame materials include galvanized steel sheet, ABS engineering plastic or aluminum alloy. They are lightweight with low initial resistance. Among them, ABS plastic frames can be incinerated after disposal, which is environmentally friendly and saves garbage disposal costs.

Sealing: Generally uses polyurethane sealing to ensure the airtightness of the filter and prevent unfiltered air leakage.

III.Application Fields

Commercial Buildings: Widely used in heating, ventilation and air conditioning (HVAC) systems of large civil buildings such as office buildings, meeting rooms, hospitals, shopping malls, stadiums and airports.

Industrial Fields: Suitable for centralized HVAC systems of general industrial workshops or clean rooms. It is applied in industries with high requirements for air cleanliness, such as electronics, semiconductors, pharmaceuticals, food and precision machinery.
