Roof Exhaust Fan 550 cfm 10 in
The Dayton 4YC86 is an axial downblast roof exhaust fan built for commercial and light-industrial ventilation. Its 10 in blade diameter and 1/8 hp motor deliver 550 cfm at zero static pressure. The unit arrives fully assembled with a totally enclosed air-over motor rated for 115V AC single-phase power.
Installers needing low-static roof exhaust
Contractors fitting restaurants, workshops or warehouses where static pressure stays below 1/2 in wc will find the airflow adequate. Buyers who need high-static pressure capability, multi-speed control or operation above 120 Degrees F inlet temperature should look at alternative models. The single-speed design also limits balancing flexibility.
Maximum static pressure 1/2 in wc
This figure defines whether the fan can overcome duct resistance in a specific installation. If the system static pressure exceeds 1/2 in wc the unit will not deliver the rated 550 cfm and a different fan must be selected. Verify the installed ductwork pressure drop before purchase.

Questions about this item
How much air will the 550 cfm rating actually move through my roof duct?
The 550 cfm rating is measured at zero static pressure; in a real duct run the airflow will be lower depending on duct length, elbows and any filters installed.
What does the 1/2 in wc maximum static pressure limit mean for duct design?
The fan can overcome up to 1/2 inch water column of resistance; total system pressure drop must stay below that value or airflow will drop sharply.
What roof opening and clearance does the 10 in blade diameter require?
The 10 inch blade diameter typically needs a roof curb or opening slightly larger than 10 inches plus clearance for the aluminum housing and motor enclosure.
