8 / 20 | Nozzle Diffusers
Accessory
THOR
Plenum Box
Description
The THOR plenum box is used together with air diffusers for pressure reduction, airow balancing and sound
attenuation as well as for measuring and adjusting the air ow. The standard air ow measurement accuracy
is preserved also when the straight duct length in front of the inlet is zero (directly behind Tee or Elbow piece
in the duct). The plenum box can be used for air inlet and extract.
Design
THOR plenum boxes are manufactured from hot-dip galvanized sheet steel with inlet connection sleeve tted
with a rubber seal tested for air-tightness. The inlet is equipped by the ZEUS damper with impulse tubes for measuring
differential pressure for ow volume calculation, using a portable measuring device. It can be adjusted manually using
a cable gearing.
