250 Degree High Temperature HEPA filter

Introduction:

250℃ high-temperature resistant filter’s terminal purification system is engineered for continuous high-temperature industrial environments, maintaining particle filtration efficiency and structural integrity at extreme temperatures up to 250°C while delivering dust-free hot air for critical processes. Featuring a stainless steel frame, high-temperature resistant aluminum partitions, and silicone seals, it achieves H13/H14 filtration efficiency (≥99.95% for 0.3μm particles) and ensures reliable operation without leakage under extreme heat conditions.

Common Model:

Process design features:

1.    Material system optimized for high-temperature applications:

Filter material: High-temperature resistant glass fiber filter paper, which does not become brittle or pulverized under prolonged high temperature.

Structure: The design with separator provides the most reliable rigid support for the filter material, effectively resists thermal stress and prevents the collapse of filter folds, which is difficult to guarantee in the mini pleat design at 250℃.

Sealing: Utilizes silicone material resistant to temperatures above 250°C, ensuring zero leakage.    Conventional adhesives crack and evaporate at high temperatures, causing leaks and contamination.

2.    Core Process — Preheating Treatment:

Each 250℃ filter undergoes a rigorous stepwise heating pretreatment (progressively reaching 100℃,150℃,200℃ and 250℃ with constant temperature) before leaving the factory. This process thoroughly releases internal material stresses and volatile substances, ensuring High-Temperature High-Efficiency Filter is ready-to-use and safe.

3.    Rigorous quality control and testing:

Perform 'per-unit efficiency and leak detection' (e.g., MPPS method) to ensure 100% compliance with efficiency and sealing standards for each filter unit

Applicable places and fields of application:

1.   Pharmaceutical and Bioengineering: For terminal air supply in dry heat sterilizers, tunnel ovens, and sterile production facilities.  250℃ High temp resistant filters can withstand high-temperature sterilization cycles without releasing any chemicals.

2.   New energy (lithium battery) manufacturing: Used in critical processes like electrode material drying and coating baking. 250 Celsius Degree High Temp HEPA Filter efficiently traps dust at high temperatures, featuring filter materials with low metal ion release and stainless steel frames to prevent contamination of battery components, ensuring battery safety and performance.

3.   Industrial painting and surface treatment: Used in automotive and furniture baking booths and drying tunnels. It withstands high-temperature drying and efficiently filters airborne particles to ensure paint quality.

4.   Chemical and food processing: Suitable for drying chemical raw materials, baking lines, cleaning machines, and other hot air systems. The products are heat-resistant and corrosion-resistant, meeting the hygiene standards of the food industry.
