Meta-Aramid Pleated Felt Filter Media for High-Temperature Cartridge Filters

Meta-Aramid Pleated Felt Filter Media for High-Temperature Cartridge Filters

Meta-aramid pleated needle felt filter media engineered for high-temperature cartridge filtration, offering thermal stability, high airflow capacity, and reliable antistatic performance.

Product Overview

Meta-aramid pleated felt filter media is designed for high-temperature cartridge dust collection systems that require enhanced thermal resistance, dimensional stability, and reliable performance under heavy dust loading.

Manufactured from high-quality meta-aramid (aromatic polyamide) short-fiber needle felt, this media provides excellent heat resistance and mechanical stability, making it suitable for continuous operation in demanding industrial environments.

Through high-temperature stiffening and setting treatment, the needle felt achieves improved rigidity and dimensional stability. This enables consistent pleat forming and long-term structural integrity during pleated filter cartridge manufacturing and operation.

The media is widely applied in cement plants, steel production, metallurgical processes, and other high-dust, high-temperature industries, where higher airflow capacity and antistatic performance are required.

｜Key Advantages

｜Higher Continuous Temperature Capability

Designed for continuous operation up to 200 °C, with short-term temperature peaks up to 220 °C, meeting the requirements of high-temperature cartridge filtration systems.

｜High Air Permeability

Provides higher airflow capacity than PPS-based media, making it suitable for applications requiring lower pressure drop and stable system operation.

｜Antistatic Performance of Meta-Aramid Pleated Felt Filter Media

Carbon impregnation treatment effectively reduces electrostatic charge accumulation in dry, high-dust environments, supporting safe and stable long-term operation.

｜Thermal and Mechanical Stability

The meta-aramid fiber structure maintains strength and dimensional stability under prolonged exposure to elevated temperatures and repeated cleaning cycles.

｜Optimized for Cartridge Filter Manufacturing

Controlled thickness and stiffness support reliable pleating, cartridge assembly, and long service life in industrial filtration systems.
