Disposable, brick-like filters

OCT. 22–ARLINGTON HEIGHTS, Ill.–International Air Filtration has developed patented disposable bonded “brick” gas filters, which are constructed of a bonded media combining activated carbon and proprietary oxidizers.

The process entails binding the medias into a monolithic structure with a polymeric binder, while maintaining a very high level of open-pore structure to provide better oxidation and adsorption of gases and odors.

The oxidizers remove lower molecular-weight gases, and the carbon adsorbs higher molecular-weight gases.
This unique combination captures odors and gases with efficiencies of up to 90 percent by weight.

With IAF brick gas filters, there is no dusting or mess; when the filter is spent, just remove it and throw it away. These filters are available in a variety of sizes.

IAF brick gas filters can do everything functionally that the traditional loose-fill carbon/potassium perman-ganate filters can, but with distinct advantages over the granular medias, including:

1. Higher efficiency due to the elimination of settling and a higher mass to volume ratio -less void space between particles. (Settling and particle attrition permit bypass of thecontaminants.)
2. Less dusting due to vibration.
3. Brick filter panels are constructed by a patented process that is simpler, less time-consuming and less costly than loose-fill carbon filters.
4. Brick filter panels can be impregnated with the right chemical additive to solve virtually any particular gas filtration problem.
