YTF Panelless HEPA Filter Manufacturer

Panelless filters primarily use hot melt adhesive as the separator in the filter element, facilitating mechanized production. Furthermore, they offer advantages such as small size, light weight, easy installation, stable efficiency, and uniform airflow. Currently, the large-scale production of filters required in cleanrooms largely utilizes the panelless structure.

 HEPA filters with separators often use aluminum foil or paper folded into a shape as the separator to form air channels. The separators are made of high-quality kraft paper, hot-rolled or made of offset paper. Currently, double-sided coated paper is commonly used for the separators, primarily to prevent shrinkage due to temperature and humidity changes, which could lead to the release of particulate matter. When temperature and humidity change, these separator papers may release larger particles, causing cleanroom cleanliness tests to fail. Therefore, for locations with high cleanliness requirements, customers should be advised to use separatorless HEPA filters. 

Separated filters are more expensive than separatorless filters abroad, so they are less commonly used overseas. Furthermore, compared to the rectangular channels of separated filters, the V-shaped channels of separatorless filters further improve dust uniformity and extend service life. Separate filters for ventilation avoid the use of metal components, are easy to dispose of, and meet increasingly stringent environmental requirements. Except for certain special applications requiring high temperature resistance and high safety, separatorless filters can replace separated filters.
