After many prototypes and extensive testing, Air Cleaning Blowers, LLC was able to patent the first Air-Cleaning Blower^TM (ACB) as a device that moves and cleans air without the use of any filter media.  Instead of blocking and collecting the debris with filter elements, ACBs use the momentum of the particles in novel ways to separate them from the air and, unlike cyclonic filters, eject them directly.  The benefit from using an ACB is that they blow and clean air without any filter cartridges, sheets, or bags to clog, buy, store, replace or dispose.  Since debris does not accumulate in the units, you can count on steady airflow, air pressure and power consumption.

No filter elements means no filter maintenance! —and, therefore, no deferred maintenance either.
