18 in Direct Drive Reversible Fan

This 18 inch direct drive reversible ceiling fan suits exhaust or supply applications in commercial or industrial spaces. It delivers 3477 CFM exhaust and 2960 CFM supply at zero static pressure. The unit operates on 115/230V AC power with a 1/3 hp motor.

Ball Bearing Motor and Galvanized Frame

The totally enclosed air-over motor uses ball bearings for durability up to 104 degrees F ambient temperature. A galvanized frame finish resists corrosion in damp environments. Motor drive package is not included and must be sourced separately.

Check Voltage Phase and Mounting Clearance

Verify your supply matches the 115/230V AC rating and 3.3/1.7 amp draw before ordering. Confirm the 22 by 22 inch footprint and 10 3/4 inch depth fit your opening. Buyers needing an integrated motor package or lower noise levels should consider other options.

Questions about this item

Will the ball bearings in the motor need periodic lubrication or replacement?

The motor uses sealed ball bearings that do not require lubrication; they are rated for continuous operation and typically last the life of the fan under normal conditions.

At what static pressure does airflow drop off most sharply on the exhaust side?

Exhaust CFM falls from 3477 at 0.000 in. SP to 2926 at 0.250 in. SP, so the steepest drop occurs as resistance approaches 0.250 in. SP.

How hot does the motor enclosure get when the fan runs continuously at 115 V?

The totally enclosed air-over motor is rated for a maximum ambient temperature of 104 °F; at full load it draws 3.3 A at 115 V and runs at 1750 RPM, so surface temperature will stay within that design limit.
