J&D 50" Whirlwind Box Fan
Your review: This fan was purchased to help ventilate the fire station apparatus bay area. We have purchased other large drum fans in the past but none have moved nearly as much air as this unit. We have only had the fan in service for 2 weeks as of this review but so far we are very pleased.
Pros: This fan moves a lot of air, with only a moderate sound level. The unit also seems very sturdy.
Cons: We did have to add some additional rubber clips around the guards to keep them from rattling during operation. Another Con for us but may be fine for others, the motor on our fan came wired for 220v from the factory, the motor had to be rewired for 110v but it was an easy fix.
