Hepa filter sealing method

Hepa filter sealing method 
1. and packing sealing method contact, the sealing method in the use of packing has a solid sealing gasket, the solid sealing gasket is usually adopted mechanical compression bolt mother material sealing method.
The compression amount of the rubber sheet is usually 30% to 50%. This sealing method is also a common sealing method for clean rooms.
2, the adoption of negative pressure leakage sealing method, positive pressure space in the contaminated air through human intervention to the negative pressure space outside the work area, to ensure that the work area is free of contamination.
3, liquid tank sealing method, this method in the tank frame, injects a high degree of non-Newtonian sealing liquid, the mouth of the Hepa filter into the sealing liquid, Hepa filter blocks the air on both sides of the channel.To achieve the purpose of sealing.

The HEPA filter is mainly used to capture particulate dust and various suspended solids below 0.5um. Adopt ultra-fine glass fiber paper as filter material, adopt offset paper, an aluminum film, and other materials as dividing plates, and glue with aluminum frame aluminum alloy.
1. Before installation, the Hepa air filter shall not be torn or opened by hand in the bag or packaging film; the air filter shall be stored strictly by the direction marked on the Hepa filter packaging; care shall be taken to gently avoid violent vibration and collision when handling the Hepa air filter, and loading and unloading shall not be agreed.
2. Correct installation direction of Hepa filter: When the vertical filter is installed with a corrugated plate, the corrugated plate is perpendicular to the ground; Leakage, deformation, damage, and leakage of the connection between the vertical and frame of the filter are strictly prohibited. After the installation of glue, etc., the inner wall is clean and free from dust, oil, rust, and debris.
3. Thoroughly clean and sanitize the clean room before installing the HEPA filter without a separator. If there is dust in the air conditioning system, it should be cleaned and wiped down again to meet the cleaning requirements. If HEPA filters are installed in the technical mezzanine or ceiling, the technical mezzanine or ceiling should also be thoroughly cleaned and wiped clean.
4. Before installing the HEPA filter, unpack the filter at the installation site and carry out an external inspection, including damage to the filter paper, sealant, and frame; the required edge length, diagonal and thickness dimensions; the frame with or without burrs and rust spots (metal frame); the existence of product certificates and whether the technical performance meets the design requirements.
5. Hepa filter, cleanliness equal to or higher than class 100 clean room.
