ABSTRACT:
An air filtration apparatus includes a lower intake duct and an upper exhaust duct interconnected by a telescoping vertical pipe section permitting vertical length adjustability of the exhaust duct relative to the intake duct. A blower is mounted in the vertical pipe section to draw air through an intake opening in the forward end of the intake duct, through the vertical pipe section and outwardly through an exhaust opening in the bottom surface of a forward end of the exhaust duct. Particulate filters are mounted in the intake and exhaust openings. A length adjustable upright extending between the intake duct and exhaust duct permits selective adjustment of the height of the exhaust duct over the intake duct. A filter rack on the forward end of the intake duct includes a clamping apparatus which permits various sizes of filters to be inserted in the filter rack.
