Flex Duct Installation for Ceiling Neutralization
The Retrotec Flex Duct enables you to quickly neutralize the pressure difference across a
ceiling. The kit is comprised of a 12 foot, 24 inch diameter flexible foil tube, and a
protective case. The Flex Duct is quick to install and is compatible with any Retrotec fan
model.
Before You Begin
A Flex Duct test requires that two fans be installed in the
door opening. The upper fan measures lower room leaks
while the lower fan neutralizes leaks above the ceiling.
