Chengdu W-type H10 sub high efficiency filter with large air volume plastic frame design for cleanroom use

Description :

  The Chengdu W-type H10 sub high efficiency filter is an air purification component designed specifically for high air volume ventilation systems, mainly addressing the filtration needs of small particulate matter in industrial cleanrooms and large HVAC systems. This sub efficient filter adopts a unique W-shaped wave structure folding design, effectively increasing the filtering area, thereby achieving high dust holding capacity while maintaining low operating resistance. It is usually installed before the high-efficiency filter as a pre filter, which can significantly extend the service life of the end high-efficiency filter, reduce overall operation and maintenance costs, and is suitable for typical working environments with high air quality requirements but without the need to achieve a hundred level cleanliness.

  The core specifications of the Chengdu Plastic Frame H10 sub high efficiency filter are reflected in its filtration efficiency and structural materials. H10 level means that its filtration efficiency for 0.5 μ m particles is typically between 85% and 95%, in accordance with EN 1822 or similar international standard classifications. The outer frame is made of high-strength engineering plastic injection molding, which has the characteristics of corrosion resistance, light weight, and good sealing, avoiding the risk of corrosion and pollution that may occur in the metal frame. The filter material is mostly high-quality glass fiber filter paper or synthetic fiber, which is fixed in the frame with hot melt adhesive or polyurethane sealant to ensure no leakage. The overall structure is compact, with standard thicknesses of 292mm or 365mm, suitable for various standard duct sizes, and has good mechanical strength and moisture resistance.

  When selecting Chengdu high wind capacity sub high efficiency filters, it is important to consider air volume matching and installation space. Compared to flat filters, W-shaped structures can provide greater processing air volume on the same windward side, making them suitable for main air ducts with high fan power and wind speed. If the on-site space is limited, a thinner model should be selected; If pursuing a longer replacement cycle, deep pleated or high-capacity versions should be chosen. Please note that sub high efficiency filters are not suitable for environments containing a large amount of oily mist or viscous dust, as these conditions can easily cause the filter material to clog too quickly. Compared with medium efficiency filters, its accuracy is higher; Compared with high-efficiency HEPA filters, it has lower resistance and lower cost, making it an excellent cost-effective choice for intermediate filtration.

  When installing the Chengdu W-type H10 sub high efficiency filter, it is necessary to confirm that the airflow direction is consistent with the box identification, and reverse installation is strictly prohibited. The connection between the frame and the air duct should be sealed with gaskets or treated with glue to prevent unfiltered air from bypassing and leaking. In daily maintenance, it is recommended to regularly monitor the pressure difference before and after the filter. When the initial resistance increases to the final resistance (usually 400-450Pa), it indicates that the filter element is saturated and must be replaced. It cannot be cleaned and reused. When storing, it should be placed in a dry and ventilated place to avoid moisture that may cause the strength of the filter paper to decrease or mold. Regularly inspect the framework for any deformation or damage to ensure sealing integrity, in order to maintain stable purification efficiency and system energy balance.
