- Suitable for: ventilation, cooling, and short-range heating
DFC Perforation
Finally take control of your airflow.
Anyone who’s ever designed air distribution knows the problem—instead of flowing evenly, air clings to the duct surface. At the start of the system, you barely notice it. At the end, it’s too strong. Comfort is gone, performance too. And balancing? A never-ending compromise.
Not with DFC perforation.
This technology is based on a simple idea: air should flow straight into the room—not sideways, not diagonally, not unpredictably. A combination of precise perforation and directional flaps makes it happen.
Left: conventional perforation; Right: DFC perforation
The result? Air is delivered evenly, stably, and predictably—along the entire length. It flows exactly where it’s needed. And best of all: completely draft-free.
Behind the DFC technology is thoughtful simplicity.
The air is directed exactly where you need it - perpendicular to the space. And that's thanks to a combination of laser-cut perforations and directional baffles that are directly part of the fabric.
The airflow direction isn’t adjusted on site—it’s pre-defined during production.
It doesn’t fluctuate with pressure, requires no tuning during operation, and needs no additional components.
When the duct itself knows where to guide the air, the design remains simple and the result stays precise.
One technology, three variations.
Whether you're designing for a quiet classroom or a hall with a 20-meter ceiling, the principle stays the same: air flows straight into the space, thanks to the alternating pattern of openings and baffles.
We offer three variants, differing in airflow rate, reach, and discharge dynamics. Everything else stays the same.
HVAC Engineers know that the true quality of a design is revealed when the system starts running.
That’s where DFC perforation has a clear advantage—because it performs exactly as designed. Always perpendicular.
As a designer, you’ll appreciate:
Technical datasheets with detailed performance profiles
Precise airflow rates from 7 to 370 m³/h/m
Compatibility with hybrid or non-permeable systems
A system that does not condense, eliminating the need for insulation
Easy connection to various ducting types
Expert support that understands exactly what you need to know
Whether you're designing cooling for a school, draft-free ventilation for a canteen, or air supply for a warehouse, there’s always a high-performance DFC variant ready to fit your design.
