TDC Tubeaxial Direct Drive Duct Fan
American CoolAir Type T duct tubeaxial Model TDC Fans are high performance, axial flow fan designed for duct connected applications, suited to meet your ducted fan needs for high pressure and air volume both economically and efficiently. Suggested for commercial and industrial uses such as make-up air systems, booster fans, return air fans or to exhaust contaminated or high temperature air, Type TDC fans are available in a large selection of CFMs (from 1,500 to 76,000 CFM) and operate efficiently against static pressures up to 2.5 inches.
Blade Assembly: The propeller assembly is connected directly to the motor shaft. There are no fan bearings or belts that require maintenance. TDC models have from 3 to 6 cast aluminum airfoil blades that are securely attached to a heavy cast aluminum hub. Blade pitch is set for catalog performance. Type TDC fans incorporate specifically engineered airfoil sections and hub sizes for optimum efficiency and physical strength.
Construction: The fan housing and motor supports are made of heavy gauge steel plate for maximum strength and durability. Painted parts are coated with a baked-on epoxy to provide a protective coating rated excellent for hardness, impact resistance, adhesion and chemical resistance. The fan unit is mounted within the housing with flanged ends to form a complete fan-duct section. All blade assemblies are dynamically balanced. Parts requiring painting are processed through the advanced American Coolair five-stage pretreatment system prior to the application of any coatings to ensure maximum finish adhesion. These parts use a thermosetting epoxy powder paint with an average thickness of 3 mils and baked at 400 degrees Fahrenheit to a smooth, hard, continuous finish. The motor is inside the air stream. External grease fittings for relubrication of motor bearings are optional accessory.
Motors Totally enclosed motors are standard for all models. Several alternatives are available to fit your specific needs, such as explosion proof motors, two-speed motors, energy efficient motors and severe duty motors. only nationally recognized brand motors with nationwide service facilities are used.
Spark Resistant Construction: For hazardous locations, any Type T fan can be ordered with an explosion-proof motor. Motors only qualify for Class I Group D and Class II Groups F & G hazards. Special non-ferous construction blade assembly completes requirements for spark resistant construction.
Accessories Access Panel, Mounting Feet, Mount Brackets and Mount Lugs, Inlet Bell with Guard, Inlet/Outlet Guards, Companion Flanges, Vibration Isolators RIS & SIS, Prewired Motor, Flexible Connections and Transition Pieces.
Listings: UL listings and Certified ratings authorized by AMCA (Air Movement and Control Association, Inc.) for air performance are available on all Type TDC Fans.
