VariSorb XL filters consist of filter elements assembled in a V-bank configuration, in high-impact, polystyrene (HIPS) cell sides. The header and cell sides provide a sturdy construction that resists damage during shipping, handling, and operation. Constructed of plastic, the VariSorb XL filter is fully incinerable. The pleated filter elements provide a high media area and low resistance.


The VariSorb XL filter features a pleated media comprised of very high-activity carbon particles bonded into a matrix of mini-carbon granulate, embedded between two non-woven synthetic layers. The very small carbon granules, unlike traditional granular bed chemical filters, provide a granular microstructure that ensures a much higher effective area per pound of media, resulting in a high spontaneity of adsorption. Combined with the dense packing of the microstructure, this creates a tortuous path for the contaminant, resulting in a high yield for the filter. The fiber matrix maximizes the exposure of the sorbent to the gas, while securely bonding it within the media. Dusting is nearly eliminated, and pressure drop is minimized.
