I have a 3' straight duct run from the main trunk in a mobile home to a bathroom. It just does not have any air moving throuh it! How can I vastly improve the air flow into the bathroom?

Thanks.

You may need a deflector in the main to direct air there. Or, put a booster fan in the duct.

First, id make sure that tiny diameter duct isnt partially restricted with debris inside it (or partially crushed) ... then id run a larger diameter duct providing you have access to the main trunk duct where the branch duct is attached. You may want to run something fairly flexible thru the duct opening back to the main duct to make sure it is fully open without restriction.

Hey, wait a minute.

This is awkward, but...
