The Multi-leaf damper is used primarily for volume control.
It consists of a formed channel section frame, containing
linked single skin formed blades, which can be arranged for
either opposed or parallel operation. The unit is operated by
an external lever which is suitable for connection to electric
or pneumatic actuators, or to a locking quadrant for hand
operation.
Construction:
Casing and blades are made from galvanised sheet steel:
casing = 1,0mm
blades = 1,0mm
Blade spindles and external linkages are made from galva-
nised steel.
Plain bushes are made from ACETAL RESIN (max temp 110°)
but can be made of brass if requested.
Locking quadrant may be supplied as an option. The locking
quadrant is used in conjunction with a U-channel for manual po-
sitioning and locking of the blade postion. Actuators (if ordered)
will be supplied and mounted on all dampers of single construc-
tion. Where dampers are split (see config 1 & 2 on page 3) the
actuator will be supplied separately with mounting bracket for
assembly on site by others.
Drive arm is made from galvanised steel. (An extended spindle
can be supplied as an option for use by the client. However,
this is standard when the damper is supplied with an electric or
pneumatic actuator).
