Tubeaxial models TXD and TXB, direct and belt drive axial fans, are designed for use in low to medium pressure ducted applications. They are generally used for removing contaminated air or hot air found in industrial applications. They can also be used to supply air through duct work for cooling or pressurizing interior spaces. Tubeaxial fans are very versatile and compact units that move large volumes of air in duct systems having relatively low pressure losses.
