The VHL lamella hood is developed specially to achieve an architectally correct ending of air intake and outlet on the roof.
The lamella hood is as standard delivered in galvanised design, can also be delivered in black powder coating.
In order to achieve a harmonic transition from duct to hood, the connection to the hood can be choosen either as a duct or as a roof transition (e.g. GISOL or GISOLP) with its dimensions corresponding to ØD, below the roof the duct may be reduced to Ød1 (see mounting proposal 1).
The lamella hood can well also be mounted directly on a duct with the diameter Ød1 (see mounting proposal 2).
When connecting to the roof through connection TGR, the special transition piece TGR-VHL must be used (see page TGR).
