EXHAUSTO VTU and VTI diffusers are used as part of a ventilation system, where there is a need for balanced air replacement. The diffusers can be fitted directly to an EXHAUSTO spiro tube using the bayonet mount supplied with the diffuser.
VTU extraction diffusers can be ceiling or wall-mounted. VTI supply air diffusers are designed to be fitted in the centre of the ceiling.
The diffusers are fitted with a rotatable valve disc, which makes it possible to set the air gap to the required capacity. A foam rubber ring glued to the diffuser ensures air-tightness between fitting and bayonet mount.
VTU and VTI are made from white-lacquered steel sheet - RAL9003.
