An ultra-high-efficiency gas-phase adsorber called the Vari-Klean provides continuous removal of low-level concentrations of airborne molecular contamination of less than 500 parts per billion, the company says. Fine mesh carbon granules are bonded to a fibrous substrate. Greater than 98.5% of the surface is exposed to contaminated air for maximum gas adsorbing efficiency and capacity, the company says.
