Activated Carbon Filters
Activated carbon filters remove gases, vapours and odours — the fraction a particle filter lets through. Whalesens builds them in four structures so the same chemistry can be fitted to different plenums: flat panel, pleated panel, pocket and V-bank, plus a box-type chemical filter for ducted chemical duty.
The carbon itself comes in several forms — carbon filter cotton, carbon-sandwiched non-woven fabric, activated carbon fibre felt, and granular, spherical or alumina media in the deeper V-bank and box constructions. Matching the form to the gas load is what decides how long the filter lasts, so tell us the contaminant and its concentration rather than only the frame size.
Activated Carbon Filters range

How it compares
Carbon vs a particle filter
A particle filter captures dust; a carbon filter captures molecules. Neither replaces the other, and the order matters: put the particle stage first, because dust blinds carbon and spends its capacity on the wrong problem. Most installations run a pre-filter, a medium filter and the carbon stage in series.
Carbon cotton vs granular carbon
Carbon cotton is thin, light and low resistance, which suits light odour duty in a flat panel where depth is limited. Granular and spherical carbon in a V-bank or box filter gives a deeper bed and a longer residence time, so it holds far more gas before breakthrough — that is the difference between an odour panel and a chemical filter.
Panel, pocket or V-bank
A flat panel is the cheapest way to cover a face and is used for light odour. A pocket adds media area at low face velocity. A V-bank packs the largest media area into a 292 mm depth and is the usual choice where gas capacity, not particle efficiency, is the limiting factor.
Where it is used
Chemical and VOC control
Process and workplace air in chemical plants, printing works and coating lines, where odour and solvent vapour have to be removed before the air is returned or exhausted.
Chemical VOC case →Data centres and computer rooms
Corrosion control for server halls, where a carbon stage removes the gases that attack copper and silver contacts.
Data centre carbon case →Museums and cultural institutions
Showcase and gallery air, where the requirement is to remove pollutants without introducing a filter that will itself off-gas.
Museum filtration case →Coating and oven exhaust
Odour abatement on curing ovens and coating lines, normally downstream of a paint arrestor and a medium particle stage.
