The bracket comprises upper and lower sections which are permanently connected when in assembled relation. The rear of the casing has a pair of channel elements and therebetween a wedge lock element, the bracket having a plurality of laterally opposite pairs of slide sections with bottom stops, said slide sections being slidably interengageable with said pair of channel elements, the casing being held by said stops in the selected operative position. The bracket has a plurality of vertically aligned apertured portions each being positioned for locking engagement with said wedge lock element when the corresponding pair of slide sections is in the said selected operative position, whereby the casing is held locked on said bracket. An air pipe is supported by said bracket and is adapted to extend through a selected one of the bracket''s apertured portions for operative connection to the filter casing.
