Flex Duct Connectors are available for the inlet or outlet of the DB. These connectors provide a flexible connection between the fan and
the attached ductwork. This reduces the transmission of noise and vibration to the ductwork as well as allowing for slight misalignment
and easy removal of the fan without disturbing the rigid ductwork. Flex Duct Connectors consist of reinforced neoprene fabric and aluminum bands.

The sound power level ratings shown are in decibels, referred 10-12 watts calculated per AMCA Standard 301. Values shown are for inlet LwiA sound power levels for Installation Type B Free Inlet, Ducted Outlet. Ratings do not include the effects of duct end correction. The sound ratings shown are loudness values in fan sones at 5ft. (1.5m) in a
hemispherical free field calculated per AMCA Standard 301. Values shown are for Installation Type B Free Inlet fan sone levels. Sound data is based on resilient mount ODP
motors. Rigid mount TEFC and Explosion Proof motors may have higher sound levels.

The sound power level ratings shown are in decibels, referred 10-12 watts calculated per AMCA Standard 301. Values shown are for inlet LwiA sound power levels for Installation
Type B Free Inlet, Ducted Outlet. Ratings do not include the effects of duct end correction. The sound ratings shown are loudness values in fan sones at 5ft. (1.5m) in a hemispherical free field calculated per AMCA Standard 301. Values shown are for Installation Type B Free Inlet fan sone levels. Sound data is based on resilient mount ODP motors.
Rigid mount TEFC and Explosion Proof motors may have higher sound levels.
