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.  Vertical gravity dampers are commonly called shutters.  Gravity 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. They have fixed blades that do not close so if the application requires air shutoff, a combination damper/louver is recommended.
