Product Features

HEPA Filter: HEPA filters are highly efficient at capturing particles as small as 0.3 microns with a high level of effectiveness, typically removing at least 99.97% of airborne particles.

Knife-edge Frame: The knife-edge frame refers to the frame design of the filter, which typically has sharp edges for a tight seal when installed in air handling systems. This helps to prevent air bypass and ensure that all air passing through the filter is effectively cleaned.

Mini-Pleat Design: Mini-pleat refers to the arrangement of the filter media, where the filter material is folded into small pleats to increase the surface area available for filtration. This design maximizes filter efficiency and reduces pressure drop across the filter, allowing for better airflow while maintaining high filtration performance.

Panel Filter: Panel filters are flat filters commonly used in HVAC (heating, ventilation, and air conditioning) systems. They are designed to be installed in filter housings or air handling units to capture airborne particles as air passes through the system.

Overall, a HEPA knife-edge frame mini-pleat panel filter combines the high efficiency of HEPA filtration with the compact design of mini-pleat technology and the easy installation of panel filters, making it ideal for applications requiring superior air quality control.

In pharmaceutical factories, biological facilities, and food processing plants, maintaining strict air quality control is crucial to ensure product safety and compliance with regulatory standards. Here's how HEPA knife-edge frame mini-pleat panel filters could be applied in these settings:

Pharmaceutical Factory: Pharmaceutical manufacturing facilities require highly controlled environments to prevent contamination and ensure product quality. HEPA filters are essential for removing airborne particles, bacteria, and other contaminants that could compromise the integrity of pharmaceutical products. The knife-edge frame design ensures a secure fit and minimizes air bypass, while the mini-pleat configuration maximizes filtration efficiency without impeding airflow. These filters can be used in cleanrooms, sterile compounding areas, and other critical production areas to maintain ISO cleanliness standards.

Biological Factory: Biological facilities, such as those involved in biotechnology or genetic research, often handle sensitive materials that must be protected from airborne contaminants. HEPA filters are essential for maintaining sterile conditions and preventing cross-contamination between different biological samples or cultures. The mini-pleat design provides a large surface area for filtration within a compact space, making it ideal for use in biological safety cabinets, laminar flow hoods, and other containment systems.

Food Processing Factory: In food processing plants, maintaining a clean and sanitary environment is essential to prevent contamination and ensure food safety. HEPA filters can help remove airborne particles, allergens, and microorganisms that could contaminate food products during processing. The knife-edge frame ensures a tight seal, preventing air leaks and maintaining the integrity of the filtration system. These filters can be used in processing areas, packaging rooms, and other critical control points to meet regulatory requirements and ensure product quality.

In all these applications, HEPA knife-edge frame mini-pleat panel filters play a critical role in maintaining strict air quality control, protecting product integrity, and ensuring compliance with industry regulations.
