How to properly install and maintain foldable combined air filters to reduce drag?
How to properly install and maintain foldable combined air filters to reduce drag?Proper installation and maintenance of foldable combined air filters is critical to reducing drag, and here's how:Installation aspect Choose the right location: The filter should be installed in a position where the airflow is smooth, to avoid installation in a dead corner or airflow disturbance. At the same time, close to the area where air needs to be purified to reduce pipe length and resistance. In the air conditioning system, it is usually installed at the air outlet or fresh air inlet of the air conditioning unit. Ensure installation space: Reserve enough space for the filter to facilitate installation and subsequent maintenance. At least 10-15 cm of space should be left around the filter for easy removal and replacement. Pay attention to the installation direction: Strictly follow the airflow direction marked on the filter to ensure that air passes through the filter in the correct direction. Generally speaking, there is an arrow on the outer frame of the filter, and the direction of the arrow is the direction of the airflow. If the installation direction is wrong, it will not only affect the filtering effect but also lead to increased resistance. Ensure a sealed installation: Use materials such as sealing rubber strips or gaskets to ensure a good seal between the filter and the mounting frame to prevent air leakage. Poor sealing will make some air pass directly through the gap without filtering, reducing the filtration efficiency, and may also lead to an increase in local airflow speed, thereby increasing resistance. Maintenance aspect Regular inspection: Check the appearance of the filter regularly to see if there is dust accumulation, filter material damage, deformation of the outer frame, and so on. Check at least once a month, if found problems should be handled in time. For dusty environments, the inspection frequency should be appropriately increased. Cleaning or replacement: For washable filters, when the surface is dusty, you can use a mild detergent and water to clean, and then naturally dry or dry with low-temperature air. For non-cleanable filters, when the resistance reaches 1.5-2 times the initial resistance, a new filter should be replaced in time. Prevent moisture: Avoid the filter in a humid environment to prevent the filter material from being deformed by moisture or breeding bacteria. If used in a humid environment, consider adding dehumidification equipment or choosing a filter with a moisture-proof function. Record maintenance information: Establish a filter maintenance record file, record the filter installation time, model, maintenance time, replacement, and other information, to track the use of the filter, find problems in time, and optimize. |
