BETEC CAD manufactures carbon filters for use in air conditioning and ventilation systems for the removal of odorous gases and harmful vapors from existing conditioned air zone. These carbon filters are enclosed in a strong galvanized steel frame casing with internal perforated galvanized steel splitters for mounting filter cells. The casing can be supplied to match specific dimensions. The filter media is impregnated moisture-resistant board with activated carbon cells in a securely fixed wedge shaped arrangement. Activated carbon filter material is treated with an anti-microbial treatment to inhibit the growth of germs,bacteria, and mold fungi on the filter. Neoprene / Silicon seals are used for sealing the carbon cells, which prevents air bypass in the filter rack.
