Under floor units


Energy efficient function in the false floor

In modern office buildings, false floors are a part of the standard equipment. The entire open space underneath the false floor, however, is not totally required for the installation of electrical and data cabling. For this reason, the integration of the ventilation system into false floor can be extremely interesting.

The units require no sill, what they are favored for buildings with full-height glazing. The low height corresponds to the dimensions of todays false floors.

The maintenance with filter change is quick and easy.

Type FSL-U-ZUM

  • A narrow, attractive linear grille discharges conditioned supply air into the room for heating or cooling.
  • This unit works extremely quietly.
  • Energy consumption is optimised by limiting the outdoor air volume which is mixed with recirculated air, with high heating and cooling performance standards.
