48-Inch Agricultural Exhaust Blower

The Dayton 7DZ45 is a belt-drive propeller fan built for agricultural ventilation. It moves 19,608 CFM at zero static pressure with a 21.6 CFM per watt efficiency rating. The 1 HP motor runs at 1725 RPM on single-phase 115/230 V power. Totally enclosed air-over construction protects the motor in dusty or humid environments.

Suits High-Volume Barn Ventilation

This unit fits producers who need large-volume air exchange through a 48-inch propeller. Wall-mount design requires a 52-7/8 inch square opening. Buyers needing a smaller footprint, direct-drive simplicity, or variable-speed control should look at other models.

19,608 CFM at Zero Static Pressure

The airflow rating at 0.000 inches static pressure determines whether this blower can meet the barn’s air-exchange target. Motor full-load amps are 9.0 at 115 V and 4.5 at 230 V. Maximum ambient temperature is 104 degrees Fahrenheit.

Questions about this item

How much heat and power does the 1 HP TEAO motor draw when running continuously at 1725 RPM?

The motor draws 9.0 amps at 115 V or 4.5 amps at 230 V single-phase, delivering 1 HP at 1725 RPM with a maximum ambient temperature of 104 °F.

What electrical supply and wall opening are required to install this 48-inch belt-drive exhaust fan?

You need a 115/230 V, 60 Hz, single-phase circuit and a wall opening of 52-7/8 inches high by 52-7/8 inches wide for the 52-1/8 inch square housing.

Will the 48-inch propeller and 608 RPM speed work with my existing 16-inch shutters and 4-1/2 inch deep venturi?

The fan requires a venturi clearance diameter of 5/16 inch and a depth of 4-1/2 inches; the 48-inch propeller at 608 RPM is designed for this specification, not 16-inch shutters.
