The DATVTL T-piece damper is an air distribution units which
can replace two separate ventilation dampers. The easy adjustment
control can divert the air flow to either of the two 90°-spaced legs,
with the other leg automatically closed.
The damper can also be used for supplying air via either of the two legs
from an external air supply valve, a ground-coupled heat exchanger, or a
fireplace hot air hood. All damper sizes come with the KIT-DS-H damper
mechanism control handle for easier operation. The ends of the damper
are provided with EPDM gaskets to ensure air tightness class D.
