Damper: Gravity Damper (Wall Type)
Wall Type Gravity Dampers are designed to open automatically when the fan is energized and to close
by gravity when power is turned off, these parallel blade, end pivoted dampers provide a mechanism
which prevents the air from back flowing through the system while also serving to exclude outside
elements such as rain and snow.

Damper: Gravity Damper (Ceiling Type)
Ceiling Type Gravity Dampers are designed to open automatically when the fan is energized and to
close by gravity when power is turned off. These parallel blade, end pivoted dampers provide a
mechanism which prevents the air from back flowing through the system while also serving to
exclude outside elements such as rain and snow.

Damper: Manually Operated Dampers
Outlet dampers are available in both “parallel” or “opposed” blade configurations and are manually
controlled. Manual dampers are typically used to balance a system.
