ABSTRACT:
A U-loop air handling apparatus adapted to receive air from a surrounding environment for conditioning and channeling thereof to return ducts. The conditioning includes cooling and filtration thereof such as to be specifically usable in high technology areas requiring extremely clean working conditions. The apparatus includes a fan operatively positioned between an intake section and an output section. The intake section includes a reducing section for receiving air and passing this air through a pre-filter and a cooling coil. Condensation is removed at the cooling coil and a cross sectional area of the channel of air travel is narrowed to a smaller diameter by the reducing section. A fan box receives the conditioned air from the reducing section where it is carried through an inlet box and bell member into the fan. The fan powers the air outwardly into an acoustical box which channels the air parallel and in an opposite direction with respect to the direction of movement of the air within the intake section. The acoustical box carries the air through a damper box to prevent back flow and outwardly through a transition box to return to the environment. The various air carrying members are internally lined with acoustical insulation to minimize transmission of sound and vibration outwardly into the environment resulting from air movement or from the operation of the fan. Also the fan itself is separated vibrationally and acoustically from a portion of the intake section and a portion of the output section by flexible connecting means of rubber-like material, preferably neoprene. Further isolation is provided by independent support means being provided for the fan box and for the reducing section and for the acoustical box.
