Introduction:
HEPA filter is a common air filtration equipment in clean rooms, dust-free workshops and other environments. According to the different internal structure, it can be divided into two types: mini pleat and deep pleat. This paper mainly introduces the deep pleat HEPA filter.
The inside of the Deep Pleated HEPA Filter uses aluminum foil or paper separator to fold the filter material into a corrugated shape to create a uniform air passage, and the outside uses a metal frame to assemble all the parts together.

The design of the separator can effectively increase the filtration area and improve the filtration efficiency.
Deep Pleated HEPA Filter removes 99.97% of particles 0.3μm or larger from the air. This highly efficient filtration capability makes it widely used in environments that require a high degree of cleanliness.
Because the deep pleat HEPA filter is supported by the separator, the air flow is smooth, so the initial pressure loss is low. This means that the deep pleated HEPA filter uses less energy for the same air volume.
Separators increase the structural strength of the filter, reduce the risk of deformation or rupture under high pressure differential conditions, and extend the service life.
The Deep Pleated HEPA Filter provides high efficiency filtration, stable structural performance and low maintenance costs in applications where high efficiency air filtration is required.

Performance characteristics:
1. Efficient filtration: The separator design helps the air pass through the filter material more evenly, which can improve the filtration efficiency and effectively remove small particles and harmful substances in the air.
2. Structural stability: The Deep Pleated HEPA Filter adopts aluminum foil or paper separator to support the filter material, which can enhance the structural stability of the filter, so that it is not easy to deform or break under high wind speed or high pressure difference, and has a long service life.
3. Reduce energy consumption: The separator design helps to reduce the air resistance, reduce the energy consumption of the equipment during operation, and improve the operation efficiency of the equipment.
Application place:
The Deep Pleated HEPA Filter is suitable for places with large air volume and high pressure, mainly including electronic manufacturing, pharmaceutical, food processing and other industries.
Electronic manufacturing: In the process of electronic manufacturing, it is necessary to efficiently filter the fine dust and electrostatic particles in the air to ensure the cleanliness of the production process and the quality of the product. The Deep Pleated HEPA Filter can provide efficient air filtration, suitable for electronics manufacturing workshops, clean rooms,dust-free workshops and other environments with high cleanliness requirements.
Pharmaceutical industry: In the pharmaceutical production process, the air quality requirements are extremely high, and it is necessary to effectively filter the particles in the air to ensure the quality and safety of drugs. The Deep Pleated HEPA Filter can efficiently filter particles for pharmaceutical factories, laboratories, clean areas and other places.
Food processing industry: It is necessary to keep the air clean and hygienic during food processing to prevent particles, dust and other contamination of food. The Deep Pleated HEPA Filter can effectively filter the particles in the air, clean the air, and make the finished products meet the food safety and hygiene standards. It is suitable for food processing workshops, packaging areas, clean rooms and other environments.
