CFV 4×8 Coconut Shell Granular Carbon – Low Pressure Drop HVAC Odor Control

Key Features

• High CTC adsorption value (>50%)

  Offers higher loading capacity for benzene, esters and common VOCs, extending filter bed service life and reducing scheduled changeout frequency.

• Standard 4×8 mesh sizing

  Matches most commercial HVAC filter box dimensions for drop-in replacement, eliminating the need for system redesign or equipment upgrades.

• High-hardness coconut shell base (>95% hardness)

  Produces very little dust under continuous airflow scouring, preventing dust buildup on downstream coils and ductwork.

• Uniform particle gradation

  Creates even fill with no dead zones in the filter bed, ensuring uniform airflow distribution and avoiding premature breakthrough in localized areas.

• Thermally regenerable for repeated use

  Reduces long-term operational costs, making it well suited for continuously running ventilation systems.

Applications

• HVAC System Odor & VOC Saturation: Commercial buildings face persistent renovation fumes, occupancy odors and ambient VOCs that standard HVAC filters cannot address. CFV 4×8's high CTC coconut shell structure adsorbs these gas-phase contaminants at typical ventilation face velocities, upgrading air quality without system redesign.

• Industrial VOC Exhaust Pre-Treatment: High-concentration exhaust streams from manufacturing processes can overwhelm downstream polishing carbon. CFV 4×8 serves as a front-end buffer layer, capturing large-molecule and high-boiling-point components to protect core recovery media.

• Wastewater Treatment Plant Covered Deodorization: Biofilters treat bulk odors but often release residual sulfide compounds. CFV 4×8 acts as a polishing stage after biological treatment, removing residual H₂S and organic sulfides before atmospheric discharge.

• Chemical Storage Area Ventilation: Tank breather valves and drum storage release low-concentration organic vapors. CFV 4×8's gas-phase optimized pore structure captures these fugitive emissions to maintain facility air quality.

Technical Advantages

• High CTC adsorption value provides higher loading capacity for benzene, esters and common VOCs, extending filter bed service life.

• Standard 4×8 mesh sizing matches most commercial HVAC filter boxes for direct drop-in replacement without equipment modification.

• High-hardness coconut shell base produces minimal dust under continuous airflow, preventing downstream coil and ductwork contamination.

• Thermally regenerable structure reduces long-term operational costs for continuously running ventilation systems.

FAQ

Q: Which is better for shopping mall HVAC, CFV 4×8 or PLC-370 pelletized carbon?

A: Choose CFV 4×8 if your existing filter housing is designed for granular fill, allowing direct drop-in replacement. For new installations targeting the lowest possible pressure drop, PLC-370 pelletized carbon is a strong alternative. Both deliver similar results for typical mall odor control.

Q: How often should CFV 4×8 be replaced in office buildings?

A: At typical indoor VOC levels, expected service life is 12–24 months. Near industrial sources or restaurant exhaust, shorten to 6–12 months. Outlet odor sampling is the most reliable replacement indicator.

Q: Can CFV 4×8 be used alone for high-concentration industrial exhaust?

A: We do not recommend it as a standalone solution for high-concentration streams. It works well as an intermediate buffer layer paired with upstream scrubbers and downstream P-100 high-iodine pelletized carbon for polishing.
