Product Features

The outer frame of the filter is composed of a solid waterproof board, used to fix the folded filter material. The design of diagonal line on the outer frame can provide large filtration area and make the internal filtration material tightly adhere to the outer frame. . .

Product Description: First-effect folding air filter is suitable for primary filtration of air-conditioning system, mainly used to filter dust particles above 5 μ m. The primary filter has three styles of plate type, folding type and bag type. The outer frame material includes paper frame, aluminum profile frame and galvanized plate frame. The filter material includes non-woven fabric, nylon net, activated carbon filter material, metal hole net, aluminum rolled net, etc.

Product features: cheap, light weight, good versatility, compact structure.

Product selling point: replaceable filter material. Users can conveniently replace the filter media by themselves, which can save the cost of spare parts for users and reduce the troubles of transportation and storage.

Main application: the primary filtration of a common air-conditioning and ventilation system is also suitable for simple air-conditioning and ventilation system with only one-stage filtration.

Frame material: paper frame, aluminum profile frame, galvanized sheet frame.

Sealant: polyurethane adhesive.

Use filter material: non-woven fabric, nylon mesh, activated carbon filter material, metal mesh, aluminum rolling mesh.

Divider: hot melt adhesive

Features: The outer frame of the filter is made of solid waterproof board, which is used to fix the folded filter material. The design of diagonal line on the outer frame can provide large filtration area and make the internal filtration material tightly adhere to the outer frame. Special professional bonding glue is used around the filter to bond with the outer frame, which can prevent air leakage or damage caused by wind resistance pressure. 　　

Efficiency: G3, G4

Service environment: normal temperature and pressure

Weatherstrip: neoprene

Application examples: pre-filtration of central air-conditioning and central ventilation system; Large air compressor pre-filtration; Pre-filtration of clean return air system and local high-efficiency filtering device.
