Air Dampers

Components inserted into air ducts or devices which permit modification of the air resistance of the system and consequently a change in the air flow rate (dampers) or complete shut-off of the air flow (valves) or control of the air flow rate and, in addition, complete shut- off the air flow (control valves).

In particular, the following types, can be distinguished:

Multiple leaf dampers, comprising of a number of blades (or shutters) of opposed or parallel leaf type.
Single leaf dampers (the flap being mounted at one end), commonly called splitter dampers.
Hit-and-miss dampers, having two or more slotted slide mechanism.
Butterfly dampers, with two flaps in "V" arrangement.

Air dampers are designed for regulating air flow in rectengular or circular ducts
