No Air movement
I installed two of these in a 18x30 workshop I built. ~ 9' walls to exhaust dust I create when I am sanding. I mounted them in the ceiling, I install a 10"-8" reducer on the fan and ran insulated flex from the reducer to vent on the roof. The length of the flex is about 5 feet. I believe it was a Broan roof vent with damper I used on the roof. Even with the door open to make sure I have plenty of air movement I can see the exhaust fans blowing the air back into my shop, not sucking it out as I would expect.
Thank you for your question on the model 504 vertical discharge fan. Each fan should have its own individual duct work. If you have them both vented through the same duct run to the termination cap, you are getting back pressure causing the fans to blow air back in. If this is not the case, please contact our Technical Support directly at 800-637-1453.

The specifications for this fan indicate - "Motor engineered for continuous operation - NO". Would there be a safety issue if the fan were to be accidentally left on during a 4 or 5 day vacation. Also, what is the total service life of the fan motor?
Thank you for your question on the model 504 exhaust fan. There would not be a safety issue if the fan was left on, but if the motor got too hot, it may open the thermal protection inside the motor and cease to operate. Please contact the Technical Service Department at 800-637-1453 for further assistance.

Can I use this to circulate heat from room to room?
I have a wood burning stove in my basement with a 10" square hole in the floor (above the stove) to allow heat to rise into the first floor. I would like to install a fan between the floor joists (below the floor cut-out) to help move heat from the basement to the upstairs. Basically just want to transfer air from basement to upstairs.
Thank you for your question on the model 504 vertical discharge fan. This fan is designed to be installed with duct work to a roof cap and not for the purposes you have explained. Please contact the Technical Service Department at 800-637-1453 for assistance.
