High-quality filter media, reasonable design, high dust holding capacity and low resistance
Cleanroom Filtration Primary Efficiency Plate Air Filter
Primary efficiency filter is used in combination with cleanroom HEPA filters to prevent premature replacement of cleanroom HEPA filters due to dust accumulation, thus extending the service life of cleanroom HEPA filters.
High-quality filter media, reasonable design, high dust holding capacity and low resistance.
The high-quality fluffy filter media is used. The filter media is a special mixture of non-woven fabric and synthetic fiber, with a special contour pleat design to provide a larger dust holding capacity and increase the utilization of the filter media. A reasonable number of filter pulp pleats increases the effective use area of the filter and reduces the resistance at the same time.
Sturdy double-layer moisture-proof paper frame structure
Cleanroom filter adopts moisture-proof paperboard frame, and the filter paper is bonded to all the connection points in the frame, which has a solid and reliable structure and ensures that the filter will not be deformed or damaged under the poor usage environment. Supplemented with filter media support mesh inside, the filter enjoys compact structure, light weight, easy installation and disassembly.
Clean room air filter is widely used in the primary-efficiency clean roomfiltration section of various industrial, commercial, and residential building ventilation systems for its low resistance, high dust holding capacity, easy installation and disassembly, and undergoing UL900 certification.
