Nu-Calgon 4900-50 NuShield-CI is a bi-polar ionization generator designed to improve indoor air quality. It fits light commercial systems with a capacity of up to twelve tons, or forty-eight hundred cubic feet per minute. This device does not need replacement parts for several years, unlike UV lights and other ionizer technologies.
This generator enhances air quality by emitting positive and negative ions. As air flows past it, these ions reduce bacteria, viruses, smoke, and odors in the environment.
