You must be very curious about some of the installation specifications for high efficiency filters, right? Then today by the editor to introduce you to this knowledge, I hope that through our introduction, can bring you some help.

1. The size of the air supply outlet of the high-efficiency filter must meet the design requirements and should be cleaned before installation. For the air supply outlet that needs to install and replace high-efficiency filters in a clean room, a sealing gasket should be added to the joints between the flap of the air outlet and the ceiling plate. For the installation and replacement of high-efficiency filters in the technical mezzanine, short pipes should be pre-buried with the civil construction before installation, and the cracks between the short pipes and the ceiling board must be sealed if any. The air outlet shall not be installed if the surface coating is damaged. The air outlet should be connected with the duct immediately after installation, and the open end should be sealed with plastic film and tape.

2. Before installing the high-efficiency filter, the clean room must be cleaned and wiped in many ways to meet the cleaning requirements. If the high-efficiency filter is installed in the technical sandwich or ceiling, the technical sandwich or ceiling should also be cleaned and wiped in various ways.

3, clean room and clean air-conditioning system to meet the cleaning requirements, clean air-conditioning system must be test run. Continuous operation of more than 12h, again clean, wipe the clean room immediately after the installation of high-efficiency filters.

4. The transportation and storage of high-efficiency filters should be set aside in accordance with the direction of the manufacturer's logo. During transportation, it should be lightly held and put down to prevent violent vibration and collision.

5. Before installing the high-efficiency filter, the packaging must be unpacked 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 accordance with the requirements; whether there are any burrs and rust spots on the frame (metal frame); and whether there is a product certificate of conformity and whether the technical performance meets the design requirements. There is no product certification, whether the technical performance meets the design requirements. Then leak detection. Qualified by the inspection and leakage detection should be installed immediately. Installation should be based on the size of the resistance of each filter for reasonable deployment, for unidirectional flow, the same air outlet or air supply surface between the filters, each rated resistance and the average resistance difference should be less than 5%. cleanliness level is equal to and higher than the high efficiency filters of class 100 clean room.

6. The frame for installing the high-efficiency filter should be flat. The allowable deviation of the flatness of the installation frame of each high-efficiency filter is not more than 1mm.

7. When the sealing between the high-efficiency filter and the frame adopts the methods of sealing gasket, self-adhesive, negative pressure sealing, liquid tank sealing and double-ring sealing, it is necessary to wipe the surface of the packing, the surface of the filter border and the surface of the frame and the liquid tank clean.

8, the use of gasket, the thickness of the pad should not exceed 8mm, compression rate of 25% ~ 30%. the use of liquid tank sealing, the liquid level in the liquid tank to meet the design requirements, the framework of the joints shall not have seepage. When double ring seal is used, don't block the eyelet on the ring cavity when pasting the seal; both double ring seal and negative pressure seal must keep the negative pressure pipe unobstructed.

9. When installing the high-efficiency filter, the arrow on the outer frame should be consistent with the direction of airflow. When it is installed vertically, the crease seam of the filter paper should be perpendicular to the ground.

Usually, there are many ways for us to buy filtration equipment, so what are the methods and points of attention to buy a good filtration equipment?

1, look at the appearance of the color: the current domestic and foreign ventilation filter set of colors, 7035, 7033 two off-white accounted for 90% market, very few customers need black, orange, yellow, need to be customized. If the color is close to the natural color of milk, indicating the use of primary materials, the relative cost will be higher; if the color is close to the color of the concrete road, indicating the addition of secondary materials (such as recycled mineral water bottles), or even tertiary materials (such as recycled toys of poor quality), the relative cost is also lower. Secondary materials will make the product color darker, uneven color, and the product is easy to break.

2, look at the middle of the filter fiber: ventilation filter group dust core components are fiber mesh. High-quality fiber density uniformity, soft; shoddy fiber feel rough, and even have a side like film paper, ventilation, dust resistance is very poor.

3, look at the hanging fan prism thickness: in order to fan safety and fan rotation after the vibration of less sound, taking into account the size of the fan, the requirements of 803, 804 prism thickness of more than 2MM (including), 805, 806 prism thickness of more than 3MM (including). And many manufacturers in order to reduce costs, the prism are reduced by about 1MM, so that the quality of the entire product has dropped significantly.

4, look at the nut of the package column: in order to install the fan nut will not be exposed, the lower level of molding masters will make the nut package column larger, so that the installation of the fan nut put inaccurate, resulting in the fan can not be mounted, and a waste of raw materials and affect the aesthetics of the product manufacturers. While the precision mold of the nut package column and nut matching consistent, which also makes the fan can be properly installed in place.
