This pleated-media carbon filter combines high gas-phase adsorbency with minimal dusting characteristics, the company says. The Riga-Carb™/PH rigid filter is suitable for IAQ applications where high adsorbency is required, and space and pressure drop limitations exist, says the manufacturer. Examples include commercial and institutional buildings, control rooms and towers, and chemical and VOC-contaminated environments. The filter uses a general-purpose carbon suspended in a fibrous media, using a patented technology that yields maximum adsorbency.
