250 ° C | 400 ° C high temperature resistant and efficient filter

250 ° C | 400 ° C high temperature resistant and efficient filterGuangzhou Zijing not only produces high-efficiency filters, but also has many purification equipment, such asAir showerCargo shower room, ultra clean workbench FFU、 Clean room, high-efficiency air supply outlet, medium efficiency filter, primary efficiency filter, etc.

High temperature resistant and efficient filter, also known as high temperature resistant air filterThe high temperature resistant and efficient filter uses red high-temperature silicone gel that can withstand 250 ℃ and black high-temperature inorganic gel that can withstand 350-400 ℃. Due to the influence of the physical properties of the glue (poor fluidity), the actual filtration efficiency of the 250 ℃ H13 high temperature resistant and efficient filter is between H12-H13; The actual filtration efficiency of H13 high-temperature high-efficiency filter at 350-400 ℃ is between H11-H12.

Due to the fact that the organic silicone and inorganic adhesives used in the 250 degree high-temperature resistant high-efficiency filter and 400 degree high-temperature resistant air filter are cured from the surface to the inside during the curing process, the thicker the injection height, the more difficult it is to cure. Under normal circumstances, the curing time of the adhesive is 3-7 days. If the high-temperature high-efficiency filter that is not completely cured is directly installed on the high-temperature equipment for normal use, it will inevitably cause phenomena such as cracking, expansion, and detachment of the adhesive from the outer frame;

Suitable locations for high-temperature resistant and high-efficiency filters:
1. High cleanliness applications such as aerospace, electronics, semiconductors, chips, biopharmaceuticals, hospitals, and food processing.

2. Terminal of air conditioning and ventilation system (end filter and hot air high-temperature oven, oven).

3. A clean working environment with high end temperature requirements for operating rooms, hospitals, biopharmaceuticals, laboratories, circuit boards, microelectronics, optics, LED optoelectronics, QS food processing or purification equipment in hospitals.

High temperature resistant and efficient filter materials and operating conditions:
Filter material: ultra-fine fiberglass filter paper;

Sealing glue: red silicone (250~280 ℃);

Aluminum profiles/aluminum plates/galvanized iron/stainless steel can be selected for frame materials below 250 ℃. Galvanized iron frames or stainless steel frames must be selected for frames above 250 ℃;

0.035mm thick aluminum foil separator;

Sealing strip silicone sheet (250-280 ℃);

The filtration efficiency is 99.97% to 99.995% @ 0.3 μ m.

Several factors that affect the price of high-temperature and high-efficiency filters:
High temperature resistant and efficient filters have a wide range of applications, such as general pharmaceutical equipment, spray painting workshops, ovens, and high-temperature clean pipelines. High temperature resistant and efficient filters are generally divided into 250 degree high temperature resistant and 400 degree high temperature resistant filters. Therefore, when choosing, users must understand their true needs. If you only need 250 degree high temperature resistant filters but choose 400 degree high temperature resistant filters, the cost will be much higher. Now, the main prices of high temperature resistant and efficient filters are listed for reference:
1. The function of high temperature resistant and efficient filters is mainly to capture 0.3um particulate dust and various suspended solids.

2. Place of use: High temperature sterilization production clean equipment, purification equipment with high cleanliness requirements, high temperature air supply at the end, and high temperature resistant clean oven purification equipment

3. Filter material: Ultra fine glass fiber paper is used as the filter material, and each unit has been tested by flame holding method, which has the characteristics of high filtration efficiency, low resistance, and large dust holding capacity.

4. High temperature resistant and efficient filters can certainly be used in high-temperature environments, but the adhesive used varies depending on the degree of temperature resistance, which directly affects the main reason for the price of high temperature resistant and efficient filters. (It is usually resistant to high temperatures, with a maximum instantaneous temperature of up to 400 degrees and a constant temperature of around 250 degrees. The selection varies depending on the production environment.).

5. The outer frame of the high-temperature resistant and high-efficiency filter is made of stainless steel or galvanized frame, and the raw material of the outer frame is also one of the factors directly affecting the price of the high-efficiency filter.

6. High temperature resistant and efficient filters use high-temperature resistant special rubber gaskets, which are significantly more expensive than the rubber gaskets used in ordinary high-efficiency filters.
It should be noted that if users in the chemical industry choose high-temperature resistant and high-efficiency filters, they must understand whether the equipment used has silicon requirements. Generally, 250 degree high-temperature resistant and high-efficiency filters contain silicon, while 400 degree high-temperature resistant and high-efficiency filters do not contain silicon. This requires special care, otherwise it may cause the produced products to be unqualified.
