250°C – 450°C High-Temperature High Efficiency HEPA Air Filter  

Product Overview

AALfilter’s High-Temperature HEPA Air Filter is designed to provide high-efficiency air filtration in high-temperature environments up to 450°C. Utilizing corrugated aluminum foil separators, this filter ensures structural stability, high airflow, and uniform air distribution even under extreme conditions. Its ultra-thin, high-temperature-resistant fiberglass filter media effectively captures fine particles, making it ideal for industries that require clean air under high heat conditions such as pharmaceuticals, coating lines, ovens, aerospace, and automotive manufacturing.

Key Features

✅ High-Temperature Resistance – Suitable for continuous operation at 250°C, 350°C, and up to 450°C
✅ High Efficiency & Low Resistance – Captures 99.99% of airborne particles down to 0.3µm while maintaining low pressure drop
✅ Corrugated Aluminum Foil Separator – Provides excellent heat resistance, durability, and uniform pleat spacing
✅ Thicker Design (≥150mm) – Increases dust-holding capacity and supports high airflow rates
