Hot Pressed Laminated cotton Hepa Filter Material For HVAC Systems Industrial

Hot Air Cotton with Hot-pressed Laminated Mesh for HVAC Systems Industrial 

1. Dedicated Substrate for Air Filters: Hot Air Cotton Composite Metal Mesh

This hot air cotton composite metal mesh is the core substrate of the air filter. It is made from high-quality hot air cotton and metal mesh using a high-temperature hot air coating process. The metal mesh layer is made of high-quality materials such as galvanized steel wire and stainless steel wire, ensuring a tight bond with the hot air cotton and preventing delamination. The product combines the high breathability of hot air cotton with the strong support of the metal mesh. It can be used directly as the middle layer substrate or pre-filtration reinforcement layer of the filter, suitable for the production of various air filters in household, commercial, and industrial applications, providing a stable structure and basic filtration guarantee for the filter.

2. Enhanced Metal Mesh Support for Improved Filter Durability

The metal mesh in the composite layer uses a precision weaving process, resulting in uniform mesh size and excellent toughness. This effectively enhances the structural strength of the hot air cotton, preventing deformation, damage, and collapse of the filter during cutting, installation, and use. Compared to pure hot-air cotton substrate, the addition of metal mesh increases the tensile strength of the filter by over 60%, making it suitable for high-velocity, high-frequency disassembly and reassembly scenarios. This extends the overall lifespan of the air filter and reduces subsequent operating costs for customers.

3. High-Temperature Burnishing Process Optimizes Filtration and Ventilation Performance

The product utilizes a high-temperature burnishing process, resulting in a smoother, more even surface for the hot-air cotton, reducing dust adhesion and residue. It also optimizes the breathability structure, achieving an airflow resistance as low as 8Pa/㎡, far exceeding the ventilation efficiency of ordinary composite substrates. While ensuring basic filtration (intercepting large particles, hair, and dander), it does not affect the overall airflow of the air filter, perfectly matching the duct design of air purifiers, fresh air systems, and other equipment, balancing filtration effectiveness with equipment operating efficiency.

4. Comprehensive Customization Service to Meet Diverse Filter Needs

We support customized parameters to precisely match the production needs of different air filters: metal mesh can be made of galvanized steel, stainless steel, etc., and mesh size (50-200 mesh) is adjustable; hot air cotton thickness (1-5mm) and weight (30-100g/㎡) are customizable; product sizes can be cut into rolls and sheets to fit various filter shapes such as round, square, and irregular shapes. We can also adjust the composite process according to customer requirements to meet the customized production needs of filters for special scenarios.

5. Environmentally Friendly Materials with No Secondary Pollution, Suitable for Multiple Filtration Scenarios

The hot air cotton is made of food-grade polyester fiber, and the metal mesh is made of environmentally friendly galvanized/stainless steel. No harmful additives are added throughout the process, and there is no odor emission. The production process meets environmental standards. The product is suitable for air filters in sensitive scenarios such as mother and baby rooms and bedrooms, and can also be used in the manufacture of filters for complex scenarios such as industrial dust removal and commercial ventilation. There is no dust shedding or secondary pollution during use, ensuring the cleanliness and safety of the filtered air.
