Belt Drive Tubeaxial In-line Duct Fan



The Tubeaxial line offers the widest range of sizes, horsepower, and performance in the industry. TDB’s are high capacity belt drive tubeaxial fans rated from 900 to 75,490 CFM, with static pressure capability up to 1-1/2″. They are used to exhaust air from or supply air to commercial and industrial applications, such as general building ventilation, enclosed garages, paint spray booths, heat and smoke ventilation systems and other applications where the air is moved through a duct system against moderate static pressure.

Belt drive TDB’s are especially suited to handle fumes, vapors, steam, dust, smoke and contaminated or heated air to 200°F. They are available in larger, higher capacity sizes and offer ease in adjustment of fan performance by reducing the fan RPM with adjustable motor sheaves (Optional on 7-1/2″ HP and larger). Total access to the bearings and shaft is possible with the TDB’s unique removable cover.
