Custom Size High Temperature Pre Filter 250°C Resistance G4 Efficiency for Furnace Primary Filtration
High-temperature resistant primary filters, also known as high-temperature coarse filters, are engineered for demanding industrial applications requiring superior heat resistance and filtration efficiency.
Manufactured from ultra-fine glass fiber material and formed into a "W" shape through specialized processing, these filters provide large effective filtration area, low initial resistance, and extended service life. Ideal for primary air filtration in high-temperature ovens, hot blast systems, and coating plant applications.
- Thin structure design for space-efficient installation
- High dust holding capacity for reduced maintenance frequency
- Temperature resistance up to 250°C for extreme environments
- Synthetic fiber & fiberglass construction prevents breaking or shedding
- Large effective filter area ensures optimal airflow with minimal resistance
Specifically designed to capture tar, coom, and dust particles from high-temperature dryers and industrial ovens, protecting downstream equipment and maintaining air quality.
