Choosing a Clothes Dryer for Long Exhaust

MDhomeguy's picture

The condo where I live requires that replacement dryers be capable of venting a minimum of 33 feet. I'm pretty sure the CFM rating of the dryer relates to this, but I don't know how to equate the rated CFM to exhaust length. How many CFM would I need for a vent length of 33 feet and 2 bends? Is there a published list of dryers by CFM or vent length capabilities? Thanks, Randy

thats quite a long run.  Each dryer has there own max lengths listed in the install manual.  Check that and find the subtraction for the two 90's or 45's.  

 

worst case, there are booster inline fans for exhaust.

You need a Boost Fan (post #216151, reply #3 of 4)

Get an inline dryer boost fan.  You'll need an access panel for cleaning it and a 110v(?) power supply to drive it.

Ventless dryers are common in Europe. You might consider this alternative.

Cool. I just discovered that if I use the paste feature from the edit menu, it bypasses the forum paste popup.
