Panel Pre Air Filter

A panel pre-air filter is a type of air filter that is designed for use in cleanrooms and other controlled environments. These filters are typically installed in the ceiling or walls of a cleanroom and they are used to remove large particles and contaminants from the air before it is passed through the main cleanroom filter. Panel pre-air filters are commonly made from materials such as polyester or polypropylene, which are effective at trapping large particles from the air. It removes pollutants from airflow and improves indoor air quality. Avoid accumulation of contaminants in equipment that could damage it. Such air filter design products usually do not exceed 18 cm in depth. They are used as primary filters in clean rooms, providing low to medium levels of air filtration. They are typically used in low to medium-efficiency cleanrooms, and they are typically replaced on a regular basis to ensure that they continue to effectively remove contaminants from the air.
Cleanroom panel pre-air filters are typically made by enclosing a filter media, such as fiberglass or synthetic fibers, within a perforated metal or plastic frame. The frame is then sealed with a plastic or rubber gasket to prevent air leakage. The filter is mounted on a panel, which can be easily installed in the cleanroom. This allows the filter to be easily accessed for cleaning and maintenance, while also maintaining the integrity of the cleanroom environment.
Cleanroom panel pre-air filters are commonly used in cleanrooms and other controlled environments where it is important to maintain the cleanliness of the air. They are typically used in industries that require strict cleanliness standards, such as pharmaceuticals, medical devices, and semiconductors. When choosing a cleanroom panel pre-air filter, it is important to consider the specific requirements of your cleanroom, such as the size and shape of the cleanroom, the level of cleanliness required, and the types of hazardous materials that will be used. By carefully evaluating these factors, you can determine the right cleanroom panel pre-air filter for your needs.

Panel air filters are also used as middle and rear air filtration equipment in places where cleanliness requirements are not high.
Panel air filters are often used as pre-filters in clean rooms and are installed at the front of the entire air filtration system to avoid the impact of larger particle contaminants in the more expensive filters in the middle and rear. Extend the life of the air filter in the middle and rear sections.
Panel air filters are primary filters in healthcare facilities, pharmaceutical plants, industrial applications and institutional applications.
Panel air filters are compact, small, lightweight, easy to clean, assemble and disassemble, and can be installed individually or in front of a laminated bag filter. The plate filter is mainly used to filter and remove dust particles ≥5μm in the air conditioning system, protect the air filter in the middle and rear sections, and prolong its service life.
