Direct fresh air into small, cramped working spaces around corners, into a home attic, and throughout a basement for added ventilation and a more comfortable working environment during home improvement or construction projects. This flexible nylon duct hose slips around the front of your Maxx Air fan, is secured using a drawstring, and easily collapses into a bag for storage when it's not needed.

This duct is compatible with fan models beginning in BF24 and BF30.
