DFC (Directional Flow Control) is a perforation that consists of alternating holes and baffles for 100% uniform air distribution.


Principle of functioning
The perforation has been developed specifically to prevent the entrainment of air in the direction of flow and the formation of dead zones (i.e. places where the incoming air cannot reach).

Entrainment is a common problem with conventional perforated fabric ducts. However, in the DFC perforation, this is prevented by flaps that direct the air perpendicularly into the room and the entrainment can´t appear.

Specifications of perforation
DFC perforation can be applied to all materials we offer at Euro Air. At the same time, the perforation is also suitable for all three standard shapes of textile ducts - round, half-round and quarter-round.

 The holes and baffles are cut with laser technology, which makes them very durable, and they will not be damaged by long-term usage or by normal cleaning in the washing machine.
