MAT's manually-operated dampers
are controlled by rotary actuation cables that can be routed inside or outside of the airstream.
However, such dampers
usually are usable in relatively small cross-sectional area ductworks only.
For example, the new 9” panels are designed to access or install dampers
such as the Arzel EzySlide (up to 6” round and 10” joist), Arzel Inserta Dampers
, Arzel Balance Pro Dampers
or equivalent brands/damper
The Simetal Drive Damper

were removed from series FPTUs and directly connected to the airflow chamber through a circular sheet metal duct with a length of 2.
Two characteristic settings will be available for damper
adjustment that can be activated at the flip of a switch.
In the economizer system tested in this study, the dampers
did not seal well, and 12 data points were collected for conditions with the outdoor and return-air temperatures nearly the same.

are connected to a common air plenum in the machine base, which is in turn connected to a single exhaust fan, either connected to the base or mounted remotely.
Vauxhall's FlexRide adaptive damping system is standard on all VXRs, giving drivers the choice of three separate chassis settings - 'Standard' for all-round performance, 'Sport' stiffening the dampers
for reduced roll and tighter body control while 'VXR' is FlexRide's most extreme mode.
You'll also need to keep the dampers
lubed monthly with GAA.
In recent years Qad-net has been diversifying into import substitution products in HVAC and have announced the addition of new product lines such as air filters, motorised fire and smoke dampers
and louvres which will be manufactured and have been tested in compliance with international technical standards.
