SKU CH-63Z5-66R6C

Roof-mounted exhaust ventilator moves 1,534 cfm at zero static pressure with a 1/4 hp motor

  • Delivers 1,534 cfm exhaust airflow at zero static pressure
  • High-efficiency 1/4 hp motor reduces energy consumption
  • Open dripproof enclosure protects motor from moisture ingress
  • Aluminium housing resists corrosion for long roof-mounted service
  • Single-speed 115 V 60 Hz operation simplifies installation

Roof Exhaust Fan for High-Volume Airflow

The Dayton 39FV54 is an axial downblast roof exhaust fan built for commercial or industrial ventilation. It moves up to 1,534 cfm at zero static pressure, making it suitable for removing heat, fumes or stale air from large enclosed spaces.

115V Single-Phase Power Requirement

This unit operates on 115V AC single-phase power at 60 Hz with a 1/4 hp open dripproof motor. Buyers without access to a standard 115V supply or who need three-phase operation cannot use this ventilator.

12-Inch Blade Diameter Limits Duct Sizing

The 12-inch blade diameter and 3/4 in wc maximum static pressure define the ductwork this fan can serve effectively. It handles short, straight runs comfortably but runs out of pressure in long or complex duct systems with multiple bends.

Questions about this item

What does the 534 cfm airflow figure mean when the fan is installed on a roof?

It is the exhaust and supply volume the unit moves at zero static pressure, so actual flow will be lower once ductwork or roof curbs add resistance.

How does the 115 V single-phase supply affect installation?

The motor runs on standard 115 V AC household current with one hot leg and neutral, so no three-phase panel or special wiring is required.

What roof opening or curb size is needed for the 18-1/4 inch high housing?

The 12 inch blade diameter typically requires a roof curb or opening that accommodates at least a 12 inch diameter throat; verify the manufacturer’s curb drawing before cutting.
