W-shaped V-shaped combination typeHigh efficiency filter, Specification and dimensions of W-shaped V-shaped combined high-efficiency filter.
The combined high-efficiency filter is called a W-type combined high-efficiency filter or a V-shaped combined high-efficiency air filter. The combined high-efficiency filter is also called a high air volume/W-type/V-type filter. The frame of the combined high-efficiency filter is divided into plastic frame, galvanized frame, aluminum frame, stainless steel frame, and commonly used plastic frame combined high-efficiency filters.

W-shaped V-shaped combined high-efficiency filterSuitable for various processes in research and production departments that require cleanliness levels below 100000 (<0.5 μ m dust particles). Due to its excellent bacterial filtration performance, this filter is particularly suitable for the pharmaceutical industry, biological laboratories, hospital operating rooms, food industry, cosmetics industry, etc. It also has a good effect on air purification in offices and hotels. Therefore, for the above situations, this filter can be used as the final filter. It can ensure cleanliness requirements of over 100000 levels.

Construction characteristics of W-shaped V-shaped combined high-efficiency filter：
a partition
Corrugated aluminum foil or paper separators can accurately maintain the spacing between pleats Maximize the utilization of filter media with minimal resistance In corrosive environments, ethylene coated separators can be used Cutting the edge of the partition can prevent damage to the filter material The aluminum foil thickness is 0.03mm and the ripple height is 4mm, which can fully guarantee the area of the filter material and the lightweight of the filter.
sealant
Seal the filter material completely with adhesive within the frame to prevent side leakage around it The sealing layer completely seals the edges and partitions of the filter material It seals all channels that may experience leakage. Enlarged image display: The polyurethane adhesive used in the standard H series filter penetrates between the filter materials to prevent the formation of gaps Polyurethane has a soft and elastic texture, which can effectively prevent cracking and damage to the filter material during transportation due to vibration.

Characteristics of W-shaped V-shaped combined high-efficiency filter frame:
Wooden - using (18mm) or 16 (mm) thick pressed boards and plywood frames, with glue and self tapping shock-absorbing nails used at the joints to ensure their firmness Metal frame, including galvanized steel sheet stainless steel. Various metal materials such as aluminum profiles
Sealing gasket
Closed cell EVA sealing gasket can be used for dry and airtight sealing to prevent filter leakage, with a standard width of 18mm and a thickness of 6mm. Silicon sealing gaskets can also be used, which can be efficiently formed using polyurethane foam without partitions. The foaming machine runs on the XY axis and automatically, resulting in a very good sealing effect.
Wedge-shaped fold layer
The filter material is folded 180 degrees on both sides to form a wedge-shaped pleated layer. When the filter material is bent, there are two indentations, which form a wedge-shaped box folded layer at the end of the partition. The wedge-shaped box folded layer can prevent the filter material from being damaged. Some filter manufacturers use single indentation or roll mark filter media pleats, or even simply fold them manually. In this inert state, the filter media is easily damaged by the sharp folds of the corrugated partition. Or damage the filter paper during excessive handling.

W-shaped V-shaped combined high-efficiency filter material parameters：
The HV series Pu material is a high-density paper made of ultrafine glass fibers. Pu material pleats are used to maximize the effective filtration area of the material, thereby reducing the filtration rate of the filter material. This is quite important for high-efficiency filters Imported H&V3 wave fiber filter material has waterproof and flame retardant properties and can be used for high temperatures of 1000 ° F (538 ℃);
1. Box type high air volume high-efficiency filter without partition
2. Large filtration area, low resistance, and long service life.
3. Standard galvanized steel frame, stainless steel frame can also be provided.
4. Install a 25mm thick flange frame.
5. Continuous operation with a maximum temperature of 80.C.
6. Test each unit before leaving the factory.
7. Filtration efficiency: H11, H13, H14 (EN1822).

Service life of W-shaped V-shaped combined high-efficiency filter：
The value of the W-type V-type combined high-efficiency filter for clean rooms in operation is not high, and the total output value may be less than a few hours for users. However, the risk and indirect cost of replacing the end high-efficiency filter will be high. When replacing the combination high-efficiency filter, production must be stopped, and the loss of production can only be calculated by the owner themselves. This loss is definitely higher than the cost of spare parts for the filter.

Replacing a combination high-efficiency filter is a very careful operation, as anything in the cleanroom can be expensive, and damaging one component can result in losses higher than the cost of all filters.

After replacing the combined high-efficiency filter, it needs to be inspected by professionals, and sometimes the air conditioning system needs to be debugged and tested for a period of time. The cost of testing, debugging, and trial operation, when added together, may be comparable to the price of the filter. Smart homeowners always hope to extend the service life of combined high-efficiency filters as much as possible, not to save a few dollars on filters, they want to avoid a lot of trouble caused by replacing filters.

The most fundamental way to extend the service life of high-efficiency filters is to block dust in the pre filter. Replacing pre filters generally does not require production stoppage or debugging, so experienced homeowners will spend their attention and money on pre filters and intermediate protection level filters.

For 10K and 100K cleanrooms, G4 filters can be used for pre filtration, and F8 filters (colorimetric method 95%) can be used for intermediate filtration. In this way, the service life of the end high-efficiency filter can generally reach 5 years.

The F8 filter is the most common pre filter for non-uniform flow cleanrooms in both foreign and domestic new projects. In some cases, the regulation of the service life of high-efficiency filters is not based on considerations of resistance, but on other factors.

If there is hydrofluoric acid in the factory building and the workshop air conditioning is not a brand new air system, the glass fiber filter paper in the high-efficiency filter will be corroded by the return air. For safety reasons, the high-efficiency filter must be replaced regularly.

Some large pharmaceutical factories replace high-efficiency filters after the rainy season every year to prevent any possible fungal contamination on the filters. Some biological laboratories and laboratories dealing with hazardous materials may require the use of new high-efficiency filters for reliability before carrying out a new important project.

W-shaped V-shaped combined high-efficiency filter replacement cycle：
The lifespan of a combined high-efficiency filter is generally over 2 years; But in order to protect the combination high-efficiency filter, which is a high-level filter used and ensure the safe operation of the clean room, many smart homeowners replace the initial efficiency every month, and replace the medium efficiency and sub high efficiency (or choose high efficiency as the protective filter in the last section of the wind cabinet as mentioned earlier) every three months. This can ensure that the high-efficiency filter has a service life of more than 5 years (even 10 years). Moreover, because the resistance of the new filter after replacement is small, the air conditioning load is greatly reduced, and the cost of filter replacement is much lower than the electricity cost required for air conditioning operation. Frequent replacement of the front pre filter actually allows the air conditioning to operate under low resistance load, saving a lot of electricity costs;
