The Air Cleaning BlowerTM (ACB) was developed specifically to remove dust, pollen, flying bugs, and other particles, including CBRNE, from the air in dusty and harsh environments while eliminating the need for filter maintenance due to clogging filters. After removing most kinds of desert and military dusts, without using any filter elements or media, the ACBs blow clean air into your tent, emergency vehicle, modular building or other temporary medical facility.
The Air Cleaning Blowers work by pulling that dirty air into their housings like any other fan would. The impeller and housing are specially designed to use the momentum of the contaminants to separate them from the air (or almost any other gas) and fling them toward the outside of the housing and eject them, most commonly back into the atmosphere from where they came. The clean air then continues toward the application for ventilation or pressurization. ACBs accomplish all this without any type of filter elements, sheets, cartridges, bags or other media to maintain.
Media filters remove contaminants from air and other gases by stopping and collecting them. As a result, they all clog and need maintenance and, sooner or later, replacement. In addition, as they clog, media filters and air purifiers increasingly impede the flow of air. When they do, the blower has to work harder and consume more electricity or other power to maintain the same airflow and air pressure at the application. In contrast, because they do not trap debris, ACBs do not clog. Without clogging, the filter maintenance is almost eliminated, and, consequently, so is deferred maintenance. Perhaps more important, particularly to designers of the systems, when ACBs supply the air moving and air cleaning, they eliminate the fluctuations in airflow, air pressure and power consumption, which makes it much easier to predict and calculate the air-systems’ performances, and therefore, to design optimal systems.
