Application
Model TXB belt drive fans are roof mounted centrifugal upblast exhausters rated from 250 to 35,000 CFM with static pressure capabilities to 3-1/4 inches. Breidert offers the widest horsepower and CFM selection in the industry. All fans are factory test run for quality assurance. Check our Quickship Program for your rapid delivery requirements.
The TXB was designed with serviceability in mind. The motor compartment can be serviced through the removable top, or the motor housing can be removed by loosening four nuts. Breidert’s optional “Grease Grabber” is an inexpensive and easy solution to grease containment. The Grease Grabber media allows water to drain away while grease is contained.
Isolation of motor and drive components from the airstream and the high velocity vertical air discharge make the Model TXB ideally suited for the removal of dirty contaminated and/or high temperature air from processes and buildings. Typical applications include restaurant hoods and similar kitchen exhaust ventilation, fume and smoke removal, laboratory fume hood exhaust and chemical process exhaust.
All TXB fans are designed and manufactured for high performance and long life. Breidert covers the TXB with a 5 year fan warranty and a 1 year motor warranty. TXB-UL762 units have a 1 year fan and motor warranty. Heavy-gauge materials are used throughout the TXB. The spun inlet and shroud design provide excellent air moving efficiencies. The motor brackets are heavy-gauge steel, and isolated from the unit to eliminate unwanted vibration and noise transmission. For companion direct drive upblast fans, see the Model TXD with it's complementing design. There is no finer centrifugal upblast made period.Construction/Specification Checklist
