Product Identity

The Dayton 16D534 is a centrifugal downblast roof exhaust fan with a 10 inch wheel diameter and direct drive assembly. It is built for clean air exhaust on rooftops where a compact square base fits the roof curb. The unit arrives fully assembled with motor and drive package included for immediate installation. It suits installers who need a self-contained roof ventilator without separate drive components.

Voltage and Airflow Limits

This fan operates on 115V AC single phase power with a 1/8 hp motor delivering 1059 cfm at 0.000 in static pressure. Maximum static pressure capability is 5/8 in wc, so it is not rated for high static pressure duct systems. The 17 inch square base dimensions define the roof opening required for proper mounting and sealing.

Installation Notes

Direct drive design eliminates belt tensioning and alignment steps, reducing mechanical setup time on the roof. The assembled unit weighs less than belt drive alternatives, allowing single person placement on the curb in many cases. Installers must verify the 115V supply matches site wiring and that the roof structure supports the 17 inch square base footprint without additional reinforcement. Buyers needing higher static pressure or three phase power should select a different model.

Questions about this item

Should I choose the 10 in wheel diameter or the 17 in base size for my roof installation?

The wheel diameter is 10 in and the base is 17 in square; both dimensions belong to the same unit, so you do not select between them.

What does the 1,059 cfm airflow figure mean when the fan is mounted on a roof?

It delivers 1,059 cfm at zero static pressure; actual airflow will drop once ductwork and roof resistance are added.

How does the 115V AC single-phase supply limit the fan's performance?

The motor runs on 115V AC single phase and is rated at 1/8 hp, capping the maximum static pressure at 5/8 in wc.
