Several factors that affect the price of high temperature HEPA filter.
High-temperature compressed air filters are widely used in industries such as pharmaceuticals, spray workshops, tunnel ovens, and high-temperature resistant clean pipes. These industries require high-temperature HEPA filters, which are generally classified into two categories: 250-degree and 400-degree high-temperature filters. Therefore, users must understand their actual needs when choosing a filter. If you only need to withstand temperatures of up to 250 degrees but purchase a 400-degree filter, the cost will be much higher, making it neither economical nor practical.
Here are the main reasons for the price of high-temperature filters:
Function: High-temperature and high-efficiency filters are primarily used to capture particles of 0.3 micrometers and various suspended contaminants.
Place of Use: These filters are used in high-temperature sterilization and purification equipment, including the final step in high-temperature air supply systems and high-temperature clean ovens.
Filter Material: Ultra-fine glass fiber paper is used as the filter material, and each air filter must be checked and leak-tested individually. These filters are characterized by high filtration efficiency, low resistance, and a large dust-holding capacity.
Temperature Resistance: High-temperature and high-efficiency filters can be used in high-temperature situations, but the degree of temperature resistance varies. This affects the filter's maximum instantaneous temperature, which can reach up to 300 degrees. It's important to choose products based on the specific production environment.
Frame Material: The frame of high-temperature HEPA filters includes options such as aluminum alloy, stainless steel 304, or galvanized steel. The outer frame material directly influences the price of the filter. Galvanized steel frames cannot withstand condensate produced during heat and cold exchanges, which can cause long-term damage to the filter.
Sealing Gasket: High-temperature HEPA filters use special high-temperature sealing gaskets, which are significantly more expensive than those used in ordinary high-efficiency filters.
Additionally, if a user in the chemical industry is selecting high-temperature air filters, it is important to determine whether the equipment has specific requirements for silicon. Generally, 250-degree HEPA filters use glue containing silicon. Silicon is divided into organic and synthetic types. Organic silicon may react chemically in certain industries and can produce a pungent odor. Cheap filters often use organic silicon, whereas reputable manufacturers use standard synthetic silicon to ensure efficiency and safety. For 400-degree high-temperature air filters, ceramic glue made from powder and aqueous solutions is used. It is recommended to use ceramic glue from the American Eunice brand, which is environmentally friendly and odorless. Different costs reflect the use of different materials. Users should select products based on their specific needs and conditions.
