What is the structure and material of the replaceable one-piece high-efficiency filter?

Replaceable one-pieceHigh Efficiency FilterWhat is the structure and material of the

Replaceable one-pieceHigh Efficiency FilterAdopting the built-in high efficiency filter without partition in the box with air duct interface, due to the small volume, light weight and good structural sealing. It is suitable for dry sealing ceiling in clean room.

Replaceable one-piece high-efficiency filter construction:

1. Box with duct connection (galvanized sheet frame/aluminum zinc-coated sheet).
2. High efficiency filter without partition.
3 Duct connection diameter: (300/250/200 available).
4. External insulation cotton.

Replaceable One-Piece HEPA Filter Product Features:

1. Small volume, light weight, good structural sealing, suitable for cleanroom dry seal ceiling.
2. Easy to replace and save cost.
3. The replaceable integrated high-efficiency filter consists of a static pressure box and a non-spacer high-efficiency filter, adopting aluminum profiles to make the static pressure box and a non-spacer high-efficiency filter built into the box. It has the advantages of strong ventilation, beautiful appearance, easy installation and replacement, simple maintenance, low investment, light weight, thin thickness and so on. Sometimes, when the clean room is limited by the height of civil construction or must adopt compact design, replaceable integrated high-efficiency filter can be used.

W-type and V-type combined high-efficiency air filter structure and features

Combined high-efficiency filters are large air volume/W-type/V-type filters, combined high-efficiency filters with large air volume, combined high-efficiency filter frame: plastic frame, galvanized frame, aluminum frame, stainless steel frame, commonly used combined high-efficiency filters with plastic frame.

Combined high-efficiency filter structure and partition characteristics: combined high-efficiency filter partition corrugated aluminum foil partition or paper partition can maintain the pleated layer spacing. Maximum utilization of filter media with low resistance. In corrosive environments, vinyl coated partitions can be used. The chopped edges of the partitions prevent breakage of the filter media. Aluminum foil thickness of 0.03mm and corrugated height of 4mm can fully guarantee the area of filter material and the light weight of the filter.

Combined HEPA filter sealant introduction: completely seal the filter media with adhesive inside the frame to prevent side leakage around. The sealing layer completely seals the edges of the filter media and the partition. That is to say, all possible leakage channels are sealed. Enlarge this image to see: The polyurethane adhesive used in standard H-Series filters penetrates between the filter media to prevent gaps from forming. The polyurethane has a soft, flexible texture that prevents cracking of the adhesive and vibration damage to the filter media during transportation.

Combined HEPA filter frame wood - using (18mm) or 16 (mm) thick pressed board and plywood frame, the joints are connected by glue and self-tapping anti-vibration nails to ensure its firmness. Metal frames, including galvanized steel. Stainless steel. Aluminum profiles and other metal materials. Combined high-efficiency filter sealing gasket: closed cell EVA sealing gasket can be used for dry airtight sealing to prevent side leakage of the filter, the standard is 18mm wide and 6mm thick. Silicon sealing gasket can also be used, no partition high efficiency can be formed using polyurethane foam as a whole, foam machine to go XY axis, automatic operation, sealing effect is quite good.

The two sides of the filter material are folded by 180 degrees to form a chiseled pleated layer. Two indentations are made when the filter media is bent, so that it forms a wedge-shaped box pleat layer at the end of the partition, and the wedge-shaped box pleat layer can prevent the filter media from breaking. Some filter manufacturers use a single indentation or roll mark media pleat layer, or even simple manual origami, in which case the media is easily damaged by the sharp folded top of the corrugated bulkhead. Or the filter paper may be damaged during excessive handling.
