Can this fan be used with an external multiple fan speed control? How much speed flexibility does the motor have? I would like to be able to run the fan at different speeds depending on the relationship between attic temperature/humidity and external temperature/humidity.

Answer:
Thank you for the question on the 353 attic ventilator. This unit can be controlled by a solid state speed control (our model 72W). At low speed it would run at approximately ½ speed.

I see from the specs that there are very small differences between the two models, such as 1000 versus 1050 CFM, roof cut-out diameters, housing and dome dimensions, metal versus PVC dome material, and max amps and volts. Can you help me figure out the most important differences so that I can select the right model for my application?

Answer:
Hello Ben –
You have hit on all the important points. The attic size would be the other difference between these two models. The 349BR is for attics up to 1400 square feet. The 350BR/350BK would be for attics up to 1500 square feet. If you are still unsure what is best for your application, please contact our technical support department directly at 1-800-637-1453. Technical is available Monday through Friday, 7:30 am until 6:00 pm CST. They would be happy to get into further details with you to help assist you more.
