Product characteristics of RTO filter cotton:

1. Air filter cotton is processed by high-performance hot melt method using anti breakage organic synthetic fibers;

2. Incremental structure, utilizing gradually increasing multi-layer technology, where the fiber density gradually increases towards the direction of pure air, resulting in higher filtration efficiency. It can be blocked at different density levels according to the size of dust, effectively accommodating more dust;

3. The air outlet surface of the filter is particularly dense, and a layer of grid woven mesh is added to strengthen the shaping. This structure enables the filter material to maintain a high filtration effect and dust holding capacity, and can also extend its service life;

4. Compliant with fire classification standards European DIN53438-F1 and American UL900-CLASS 2;

5. Paired with paper and metal frames, it is often used to make plate filters.

6. Mainly filters dust particles larger than 5 μ m;

7. Made by processing high-performance and high-strength synthetic fibers in an incremental structure;

8. It has the characteristics of high dust holding capacity and low resistance, and strong flame retardancy;

9. Long usage time, can be used multiple times after cleaning, economical and practical;

10. Paired with paper frames and metal frames, it is commonly used to make filter media for plate type primary filters, washable plate filters, paper frame filters, bag type primary filters, and other filters

Technical parameters:

The main applications of RTO filter cotton are:

1. RTO filter cotton is generally used at the suction inlet of ventilation equipment and air control systems as a pre filter or coarse filter that comes into direct contact with outdoor air;

2. Suitable for various industrial applications, such as spraying industry, pollution prevention and control, public construction, air conditioning industry, electronics industry, pharmaceutical factories, food industry, etc
