Abstract
An air filtration apparatus for industrial applications is disclosed, which includes a front vertical wall which can be positioned to form one side of a work station. The interior of the housing is divided between an upper dirty air chamber which receives the contaminated air from the work station, and a lower clean air chamber. The dividing wall between the two chambers is in the form of a transverse panel which is inclined with respect to the horizontal, and a plurality of hollow pedestals extend upwardly from the transverse panel. Cartridge type filters are mounted upon the pedestals, with the open ends of the filters facing downwardly and being pressed against the pedestals by hand operated clamps so as to form a seal therebetween. A reverse pulse air cleaning system is also provided, which periodically injects a pulse of air upwardly into the lower open end of each of the filters, so as to periodically clean the collected particulates from the outer surfaces of the filters. The removed particles then drop onto the inclined transverse panel and slide therealong toward to the front vertical wall of the housing, where they may be readily removed.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
