Application Scenarios and Selection Criteria for High-Temperature Filters

High-temperature filters are filtration units designed for high-temperature clean environments, suitable for diffusion furnaces, high-temperature tunnel kilns, and specialized process workshops.

I. Temperature Grade Classification

1. Temperature Resistance 200°C: Suitable for general high-temperature environments 2. Temperature Resistance 250°C: Ideal for drying equipment and heat treatment workshops 3. Temperature Resistance 300°C: Designed for diffusion furnaces and sintering furnaces 4. Temperature Resistance 350°C: Built for specialized high-temperature processes

II. Structural Features

1. Filter Media: Special high-temperature resistant fiberglass 2. Frame: Stainless steel or galvanized steel sheet 3. Seal: Metal seal or high-temperature silicone 4. Separator: High-temperature aluminum foil

3. Selection Criteria

1. Determine the maximum operating temperature and duration 2. Account for temperature fluctuation ranges 3. Assess dust properties and concentration 4. Calculate required airflow and filtration area 5. Select appropriate installation method

4. Application Cases

- Semiconductor diffusion furnace: withstands 350°C, ULPA filtration - Pharmaceutical drying tunnel: withstands 250°C, HEPA filtration - Food baking line: withstands 200°C, HEPA filtration
