InRow SC Duct Length

[Anonymous user]

The included exhaust ducts of our of InRow SC are too short for our needs. What is the maximum operational length of the exhaust ducts? Would a 25 ft duct create too much backpressure? What about 15?

Also, the ducts look like they are 10" diameter, is this correct?

Thanks,

Anthony

Application Note 109 should cover what you need.

Also:

The fans in the unit are only rated for the length of the ducts that come with the SC. If extended ductwork is needed, then booster fans will have to be installed inline. We don't sell booster fans, the best bet would typically be to contact a local HVAC company who could sell and install the fans if you wanted.
