(Incorporating Energy/Shield ES35 & ES36)
Control and
Shut Off Dampers
|
The
Air/Shield range of quality
engineered dampers are suitable for
air conditioning and ventilation
systems requiring air control and low
closed blade leakage characteristics,
for standard low/medium pressure
and velocity systems.
These aerodynamic precise
movement opposed blade dampers
can be either factory fitted with
manual, electric or pneumatic
controls and can be supplied in a
flanged or spigotted casing.
Application
Air/Shield
Dampers to maximum
width and height dimensions can be used where the
operating total system pressure is up
to 1000 Pascals and duct velocities
to 12m/second.
Actionair Air/Shield Dampers are
designed for applications in normal
dry filtered air systems. When
required for modulating function, or if
exposed to fresh air intakes and/or
inclement conditions, the dampers
should be subject to a planned
inspection programme.
Any application involving corrosive
and/or aggressive hostile
environmental conditions (e.g.
swimming pools) may invalidate our
warranty and should be referred to
Actionair Sales Office.
