The difference between high-efficiency filters without partitions and with partitions. Renhe Purification pointed out that the filter without partitions mainly uses hot melt as the separator of the filter element, which facilitates mechanized production. In addition, it has the advantages of small size, light weight, easy installation, stable efficiency, and uniform wind speed. Currently, large batches of filters required in clean factories mostly adopt partition-less structures. Partitions are highly efficient, and aluminum foil and paper are often used in folded shapes as filter element separators to form air passages. The partition board is made of high-quality kraft paper, which is hot rolled or offset paper is used as the partition board. At present, double-sided coated paper is mostly used as partitions. The main purpose is to prevent the partitions from shrinking due to the influence of cold, heat, dryness and humidity, thereby emitting particles. When temperature and humidity change, this kind of partition paper may emit larger particles, causing the cleanliness test of the clean factory to fail. Therefore, for places with high cleanliness requirements, customers should be recommended to use high-efficiency air filters without partitions. The price of foreign filters with partitions is higher than that without partitions, so there are fewer places where partitions are used in foreign countries. In addition, compared with the rectangular channel with a partition filter, the V-shaped channel without a partition filter further improves the uniformity of dust holding and extends the service life. Baffleless filters for ventilation avoid the use of metal parts, are easy to dispose of, and comply with increasingly stringent environmental requirements. Except for some special occasions with high temperature resistance and high safety requirements, filters without partitions can replace filters with partitions.
1. High-efficiency filters can be divided into: high-efficiency with partitions and high-efficiency without partitions
2. High-efficiency filters with partitions use ultra-fine fiber as filter material and are of high quality. Kraft paper is hot-rolled or made of offset paper or aluminum platinum as partitions, and is glued with a wooden frame or aluminum alloy frame. It has the advantages of high filtration efficiency, low resistance and large air volume. At present, double-sided coated paper is mostly used as the partition board. The purpose is to prevent the partition board from shrinking due to the influence of cold, heat, dryness and humidity, thereby dispersing particles. However, when the temperature and humidity change, the partition paper may emit larger particles, causing the cleanliness test of the clean workshop to fail. It is suitable for low-level non-unidirectional flow projects and various purification equipment and clean workshops. Among filters with partitions, aluminum partition filters are mainly used in high temperature or high humidity environments, while paper partition filters are used in ordinary clean environments. The air volume with partitions is relatively large, and the efficiency can only reach high efficiency. It can be used as a high-temperature-resistant filtration. The requirements for filter materials are not as strict as those without partitions.
3. The partition-less high-efficiency filter removes the corrugated partitions in the traditional structure and uses ultra-fine glass fiber as the filter material, hot melt adhesive as the partition of the filter element, and various outer frames. assembly. Suitable for strict one-way flow and high-level non-unidirectional flow clean room projects. Nowadays, Class A clean rooms generally use high-efficiency filters without partitions, and the FFU is also equipped with high-efficiency filters without partitions. Compared with high-efficiency filters with partitions, under the same air volume, they have small size, light weight, and excellent structure. It has the advantages of compactness, reliable performance, easy installation, stable efficiency, and uniform wind speed. The efficient design without partitions can achieve the highest efficiency with minimal resistance, thereby reducing operating costs. In particular, the designed hot melt adhesive can ensure the same fold spacing, ensure the passage of optimal airflow, and at the same time achieve high dust holding capacity, extending the Long service life, making full use of the filter media throughout the depth of the filter. Under the same size conditions! The amount of ventilation is different from the amount of dirt! Without partitions > With partitions.
