Product Overview
CFV 4×8 is engineered for the unique demands of vapor-phase applications where gas contact time is limited and pressure drop must be minimized. The 4×8 mesh size (approximately 2.36–4.75mm) provides an open bed structure that allows high face velocities without excessive backpressure—critical for large-scale air handling systems and industrial exhaust treatment.
While finer carbons offer more surface area per unit volume, they create flow resistance that can cripple blower performance. CFV 4×8 sacrifices some volumetric capacity for superior hydraulic performance, making it the practical choice for:
Key Application Areas
- Industrial HVAC systems — VOC and odor control in manufacturing facilities
- Soil vapor extraction (SVE) systems — petroleum hydrocarbon removal from contaminated sites
- Tank vent emissions control — compliance with VOC emission regulations
- Solvent recovery operations — capture and recycle of valuable organic solvents
- Biogas and landfill gas treatment — H2S and siloxane removal

Design Advantages
- Low Pressure Drop: The coarse particle size minimizes flow resistance, reducing fan energy consumption and allowing smaller blower specifications
- Reduced Channeling: Uniform particle size distribution promotes even gas distribution across the bed cross-section
- Easy Handling: Larger granules are less prone to dusting during filling and emptying operations, improving workplace safety
- Deep Bed Compatible: Ideal for deep-bed designs where contact time compensates for the lower surface-area-to-volume ratio
