24-Inch Aluminum Exhaust Fan
The Dayton 10D990 is a 24-inch industrial direct-drive exhaust fan built for commercial or agricultural ventilation. Its aluminum blades and galvanized steel frame suit continuous airflow duties in barns, warehouses or large workshops. The unit operates on dual 115/230V supply and delivers 654 cfm at zero static pressure.
Replacing Belt-Drive Units
Direct-drive construction removes belts, pulleys and tension adjustments that wear on older belt-driven fans. The jump is worth it when maintenance access is limited or when a simpler, quieter drivetrain cuts service intervals. No dehumidistat is included, so humidity-triggered automation must be added separately.
Build Integration
A 24 1/2-inch duct diameter matches the blade sweep for straight-through mounting in wall or shutter openings. Galvanized frame flanges bolt to standard curb or wall sleeves without adaptors. The 29-sone rating means the fan is audible in occupied spaces, so locate it away from quiet zones or add external silencing.

Questions about this item
What duct diameter does the 24 in aluminum exhaust fan require?
The fan is designed for a 24 1/2 in duct diameter to match the blade size and frame opening.
How is the Dayton 10D990 wired for 115V versus 230V operation?
The motor is dual-voltage; follow the wiring diagram on the nameplate to configure the leads for either 115V or 230V supply.
When should the aluminum blades on this direct-drive fan be inspected or replaced?
Inspect blades annually for fatigue cracks or corrosion; replace if any blade shows deformation or material loss that could unbalance the rotor.
