II.Advantage of the HEPA Filter High Temperature 250 Degree
● Red silicon gasket and silicon sealant help achieve perfect air-tight in high temperature conditions.
● SAF 250 ℃ high temperature resistant sealant uses chemically synthesized inert silicon, which has good stability, no odor, and fast curing speed (relatively, it takes 3-7 days for organic silicone to fully cure). It overcomes the pungent odor of organic silicone and will not cause secondary pollution to painting, ultrasonic, pharmaceutical and other industries.
● The high-temperature HEPA filter is especially for pharmaceutical, chemical, and ultrasonic, micron-electronics industries. The special silicone seal material can beat this high temperature and keep good performance airtight. the silicone keeps safe during high temp and won't release other/dangerous elements.
● The metal mesh placed on both inlet and outlet side protects filter media from damage.
● The stainless steel 201 or 304 frame can withstand a high temperature, also it is quite strong to make sure the HEPA filter is robust and stable.
● Glass fiber filter media are separated by a corrugated aluminum spacer to form tunnels that airflow passes through.

IV.Typical Application of the HEPA Filter High Temperature 250 Degree
● The high temperature HEPA filter is mainly applied in the food and pharma industries, that application required an ultra-clean oven to dry air and also needs a HEPA filter to purify the air.
● In the production of formaldehyde, high temperature filters are required. However, the use of unsuitable materials (Silicone sealant) can lead to the failure of the catalyst required for production. Our special sealing material can effectively solve this problem.
● In some special industries such as semiconductors, silicon filters are not allowed. Our special silicone-free series can be used in the above places.
V.FAQ
Q1How efficient are high-temperature HEPA filters?
-High-temperature HEPA filters maintain the same efficiency as standard HEPA filters, capturing 99.97% of particles as small as 0.3 microns. The difference lies in their ability to perform in extreme heat.
Q2Can high-temperature HEPA filters handle corrosive environments?
-Some high-temperature HEPA filters are designed with corrosion-resistant materials (e.g., specific stainless steel alloys) for use in corrosive environments. Always check the filter specifications to ensure compatibility.
