Abstract

A sound-baffling arrangement for use in conjunction with an air-handling unit. One or more sound baffle columns are mounted for rolling or sliding movement within the interior of the air handling unit housing. Each baffle column may be selectively moved between a use position proximate to the fan assemblies, and a non-use position more distal from the fan assemblies. The movable sound baffles permit the air-handling unit to be fabricated to fit within a smaller housing, and thus to have a smaller, more economical footprint.

Claims (8)

1. An air-handling unit, comprising:

a housing;

at least one fan assembly for moving air through the housing in a direction toward a downstream feature;

at least one guidance track on a floor of the housing;

at least one baffle column upon the track, and selectively movable, along the track substantially parallel to the direction of moving air, between a use position proximate to the fan assembly and a non-use position more distal from the fan assembly.

2. An apparatus according to claim 1 wherein the at least one baffle column comprises a plurality of baffle columns disposed substantially mutually parallel and substantially parallel to the direction of the moving air.

3. An apparatus according to claim 1 wherein the at least one baffle column comprises a sound-attenuating plenum.

4. An apparatus according to claim 1 wherein the at least one baffle column comprises an air filter.
