The KE-DireJet® System is produced in the
following configurations: round (Ø),
half-round (D), or quarter round (½D)
ducts and is made of a permeable textile material with rows
of conical nozzles for active and directional delivery.
From a ventilation technology perspective, the
KE-DireJet® System can be regarded as an
active high impulse system for mixing ventilation.
KE Fibertec is the only distributor of fabric ducts that offers
five different nozzle sizes:
The flexibility in the choice of nozzle size offers great
benefits as the KE-DireJet® System can then
be used in virtually every type of premises that requires mixing
ventilation, even in extremely large ones, such as high-bay
warehouses or large sports arenas.
The conical nozzles are fitted in holes made of polyester
fabric and are secured using a locking ring. The maximum number of
nozzles per row per foot is 4 for the ½, ¾ and 1" nozzles. If this
is not sufficient, it is recommended to use two or more rows of
Where the 2 and 2½" nozzles are used, it is
recommended to use a maximum of two (2) nozzles per foot per row.
As the number of nozzles per foot is increased, the individual jets
will have an impact on each other, and they will change character
from circular (3-dimensional) jets to 2-dimensional jets. The
velocity rate in the flow will also slow down as the induction of
room air is limited the closer the nozzles are placed
