250 ℃ VS 400 ℃ High Temperature Resistant HEPA Filter
250 ℃ VS 400 ℃ High Temperature Resistant HEPA Filter
The difference between 250℃ and 400℃ high temperature resistant high efficiency filter
250℃ high temperature resistant high efficiency filter
The 250°C high temperature resistant high efficiency filter uses a partition design. The corrugated partition can accurately maintain the spacing of the pleats, and maximize the use of filter materials with minimal resistance.
The filter material of 250℃ high temperature resistant high efficiency filter is folded 180 folds on both sides to form a wedge-shaped pleated layer. When the filter material is bent, there are two indentations, making it open at the end of the partition into a wedge-shaped box-shaped pleated layer. The box pleated layer can prevent the filter material from being damaged.
250℃ high temperature resistant high efficiency filter operating conditions:
250℃ high temperature resistant high efficiency filter filter material: ultra-fine glass fiber filter paper sealant: red silica gel (250~280℃) ceramic glue (350~400℃)
250℃ high temperature resistant high efficiency filter frame material: aluminum profile/aluminum plate/galvanized iron/stainless steel below 250℃, galvanized iron frame or stainless steel frame must be selected above 250℃. Separator: 0.035mm thick aluminum foil
250℃ high temperature resistant high efficiency filter sealing tape: silicone plate (250~280℃) PTFE tape (350～400℃)
Filtration efficiency: 99.97%～99.995% @0.3μm Maximum use temperature: 250~280℃ 350～400℃
Use the highest humidity: 80%;
Applicable places and application fields of 250℃ high temperature resistant high efficiency filter:
1. High cleanliness occasions such as aerospace, electronics, semiconductors, chips, biopharmaceuticals, hospitals, food processing, etc.
2. Terminal of air-conditioning ventilation system (end filtering and hot-air high-temperature oven, oven).
3. The operating room of the hospital, hospital, biopharmaceutical, laboratory, circuit board, microelectronics, optics, LED photoelectric, QS food processing or purification equipment requires a clean working environment with high temperature at the end.
400℃ high-temperature high-efficiency filter
The 400℃ high-temperature high-efficiency filter is mainly made of high-quality, high-performance high-temperature-resistant ultra-fine glass fiber filter paper as the filter medium, aluminum foil corrugated sheet as the spacer, SUS304 stainless steel plate as the frame, and sealed and assembled with high-temperature sealant.
The 400℃ high temperature high efficiency filter is characterized by high filtration efficiency, low resistance and good high temperature resistance.
The characteristics of 400℃ high-temperature high-efficiency filters are mainly used in equipment and systems that require high-temperature air purification such as ultra-clean ovens.
Application fields of 400℃ high temperature and high efficiency filter:
1. High cleanliness occasions such as aerospace, electronics, semiconductors, chips, biopharmaceuticals, hospitals, food processing, etc.
2. The terminal of the air-conditioning ventilation system (end filtering and hot-air high-temperature oven).
3. High temperature paint spray line.
4. High clean baking booth.
5. High purified baking box.
6.Food baking booth or room.
7. Use with high temperature equipments to kill the germ or virus, such as pharmaceutical factory.
8. Ventilation system with high fire resistant requirement and high temperature operating environment
The limit size of 400℃ high temperature and high efficiency filter: width≤1220mm, length≥1220mm, thickness 50~300mm.
The corrugated baffle can accurately maintain the distance between the pleats and maximize the use of the filter material with minimal resistance.
The high temperature resistant high efficiency filter filter material is folded 180 folds on both sides to form a wedge-shaped pleated layer. When the filter material is bent, there are two indentations to make it open into a wedge-shaped box pleated layer at the end of the partition. The pleated layer can prevent the filter material from being damaged.
Features of 400℃ high temperature and high efficiency filter:
1. The high-efficiency filter with high temperature resistance to 400℃ uses a partition design. The corrugated partition can accurately maintain the distance between the pleats and maximize the use of filter materials with minimal resistance.
2. The filter material is folded 180° on both sides to form a wedge-shaped pleated layer. When the filter material is bent, there are two indentations, making it open at the end of the partition into a wedge-shaped box pleated layer and a wedge-shaped box fold layer. It can prevent the filter paper from being damaged.
3. Usually used in high-temperature clean ovens, high-temperature sterilization equipment and high-grade purification equipment, etc.
4. Mainly used to capture 0.3um particle dust and various suspended solids.
5. Use place: high temperature sterilization production clean equipment, high temperature air supply at the end of purification equipment with high cleanliness requirements, high temperature resistant clean oven purification equipment
6. Filter material: Ultra-fine glass fiber paper is used as the filter material. Each unit is tested by the nano-flame method. It has the characteristics of high filtration efficiency, low resistance, and large dust holding capacity.
7. It can be used in high temperature resistant occasions, but the glue used is different for different temperature resistant degrees, which also directly affects the main reason for the price of high temperature resistant high efficiency filters.
8. The outer frame is a stainless steel outer frame or a galvanized frame. The raw materials of the outer frame are also one of the factors that directly cause the price of the high-efficiency filter.
9. High temperature resistant high-efficiency filters use high-temperature special rubber gaskets, which are significantly more expensive than the rubber gaskets used in ordinary high-efficiency filters.
