16 In Direct Drive Reversible Fan

This Dayton exhaust and supply fan moves air in either direction for ventilation or fresh-air intake. The 16 in blade diameter suits commercial and industrial spaces that need balanced airflow. It operates on 115/230V AC single-phase power with a 1/4 hp motor rated for 1750/1741 RPM. The galvanized frame measures 20 in high by 20 in wide with a maximum depth of 12 13/16 in.

Verify voltage phase and mounting clearance

Confirm your supply is 115/230V AC single-phase before wiring. The motor draws 2.8 A at 115V or 1.5 A at 230V, so size the circuit and disconnect accordingly. Ensure the opening accommodates the 20 in by 20 in frame and 12 13/16 in depth with enough clearance for the totally enclosed air-over motor. No drive package is included, so plan for direct mounting.

Sustained output at static pressure

At .000 in. SP the fan delivers 2027 CFM exhaust and 1811 CFM supply. Under .250 in. SP those figures fall to 1370 CFM exhaust and 1340 CFM supply, showing how duct resistance reduces sustained airflow. The ball-bearing motor is rated for continuous duty up to 104 Degrees F ambient temperature. Reversible operation lets you switch between exhaust and supply without changing hardware.

Questions about this item

What comes with the 16 in Dayton direct drive reversible fan and what must I source separately?

The unit ships as a galvanized frame with a 16 in blade and a totally enclosed air-over motor rated at 1/4 hp. No drive package is included, so you will need to supply mounting hardware, wiring and any ducting required for your installation.

Should I choose the 115 V or 230 V version of this 16 in Dayton exhaust/supply fan?

Both voltages share the same 1750/1741 rpm, 2.8/1.5 amp draw and 1/4 hp motor. Select 115 V if your circuit provides 115 V AC and a 2.8 A breaker; choose 230 V for a 230 V AC supply and a 1.5 A breaker.

What do the 2027 CFM exhaust and 1811 CFM supply ratings mean once the fan is installed in my system?

Those figures are measured at zero static pressure (.000 in. SP). At a typical .250 in. SP the output drops to 1370 CFM exhaust and 1340 CFM supply, so size your ductwork and dampers around the lower numbers.
