Filter Media Materials
Filter Media
This is the core of the filter, determining its filtration efficiency.
Primary Material: Glass Fiber Paper
Characteristics: This is the most common and cost-effective high-temperature resistant filter media. Depending on the formulation and manufacturing process, its long-term temperature resistance typically ranges from 250°C to 400°C.
Ceramic Fiber Paper: Excellent temperature resistance, can be used long-term in environments from 500°C to 800°C or even higher. Sintered Stainless Steel Metal Fiber Felt: Temperature resistance can exceed 600°C. PTFE (Poly tetra fluoro ethylene) Membrane Laminated Media: In some medium-temperature applications (e.g., continuous operating temperature ≤ 260°C)
Separator
Primary Material: Aluminum Foil, Other Materials: Stainless Steel Foil
Sealant / Adhesive
Primary Materials: High-Temperature Silicone or Inorganic Adhesive
Frame
The frame is the structural skeleton of the filter and must be robust and heat-resistant. Primary Materials: Galvanized Steel Sheet, Aluminum Sheet, Stainless Steel Sheet (e.g., 304, 316)
Gasket
Primary Materials: Silicone Cord with Glass Fiber Sleeving, Silicone Foam Strip, Alkali-Free Glass Fiber Cord.
It is recommended that you provide your specific working environment details (such as temperature, chemical environment, efficiency requirements, etc.) to a professional filter manufacturer, who can then recommend the most suitable, safe, and reliable product for your needs.
The efficiency of HEPA Filter
The efficiency of currently available high-efficiency filters ranges from 99.9% to 99.999999%, and they can be selected based on specific requirements. The rational selection of filter efficiency and face velocity contributes to comprehensive economic benefits.
For filters made of the same material, higher efficiency typically results in greater resistance and higher cost, while lower efficiency leads to reduced resistance and cost. Altering the air velocity will also affect resistance, efficiency, and the number of filters required, so appropriate selection should be made according to specific conditions.
Service Life of Filters
As dust accumulates on the filter media, the resistance increases. When the resistance reaches an unreasonable level, the filter must be discarded. Sometimes, excessive resistance can cause previously captured dust to become dislodged and re-enter the airflow; when this risk arises, the filter should also be replaced. The resistance of a filter increases with higher airflow rates. By increasing the surface area of the filter media, the relative velocity of air passing through the filter can be reduced, thereby decreasing the resistance.
