Dampers & Louvers: Dampers & Louvers: Dampers are available in motorized and gravity operated versions. Motorized (motor driven) dampers are typically used in applications where a very tight seal is required or when the damper has to operate against air pressure such as closing off a zone.Gravity dampers are typically installed in the horizontal fan exhust applications.ravity dampers do not have motors and require air pressure/air flow to open. Louvers are used on air intake or exhaust where protection from water infiltration is required.
