Air Distribution

We have developed a better solution for the comfort of the passengers.

AirDIV is a fully-specialized supplier of air distribution systems for mass transport vehicles, ensuring an even distribution of air along the entire length of the vehicle. Our solution has been developed through countless laboratory tests, computer simulations and many years of experience. It offers a unique way to deal with the specific circumstances and limitations of the field.

The diameters of the perforation holes vary along the length to ensure identical air distribution along the entire length of the duct.

  • Most used distribution air outlet method
  • Laser perforated holes with a diameter greater than 2 mm
  • Provide directed and evenly distributed air supply


Designed to remove the deflection of air leaving from the perforation. The solution is based on the interaction of two air flows of similar momentum. Discharge from the last hole in the row is directed at a certain angle using a fabric pocket and balances the air deflection from the perforation.

  • Solution for deflection of air flows from perforation
  • Ultrasound-connected
  • Patented feature


Great way of achieving greater flow range. The airflow is extended by about 25% in comparison to standard perforations and deflection is minimized.

  • Allow directed air patterns
  • Exist in three diameters: 20, 30 and 40 mm
  • Ultrasound-connected


Designed mainly for use as low-velocity air diffusion.

  • Very small perforations
  • 200 – 400 µm laser cut holes in the fabric
  • Patented (Bevel microperforation)

options when designing air distribution elements on duct

The air velocity at various distances from the air duct can be calculated by our own design software which is being constantly refined and takes into account all associated design influences. These include specifically, pressure in the diffuser, supply air flow from ventilator, position, and dimensions of outlet openings. In cases where the air velocity cannot be reliably calculated by the software, we can provide these calculations by means of our Fluent software (CFD simulations).

Computational fluid dynamics (CFD) simulations provide a true-to-life picture of the airflow distribution, pressure, and velocity inside the passenger compartment or driver’s cabin.
