A mini pleat HEPA/ULPA air filter is a type of air filter that is designed for use in cleanrooms and other controlled environments. HEPA (High-Efficiency Particulate Air) filters and ULPA (Ultra-Low Particulate Air) filters are air filters that are able to remove 99.97% and 99.999% of particles that are 0.3 microns or larger in size, respectively. They are commonly used in cleanrooms and other controlled environments, where they are used to remove particles and contaminants from the air in order to maintain a high level of cleanliness.
It is a high-efficiency filter capable of removing very fine particles from the air, including particles as small as 0.3 microns (for HEPA filters) or 0.1 microns (for ULPA filters).
MiniPleat HEPA/ULPA air filters are often used for intake and recirculation air filtration in cleanrooms and laminar flow hoods with ultra-stringent requirements for clean air and sterility. The employed MiniPleat technology ensures a flow-friendly geometry and equidistant pleats with uniform media velocity and very low-pressure drop.
Mini pleat HEPA/ULPA air filters are made by folding the filter media into a series of small pleats, which increases the surface area of the filter and allows it to remove more particles from the air. The pleated filter media is then enclosed within a metal or plastic frame, which is sealed with a plastic or rubber gasket to prevent air leakage. This design allows the filter to remove particles and contaminants from the air while still allowing air to flow through the filter.
Mini pleat HEPA/ULPA air filters are commonly used in cleanrooms and other controlled environments where it is important to maintain a high level of cleanliness. They are typically used in industries that require strict cleanliness standards, such as pharmaceuticals, medical devices, and semiconductors. When choosing a mini pleat HEPA/ULPA 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 mini pleat HEPA/ULPA air filter for your needs.
Computer-controlled thermal bead pleat spacing during its manufacture eliminates aluminum corrugated gaskets and minimizes pack depth.
Youth Cleanroom HEPA/ULPA Mini Pleated Air Filters fully seal the filter media within an aluminum frame, completely eliminating air bypass and increasing filtration efficiency. While the filter holder is bonded to the media pack for added stiffness, the filter is stronger, more aerodynamic, and reduces filter pressure drop.
The filter’s mini-pleated design enables high air flow rates while maintaining a small footprint, making it ideal for use in cleanrooms where space is limited. Additionally, the pleated design increases the surface area of the filter, allowing it to capture more particles and prolong its life.
