AmerSorb™ BP Better Air is Our Business ® • 60% CTC activity carbon • High first-pass removal efficiency and low resistance to airflow • No carbon dusting — no settling • Easy disposal • Individually sealed in cellophane bag for easy handling • Available in various thicknesses Disposable, High Activity Carbon Bonded Panels AmerSorb™ BP disposable carbon bonded panel filters are a direct replacement for 1" panels used in most manufacturers' side and front access housings. An economical alternative to refillable trays used in granular media housings, AmerSorb BP panels are easier to handle and reduce maintenance costs. Patented Bonding Process The patented process uses a polymeric substance to bind activated carbon into a rigid, uniform structure characterized by open pore structure. This bonding process is unique because adsorption properties of the base activated carbon remain virtually unchanged. Conventional bonding methods may corrupt surface area and pore size distribution. Since the adsorptive capacity of the activated carbon is preserved, the need for post-binding activation is eliminated. Higher Efficiency AmerSorb BP carbon bonded panel filters are constructed with 0.25 oz. high-loft, non-woven polyester front and back for protection during shipment and offer particulate removal capabilities as well. Structurally designed to prevent bypass of contaminated air, the carbon is “locked” in place and will not settle, as often occurs in loose-fill trays and honeycomb carbon filters. More Carbon AmerSorb BP bonded carbon panel filters contain approximately 5% more carbon by weight than a comparable size loose-fill panel filter. Since a supporting enclosure is not required, there is additional space for carbon content. Reduced Maintenance Disposable filters eliminate many of the maintenance costs associated with refillable carbon panels. Disposable carbon bonded panels are easy to install and cleaner to handle. No extra freight, handling, or clean up is required. AmerSorb BP high activity carbon granules
