China Suppliers Factory Galvanized Steel Frame Box Type Activated Carbon Filter with EN 779 Standard
VOC exhaust treatment in spraying, printing, and electronics manufacturing industries (often as a pre-treatment or core treatment unit). Process exhaust purification and deodorization in chemical and pharmaceutical plants. Fume hood exhaust treatment in laboratories.
Oil fume odor purification in large commercial kitchens (requires integration with grease removal devices). Ventilation and deodorization in underground parking garages and sewage treatment stations. Odor control in food processing plants.
Fresh air purification in high-end office buildings, hospitals, museums, and airports to improve Indoor Air Quality (IAQ), removing outdoor ozone, vehicle exhaust, or indoor decoration pollution.
⭐ Special Locations: High-intensity odor control in places like airport smoking rooms, animal housing facilities, and waste transfer stations.
SO₂, NO₂, H₂S, HCL, HF, Etc.
NH₃, Amines, Etc.
- High Efficiency & Broad-Spectrum: Effectively removes various VOCs, odors, acidic/alkaline gases, and some inorganic gases.
- Simple Structure: Easy to install, maintain, and replace.
- Moderate Air Resistance: A well-designed box balances adsorption efficiency with system pressure drop.
- Flexible Customization: Box dimensions, carbon bed thickness, activated carbon type, and fill volume can be customized based on air volume, pollutant concentration, and treatment requirements.
- Cost-Effective: A relatively economical option for treating medium-to-low concentration, high-volume exhaust gases.
📦 Box (Casing): Typically made of carbon steel, stainless steel, or corrosion-resistant PP plastic to ensure structural strength and sealing. Usually a rectangular prism shape with flanges for easy connection to ductwork (inlet and outlet).
🔀 Air Flow Distribution & Support Structure: Front Flow Distribution Screen/Plate ensures air flows evenly through the carbon bed, preventing "channeling" (air taking the path of least resistance) and maximizing the use of all carbon. Support Screen/Plate is located at the bottom of the box or between carbon layers — it prevents fine activated carbon particles from being carried out by the air stream and supports the weight of the carbon bed.
🚪 Access Door/Port: Facilitates the replacement of saturated activated carbon media.
🔬 Carbon Type Selection: Chosen based on target pollutants (e.g., coconut shell carbon, coal-based carbon, impregnated carbon). For example, acid-impregnated carbon is specifically used to treat alkaline gases like ammonia and amines.
