The CTA air handling unit is among the most technologically advanced. Available in numerous versions to meet a wide range of needs.
The structure of sheet metal panels bolted together allows the possibility of creating a double wall with sound-insulating and sound-absorbing material. Fastening the panels by bolts is more reliable than by screws, giving the structure high rigidity and at the same time easy disassembly. The control dampers are opposed-movement flaps constructed of sheet steel, the pivots of which are housed on the vertical segments of the frame. The dampers can be manual type or equipped with servo control.
