Language
HVAC air filter media is a coarse-stage material fitted at the intake of ventilation and air-conditioning equipment, ahead of the finer filters in the system. It removes the bulk of large particles, dust and dirt before they reach coils, fans and ductwork in general ventilation and industrial pre-filtration. It is supplied as cut slices, framed slices or full rolls, so it can be used as a replaceable pad in a holding frame or fed into equipment that forms its own filter.
The media is a polyester fibre web combed into dense layers and bonded by hot air fusion, with the air outlet face covered by mesh and reinforced with cloth so the sheet keeps its shape and passes air evenly. A viscosity treatment holds captured dust in the media rather than letting it shake loose downstream. Dust holding capacity and the pressure drop the media adds decide how often the pad is changed and how much fan energy the system spends; a washable construction extends service life where the dust is not oily or sticky. Flame-retardant grades are available where the ductwork requires them.

Material characteristics
1. Made of elastic and break-resistant polyester fiber (PET), which is combed and laid in a dense layer by layer through hot air fusion process.
2. Each fiber is specially treated with viscosity to improve the long-term adhesion of captured particles to meet the strict quality requirements of coating technology.
3. The air outlet surface is covered with mesh and reinforced with cloth to ensure strength and air flow uniformity.
4. It has a certain corrosion resistance to general solvents, weak acids and weak bases.
