LVU – Floor Low Velocity Unit (CE)

For total or additional makeup air

CE Marked (UKCA pending) – Uncontrolled drafts can completely interrupt the Capture & Containment capacity of hoods and ventilated ceilings. When carefully designed, Low Velocity Units LVU totally eliminate the kitchen occupied zone from drafts. They directly contribute to the highest reduction of the exhaust airflow rates.

LVU provides the maximum achievable level of comfort. A makeup air strategy that delivers superior comfort and assists with the capture and containment of the Capture Jet™ hoods and ventilated ceilings is undoubtedly worth the real estate it occupies.


Uncontrolled draughts – even the smallest ones – can totally ruin the Capture & Containment capacity of hoods and ventilated ceilings. A well designed make up air strategy contributes not only to guarantee this efficiency but also to the final Indoor Air Quality (IAQ) inside the kitchen. It should always be considered as an inherent part of the kitchen ventilation solution.

Low Velocity Units LVU are designed to be installed and integrated in the occupied zone. This configuration guarantees the lowest draughts and highest comfort in the kitchen compared to “traditional” diffusers. They are designed to break the speed of the fresh air carried by the supply ductwork, distribute it equally inside the units and «laminarise» the flow. The fresh air is then diffused at a very low speed in a very homogeneous way and without draughts.

  • Highest level of contribution in energy savings compared to traditional diffusers due to the best optimization of exhaust airflow rates reduction required by hoods and ventilated ceilings.
  • Best Improvement of the Indoor Air Quality (IAQ) and the perceived temperature.
  • Contributes directly to good working conditions and productivity improvement.
  • Construction in stainless steel. Easy access to the inside of the units due to the front faces mounted on hinges.
  • Internal system of airflow distribution made of a washable synthetic material, easy to remove and re-install.
  • Wide range of units to match any integration requirements. Possibilities of customisation.
  • Designed to facilitate easy cleaning.
  • Special dimensions or finishes on request.

Principle of operation


The static pressure loss varies between 40 to 80 Pa depending on the characteristics of the internal synthetic distribution sleeve.
(1) For air velocity of 0,20 and 0,40 m/s in the occupied zone.
