Robert Jones Posted December 16, 2012 Report Share Posted December 16, 2012 11th floor condo. And this vent or air circulator type system is installed. It is controlled by a timer type switch. I have never seen one of these. Any one have experience with it? Click to Enlarge 36.02 KB Click to Enlarge 29.86 KB Quote Link to comment Share on other sites More sharing options...
Brandon Whitmore Posted December 16, 2012 Report Share Posted December 16, 2012 It looks like a booster fan. For what, I don't know. Quote Link to comment Share on other sites More sharing options...
hausdok Posted December 16, 2012 Report Share Posted December 16, 2012 What's written at the arrow on the fan itself. The arrow on the controller box points upward for the airflor while the other points downward. Hmmm. ONE TEAM - ONE FIGHT!!! Mike Quote Link to comment Share on other sites More sharing options...
Robert Jones Posted December 16, 2012 Author Report Share Posted December 16, 2012 I went to their website and it states it is some kind of air exchanger? There were no openable windows in the unit. It was installed above one of those in wall dryer vent boxes. Could be a booster for that? http://www.iaqsource.com/product.php?product=111075 Quote Link to comment Share on other sites More sharing options...

John Kogel Posted December 16, 2012 Report Share Posted December 16, 2012 I have also seen them on high end range hoods. Putting the fan some distance from the hood makes it quieter to operate. But they can be used for dryer or bath exhaust as well. Mike is correct, those arrows appear to be in opposition. ?? This one serves two bathrooms. It looks like they lose (loose? lews?) on pipe length here, but who am I to criticize? I'm sure it was an expensive upgrade.[] Click to Enlarge 51.85?KB Click to Enlarge 67.31?KB Quote Link to comment Share on other sites More sharing options...

Marc Posted December 16, 2012 Report Share Posted December 16, 2012 What's written at the arrow on the fan itself. The arrow on the controller box points upward for the airflor while the other points downward. Hmmm. ONE TEAM - ONE FIGHT!!! Mike It's the arrow on the motor that counts. Sometime the j-box, or the cover on it, is deliberately upside-down so the label isn't. I've installed several on dryer ducts. I don't know which applications was Rob's. If he can get the model number from that photo that might answer the question. Marc Quote Link to comment Share on other sites More sharing options...
allseason Posted December 16, 2012 Report Share Posted December 16, 2012 I just encountered one last week on a dryer vent, third floor of a four floor building. It has a timer that ran the fan for about 15 min after the dryer shut off. It also has a screen installed in the duct between the dryer and the fan to protect the fan from lint buildup.
