Our custom granular activated carbon air filters are designed for cleanroom HVAC systems, air handling units (AHUs), industrial ventilation, and odor and gas-phase air filtration applications.​

The filter is constructed with a durable aluminum alloy frame and a deep bed of coconut shell granular activated carbon, securely retained between protective wire mesh and pre-filter layers.​

This structure provides a high carbon filling capacity while maintaining a stable and practical panel filter design for installation in HVAC and air purification systems.​

As a direct activated carbon air filter manufacturer in China, we provide OEM and ODM customization based on customer drawings, filter dimensions, airflow requirements, carbon specifications, and application conditions.

2. High-Loading Coconut Shell Activated Carbon

The filter is filled with granular coconut shell activated carbon to provide a high carbon loading capacity for gas-phase air filtration. The activated carbon is designed to help adsorb odors, VOCs, and selected gaseous contaminants from air streams.

3. Secure Multi-Layer Filter Structure

The filter features a reliable layered construction of metal wire mesh + pre-filter + activated carbon granules + pre-filter + metal wire mesh. This structure securely retains the carbon particles while providing a stable and durable filter assembly for continuous air filtration.

4. Custom Designed for Cleanroom & HVAC Systems

Available in custom dimensions, thicknesses, carbon filling weights, particle sizes, pre-filter materials, and wire mesh specifications. Suitable for cleanroom HVAC, AHU, industrial ventilation, laboratories, pharmaceutical facilities, electronics manufacturing, and other gas-phase filtration applications.

5. Factory Direct OEM & ODM Manufacturing

As an experienced activated carbon air filter manufacturer in China, we provide direct factory OEM and ODM services. Customers can send drawings, samples, dimensions, or technical requirements for customized development, sample production, bulk manufacturing, inspection, and export packaging.
