    Product Details

    Application Area
    🏭
    Industrial Environmental Protection
    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.
    🏢
    Commercial & Civil Use
    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.
    🌬️
    HVAC Systems & Special Locations
    Fresh air purification in high-end office buildings, hospitals, museums, and airports to improve IAQ — removing outdoor ozone, vehicle exhaust, or indoor decoration pollution. High-intensity odor control in airport smoking rooms, animal housing facilities, and waste transfer stations.
    Filter Media Materials

    We have 3 types of Carbon Activated Media to meet your needs:

    Type A
    VOC and Ozone, Etc.
    Type B
    Acidic Gases
    (SO₂, NO₂, H₂S, HCL, HF, Etc.)
    Type C
    Alkaline Gases
    (NH₃, Amines, Etc.)

    Activated carbon is the core of the filter, and its type and quality directly determine the filtration performance.

    ⭐ Key Features & Advantages
    • 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.
    Core Structure and Components

    🔩 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: Located at the bottom of the box or between carbon layers — 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.

    🛡️ Pre-Filter (Optional but Recommended)
    Sometimes, a primary or medium-efficiency filter is installed upstream of the box to first remove dust and particles from the air stream. This prevents clogging of the activated carbon micro pores and significantly extends its service life.

    Media Types:

    🪨
    Granular Carbon
    Most common, strong adsorption capacity, adjustable packing density.
    🍯
    Honeycomb Carbon (Block Carbon)
    Low-pressure drop, suitable for high air volume applications.
    🧵
    Activated Carbon Fiber Felt/Cloth
    Fast adsorption speed, often used in composite filter elements.
    ⚗️
    Carbon Type Selection
    Chosen based on target pollutants (e.g., coconut shell carbon, coal-based carbon, impregnated carbon). Acid-impregnated carbon is specifically used to treat alkaline gases like ammonia and amines.

    Frequently Asked Questions (FAQ)
    Q What types of pollutants can a box-type activated carbon filter remove?
    Box-type activated carbon filters are effective at removing a wide range of pollutants, including VOCs (volatile organic compounds), odors, acidic gases (such as SO₂, NO₂, H₂S, HCL, HF), alkaline gases (such as NH₃ and amines), ozone, and some inorganic gases. The specific performance depends on the type of activated carbon media selected.
    Q How do I choose the right type of activated carbon media (Type A, B, or C)?
    The selection depends on the target pollutants in your application. Type A is designed for VOCs and ozone. Type B is formulated for acidic gases such as SO₂, NO₂, H₂S, HCL, and HF. Type C is suitable for alkaline gases like ammonia (NH₃) and amines. For mixed pollutant environments, a combination of media types may be recommended.
    Q How often does the activated carbon media need to be replaced?
    The replacement frequency depends on factors such as pollutant concentration, air volume, operating hours, and the type of carbon used. In general, the carbon media should be replaced when adsorption capacity is saturated — indicated by breakthrough of pollutants downstream. Installing a pre-filter upstream can significantly extend the service life of the carbon media by preventing dust clogging of the micropores.
    Q Can the filter dimensions and carbon bed thickness be customized?
    Yes. Box dimensions, carbon bed thickness, activated carbon type, and fill volume can all be customized based on your specific air volume, pollutant concentration, and treatment requirements. Customer-specified sizes are fully supported, as noted in the technical parameters.
    Q What materials are used for the filter casing, and which should I choose?
    The filter casing is typically available in carbon steel, stainless steel, or corrosion-resistant PP plastic. Carbon steel is suitable for general industrial environments. Stainless steel is recommended for corrosive or high-humidity conditions. PP plastic is ideal for highly corrosive chemical or acid/alkali gas environments. The choice depends on your specific operating conditions and budget.
    Q Is a box-type activated carbon filter suitable for high-concentration exhaust gas treatment?
    Box-type activated carbon filters are most cost-effective for treating medium-to-low concentration, high-volume exhaust gases. For high-concentration exhaust streams, activated carbon adsorption is typically used as a pre-treatment or post-treatment unit in combination with other technologies (such as catalytic combustion or plasma treatment) to ensure optimal performance and carbon longevity.
