Operating Data

Data refers to 1 m long diffusers, with a terminal velocity Vt = 0.25 m/s, flush-mounted on the ceiling and with horizontal air throw (Coanda effect). Values refer to the diffuser without damper or with sliding damper fully open. Values refer to the diffuser with deflectors set in operating position, with 50% free area reduction. The deflector position reduces the effective area. With deflectors fully open, or when the diffuser is used for return air, the airflow rates (m³/h) shown in the table may vary.

  • Vk: effective speed (m/s).
  • m³/h: flow rate.
  • Pa: pressure drops in Pascal.
  • L(m): air throw in metres calculated on ceiling installation, terminal velocity 0.25 m/s.
  • dB(A): noise level.

Connection AngleK-CON-D – Continuity kit for EDFL-EDLS-EDLH series diffusers

Aesthetic corner element designed to provide a seamless connection between two linear diffuser runs at a 90° angle, with a 500 mm length on each side. It has no air distribution or ventilation function.

The continuity kit is an accessory required to create continuous linear diffuser runs longer than 2 meters. It consists of two joining plates that ensure the alignment and secure connection of two adjacent diffuser sections, providing a continuous and uniform installation.

Air Throw Characteristics

Esempi di Configurazioni di Lancio dell’Aria

L’immagine illustra un esempio delle diverse configurazioni di lancio possibili di un diffusore lineare a feritoia, ottenibili mediante la regolazione dei deflettori interni: lancio orizzontale monodirezionale, lancio verticale e lancio inclinato/divergente. La possibilità di orientare il flusso d’aria consente di adattare la diffusione alle diverse esigenze impiantistiche e ambientali.
