This brochure provides an overview of the most commonly used activated carbon filters, predominantly in HVAC systems in museums and galleries to remove SO2 and NOx that cause serious damage to exhibits; kitchen extract systems to remove odours; and the printing industry. Two specialist products are featured: one for the removal of odours arising from liquids and one for water treatment.Activated Carbon Filters : How they workActivated carbon is produced by heating coal or coconut-shell to a temperature of 800OC – 1000OC in an atmosphere of steam to provide the micro-pore structure with an extremely high internal surface area within each granule. The carbon surface then attracts contaminant molecules, which are then held firm by Van der Vaal’s forces. This process of physisorption means that many different compounds can be adsorbed onto the carbon.Activated Carbon Filters: Selection & OperationActivated carbon comes in two forms: base carbon and impregnated carbons. While base carbons are suitable for most applications, impregnation will enhance its ability with respect to certain types of gaseous contaminant. Selection therefore requires notification of the types of contaminant to be removed, along with details on air flow and filter measurements to determine the most appropriate format. A range of scrims and pre-filters are also available to protect the activated carbon from particulate contaminants.Pre-FiltersTo protect the activated carbon from particulate contaminants a range of pre-filters are available including scrims, pads and pleated panels.

Isotherms are also available to show performance levels of carbon types against specific chemical contaminants.Activated Carbon Filters – product guideActicel Carbon Unit? Available as bonded carbon or loose fill filters? Zintec steel case? Air bypass avoided by sealing filters into the case? Standard and non-standard sizes available? Supplied with or without headers as requiredDeveloped for use in areas where high level odours and gases need to be removed. The carbon panels are arrayed in a ‘V’ formation, sealed into a robust ‘base frame’. Units must be installed with panels in the horizontal plane.Acticel Carbon Unit Technical Data Sheet ACF/TDS305Multi-Pack Filter Cartridge? Combination filter to remove odours and particulates? Lighter construction? Cells are replaceable – main housing can be re-usedSituations can arise where there is a low level of odour but sufficient to cause discomfort to building occupants, and the need for particulate filtration remains. The Multi-Pack provides the most cost-effective solution as a first stage in ascertaining the seriousness of the odour problem and before engaging in expensive system modifications.Multi-Pack Cartridge Technical Data Sheet ACF/301Loose Fill Carbon Panel Filters? Lower pressure loss than bonded carbon? Lighter constructionLoose fill carbon panels provided the advantage of being lighter in construction and lower in pressure loss compared with bonded carbon filters. A range of loose fill carbon filters are available, using base or impregnated carbon, in a variety of sizes. Loose Fill Panel Filters Technical Data Sheet ACF/TDS303Bonded Carbon Panel Filters Technical Data Sheet ACF/TDS304Bonded Carbon Panel FiltersSome situations continue to favour the supply of a bonded carbon panel. These may be supplied as a single panel or installed into multi-vee banks to suit airflow. The product is ideally suited for inclusion in air handling units where the application requires removal of specific gases, such as SO2 and NOx in museum and gallery applications, or other general odour removal.Activated Carbon Filters – product guideContact Active Carbon Filters Ltd for full specifications on all items featured.ACF/CarbonGen/Issue 1Actisys Side Access Panel Filter Housings? 36 sizes of housing available? Capacity to handle a wide range of airflows? Tracking design allows easy filter installation? Weatherproof construction? Two access doorsHousings as well as filters can be supplied.Actisys Access Housings Technical Data Sheet ACF/TDS451Combination Filters Technical Data Sheet ACF/TDS501Combination FiltersFilters combining activated carbon and a particulate filter are used in fume extraction units designed for laser cutting, soldering, brazing, welding or engraving of metals and plastics, and in laser printing systems. The carbon bed and HEPA filter are bonded into the filter case. The case may be constructed from zintec, stainless steel, aluminium, or polypropylene depending on preference and/or application.
