What are some ways to maintain your high efficiency filters

Maintaining the filter is a very important issue, so how can we maintain the filter? Let's first understand what is the filter: the filter is mainly used to capture particles of dust and various suspended matters below 0.3um. Adopting ultra-fine glass fiber paper as filter material, offset paper, aluminum film and other materials for the split plate, and the outer frame of the filter is made. Each unit has been tested and is characterized by high filtration efficiency, low resistance and large dust holding capacity.

How are filters maintained?

1. Before the filter is installed, it is not allowed to tear or open the packing bag or packing film by hand, and the air filter should be stored in strict accordance with the direction standard labeled on the filter packing box; in the process of handling the air filter, it should be gently taken and put down to avoid violent vibration and collision.

2. The transportation and storage of the filter should be shelved in accordance with the direction of the manufacturer's sign. During transportation, it should be held lightly, prevented from violent vibration and collision, and not forced loading and unloading.

3, before the installation of the filter, it is necessary to unpack the packaging at the installation site for appearance inspection, including: whether there is any damage to the filter paper, sealant and frame; whether the side length, diagonal and thickness dimensions are in line with the requirements; whether the frame has burrs and rust spots (metal frame); whether there is any product qualification certificate and whether the technical performance is in line with the design requirements. Then check in accordance with standard methods, qualified should be installed immediately.

4, for the filter, the installation direction needs to be correct: with the corrugated plate combination filter in the vertical installation, the corrugated plate is perpendicular to the ground; the filter in the vertical connection with the frame, is strictly prohibited to leakage, deformation, breakage and leakage of glue, etc., after the installation, need to ensure that the inner wall is clean and free of floating dust, oil, corrosion and sundries, etc. ...

5, test method: observation or white silk cloth wipe check.

6. Before the filter is installed, the clean room needs to be cleaned and wiped clean, and if there is any accumulation of dust inside the purified air-conditioning system, it should be cleaned and wiped clean again to meet the cleaning requirements. If the filter is installed in the technical mezzanine or ceiling, the technical layer or ceiling should also be cleaned and wiped.

7, cleanliness level equal to and higher than 100 level clean room with the filter, before installation should be in accordance with the specified method of leakage detection, and meet the specified requirements.

8, for the filter, when the resistance value of the filter is greater than 450Pa; or when the airflow velocity out of the air surface down to a lower limit, even after the replacement of coarse and medium effect filters, the airflow rate can not be adjusted; or when the filter surface can not be repaired leakage, are required to re-replace a filter; if there is no such conditions, generally can be used in accordance with the environmental conditions, 1 If there is no such condition, the filter can be replaced once every 1-2 years according to the environment conditions.

9, filter leakage detection methods, particle counter sampling head needs to be extended into the exhaust air filter connected to the exhaust air static pressure box (or pipe) (which is different from the air supply filter scanning leakage detection, because the air supply filter leakage detection side is exposed to the room, while the exhaust filter leakage detection side of the deep in the static pressure box or pipeline) can be in the exhaust filter leakage detection side of the scanning leakage detection in the above specified methods.
