D-Mark Adsorball bulk carbon V-bank honeycomb air filters provide gas-phase odor control for commercial and industrial HVAC systems with heavier concentrations of unwanted gases. The design allows a high volume of activated carbon to be installed in new or existing HVAC systems, with gas-adsorbing granules selected for the target contaminants.

Carbon granules are suspended in a honeycomb matrix within a double-walled, high-strength plastic frame for industrial applications. Moisture-resistant adhesive provides a continuous seal and pack strength. The specification identifies applications involving food and cooking odors, hospital odors, animal odors, offices and sports arenas.

The standard Adsorball carbon configuration is filled with 100% 6 x 12 mesh, industrial-grade, 60 CTC high-activity carbon for organic and specific molecular gas-phase control.
