To ensure the filtration efficiency of filters and the cleanliness of the cleaning system, the installation of HEPA filters must comply with the requirements of the cleanroom construction and acceptance code or the design drawing.

1. Preparation before installation in order to prevent pollution of HEPA filters, the inspection and installation must be carried out after the installation of the air cleaning system is completed, the air conditioner, HEPA filter box, air duct and clean room are cleaned, and the ice energy can be carried out after the test run of each individual equipment of the air conditioning system and the stable amount of dust blown out of the air duct. Before installation, check the flatness of the filter frame or the end face of the edge mouth. The allowable deviation of flatness of the end face shall not exceed 1mm.

If the flatness of the end face exceeds the allowable deviation, only the end face of the frame installed by the filter is allowed to be modified or adjusted, and the outer frame of the filter itself is not allowed to be modified. Otherwise, the filter material or sealing part of the filter will be damaged and the filtering effect will be reduced.

2. Installation requirements: when installing a Hepa filter, ensure the airflow direction is consistent with the arrow mark on the outer box. When the high-efficiency filter assembled with corrugated plate is installed vertically, the corrugated plate must be perpendicular to the ground and not reversed. The sealing of the HEPA filter and the frame of the assembled Hepa filter generally adopts the top tight method and the compression method.
