J&D Twister Exhaust Fan with Butterfly Shutter, 12" to 24"

What it is

The J&D Twister Exhaust Fan is a direct drive wall exhaust fan with a round, heavy-gauge housing and butterfly shutters, for garages, workshops, industrial buildings, greenhouses and barns. J&D has built it unchanged for decades. It comes in 12", 16", 20" and 24" sizes and ships fully assembled.

Shutter and airflow

Its 18-gauge galvanized butterfly shutters open easily when the fan starts and spring closed when it stops, with an adjustable, positive draft-free closure that creates a tight seal against the weather. At 0.10" of static pressure J&D rates the Twister at 780 CFM (12"), 2,050 CFM (16"), 2,630 CFM (20") and 4,470 CFM (24").

Service and safety

The balanced aluminum prop has a zinc-plated hub for smooth, vibration-free running, and the heavy-duty motor mount doubles as the safety guard with an easy-to-clean coated finish. For cleaning or service, remove two bolts and the hinged rear guard swings the fan assembly out. The guard meets OSHA 1910.212(a)(5) on the motor side; mount the damper side at least 7' above the floor.

Power and installation

The motor is totally enclosed, maintenance-free and high efficiency with sealed ball bearings, UL and CUL recognized, and runs single phase at 115/230V. The Twister has no cord: cut the rough opening, fasten the fan to your structure with your own hardware, and have it wired in. A J&D galvanized weather hood is available for the outside. J&D covers the fan for 1 year against defects.
