The CDB8 was designed specifically for Lint-Laden Exhaust from Commercial Clothing Dryers. It can be installed In-line in a straight duct run using the IEK8 Elbow Kit or used as a 90 degree Elbow since the Inlet / Outlet duct connections are on the same center plane. The CDB8 can be powered by many different control options including industry standard Motor Contactors, Solid State Speed Controls and Single Phase VFD's for 10 to 1 modulation. The CDB8 includes Tjernlund Products’ Patented Thermal Cooling System which protects the motor at low operating speeds.
