How to install the filter

In the transportation, installation and use of the process, according to the requirements in order to ensure the use of results. A variety of filters in the use of a period of time, because the filter surface to collect dust, so that the filter efficiency and resistance to drop, affecting the cleanliness of the air, this time need to be replaced in time filter.
For high humidity, high temperature environment, the filter must be selected high temperature, high humidity filter paper and partition board, frame material to meet production requirements. Biological clean room and medical clean room, must use the metal frame filter, and its surface should not rust, does not allow the use of wood frame filter, in order to prevent bacteria, affecting product yield.
For the above filter, if the filter before and after the differential pressure gauge or differential pressure sensor, the coarse filter, when the pressure difference is greater than 250Pa, you must be replaced; for the efficiency filter, the pressure is greater than 330Pa , Must be replaced; for sub-efficient filter, when the pressure difference is greater than 400Pa, it must be replaced, and the original filter can not be reused; for high efficiency filter, when the filter resistance is greater than 450Pa; The airflow velocity can not be increased even when the coarse and medium efficiency filter is replaced, or the new high efficiency filter is replaced when the surface of the high efficiency filter can not be repaired and leaked, and the air flow speed is reduced to a minimum. In the absence of the above conditions, generally according to the use of environmental conditions, 1-2 years replacement time.
In order to give full play to the role of filters in the selection and use of the process, the filter face wind speed, rough efficiency, efficiency filter should not be greater than 2.5m / s, sub-high efficiency filters and high efficiency filter should not be greater than 1.5m / S, this will not only help to ensure the efficiency of the filter, but also can extend the filter life, cost savings. In the equipment operation, generally do not replace the filter; if the filter has to replace the replacement period can not stop, then only allow In the case of non-stop fans to replace coarse and medium efficiency filter; sub-high efficiency filter and high efficiency filter must stop after the air before replacement; filter and connecting frame between the gasket must be tight, no leakage to Ensure the filtering effect
