First, product features and uses
The general high-efficiency filter (hereinafter referred to as the filter) is a purification device, which has a particle filtration efficiency of 99.99% for particles in the air of 0.12 UM, and is mainly used for high cleanliness of electronics, medicine, food, precision instruments and cosmetics. Industry. It must be transported, stored and installed in strict accordance with this requirement to ensure that the filter is used correctly.
Second, transportation and storage
1. During transportation, the filter should be placed in the direction of the box to prevent the filter material, partitions, etc. from falling off and being damaged by vibration.
2. During transportation, it must be transported in the diagonal direction of the box. The transporter should take care to prevent the filter from slipping during transportation and damage the filter.
3. When loading, the stacking height is up to three layers. Consolidate the rope when transporting. When the rope crosses the corner of the box, a soft object is used to separate the rope from the box. Protect the cabinet.
4. The filter should be placed on a dry surface in the direction of the box identification. No external force of more than 20 kg can be applied to the filter.
5. The storage location should be an environment with small changes in temperature and humidity, clean, dry and good ventilation system.
6. When storing and placing the filter in the warehouse, use the mat board to separate the filter from the ground to prevent the filter from getting wet.
7. The stacking height should not exceed three layers to avoid damage when the filter is over-stressed and deformed and transported again.
8. If the storage period is more than three years, it should be retested.
Third, unpacking
1. Remove the tape from the outside of the box in a flat place, open the bag, take out the pad, turn the case so that the filter is placed on the ground, and then pull the carton up.
2. After unpacking, during the handling process, both hands and other objects must not collide with the filter material. If the filter material is accidentally touched, it should be scanned again even if it is visually invisible.
Fourth, installation and adjustment
1. The filter should be installed in a normal temperature, normal pressure, and normal humidity environment. If you need to install in a special environment (such as high temperature, high humidity), please use our special high efficiency filter products. If the working conditions are bad, the filter life will be shortened and it will not work properly even after installation. Before installation, the appearance of the filter should be tested for deformation, damage, and damage to the filter material. If any of the above conditions are found, please contact our company in time.
2. The sealing between the filter and the mounting frame (or the box) must be paid attention to during the installation process. The pressing bolt should preferably be one-third of the thickness of the sealing gasket. In order to ensure the sealing performance of the filter and the installation box, it is recommended to use the gasket provided by our company. (When using a high temperature filter, be sure to use the high temperature gasket specially supplied by our company)
3. When replacing the filter, be sure to wipe the inner wall of the static pressure box or the air supply pipe thoroughly to prevent the rust and dust particles on the wall from falling on the filter, causing the filter to be damaged.
4. When installing, be sure to pay attention to the airflow direction of the filter. You can install it according to the wind direction indicator “↑†of the filter label. The direction of the arrow is the filter outlet.
Fifth, service life and maintenance
1. Under normal circumstances, when the final resistance of the filter is twice the initial resistance, it should be replaced.
2. The cleanliness should be tested regularly on the clean area. The data to be tested should meet the design requirements of the clean plant. If the requirements are not met, the filter should be scanned and the leak tightness of the system checked. If the filter leaks, it should be replaced with rubber. When the system is used again after long-term deactivation, the clean room should be scanned.
3. In order to extend the applicable life of the filter, the primary and secondary filter should be replaced frequently during operation.
