 Phoenix Guardian HEPA System - True 1400 CFM Air Scrubber
The Phoenix Guardian HEPA System was the first portable air scrubbing device designed exclusively for the restoration industry. The Guardian can perform several critical air quality remediation functions simultaneously. The Guardian HEPA System captures virtually all removable airborne particles. The optional 4-stage absorption filter contains a blend of activated carbon and potassium permanganate to remove airborne odors and chemicals. The true 1400 cfm capacity of the Phoenix Guardian HEPA System will clean one air change of a 12 x 14 foot room in less than a minute. In order to be effective, an air scrubber should be able to perform a minimum of four air changes per hour. Therefore, a single Guardian can be expected to control up to 21,000 cubic feet. The Guardian's high airflow and multiple ducting options allow for the combination of negative or positive air flow control of an area and containment air scrubbing at the same time. This provides the unique ability to continually filter the indoor air and depressurize the damaged site to prevent the spread of contamination simultaneously. The Guardian's intake will accept either 18" flexduct or 12" flex-duct with the included adapter, to pressurize areas for protection from contamination or to draw contaminated air from areas that are difficult to access or too small to accommodate an air scrubbing device. Every Guardian HEPA System comes with one 14" lay-flat duct ring, for 100% negative air operation, and two 10" lay-flat duct rings for a combination of negative air, air scrubbing or positive airflow.
