The courtyard cotton sheet filter is an air filtration equipment mainly made of courtyard cotton as the filtering material. The following is its detailed introduction:

Tianjing cotton sheet filterStructural characteristics：

1. Filter material: The ceiling cotton is a high-performance non-woven fabric made of anti fracture synthetic fibers, which has good flexibility and strength, is not easily damaged, and can withstand certain airflow impacts.

Incremental structure: Adopting gradually increasing multi-layer technology, that is, the fiber density gradually increases towards the direction of pure air. This structure allows dust particles to be blocked at different density levels based on their size, effectively accommodating more dust and extending the lifespan of the filter while maintaining high filtration efficiency.

2. Adhesive treatment: The adhesive completely penetrates the medium, preventing dust particles from passing through and further improving the filtration effect.

3. Outer frame material: Generally matched with paper frame, galvanized frame or aluminum frame, these outer frame materials have the characteristics of light weight, strength, corrosion resistance, etc., which can provide good support and protection for the filter material, ensuring the stability and reliability of the filter during use.

Performance parameters of courtyard cotton filter:

1. Filtering level: The filtering level of the cotton leaf filter in the courtyard is generally F5, which has a good filtering effect on particles larger than 1 micron, with an average weight efficiency of about 98%. It can effectively remove dust, pollen, hair and other impurities in the air, providing pre filtration guarantee for subsequent air purification equipment.

2. Resistance characteristics: The initial resistance is usually around 30Pa. When operating at rated air volume, the resistance gradually increases with the increase of usage time and dust accumulation, and the final resistance is generally set at 450Pa. A lower initial resistance can reduce the energy consumption of the system, and a reasonable final resistance setting can help remind users to replace the filter in a timely manner to ensure the filtration effect and normal operation of the system.

3. Dust holding capacity: At the final resistance, the dust holding capacity can reach 400g/㎡. A larger dust holding capacity means that the filter can hold more dust, reducing replacement frequency and lowering usage costs.

4. Temperature resistance performance: The continuous temperature resistance of the courtyard cotton can reach 100 ℃, and the instantaneous temperature resistance can reach 120 ℃, which can meet the temperature requirements of general industrial environments and air conditioning systems, ensuring stable operation under different working conditions.

Application fields of courtyard cotton filter:

Industrial coatingIn industrial painting workshops such as automobile manufacturing, furniture manufacturing, and machinery manufacturing, courtyard cotton leaf filters can be used for end filtration in paint spraying rooms, effectively capturing paint mist particles, preventing paint mist from entering the ventilation system and atmospheric environment, protecting workers' health, and avoiding paint mist pollution to equipment and the environment.

Electronic ManufacturingThe electronic production workshop has high requirements for air cleanliness. The cotton leaf filter in the courtyard can be used as a pre filter in conjunction with high-efficiency filters to remove dust and impurities from the air, prevent damage to electronic components, and improve product yield.

Pharmaceutical industryIn the air conditioning system of pharmaceutical factories, the courtyard cotton filter can filter out pollutants such as microorganisms and dust in the air, providing a relatively clean air environment for drug production, ensuring drug quality and production safety.

food processingInstalling a ceiling cotton filter in the ventilation system of a food processing plant can prevent dust, hair, and other foreign objects from entering the production workshop, avoid contaminating food, and ensure food hygiene and quality.

Air conditioning and ventilationIn the central air conditioning systems of various buildings, the courtyard cotton filter serves as the primary filter, which can effectively filter out large particulate pollutants in outdoor air, reduce the burden on subsequent filters, extend the service life of the entire air conditioning system, and improve indoor air quality.

Maintenance and replacement of courtyard cotton filter:

Daily maintenance: Regularly check the usage status of the filter. If there is a lot of dust accumulation on the surface, a vacuum cleaner can be used to clean and restore some of the filtering performance. For slightly polluted courtyard cotton, it can also be cleaned and reused, but attention should be paid to the cleaning method and frequency to avoid excessive cleaning and damage to the filter material.

Replacement cycle: When the resistance of the filter reaches the final resistance, or when the filtering effect significantly decreases and cannot meet the usage requirements, the ceiling cotton pads should be replaced in a timely manner. Generally, the replacement cycle is around 3-6 months depending on the usage environment and air quality.
