Abstract
The present invention relates to a supply or exhaust air terminal device (300) comprising a flow indicator (320) adapted to indicate when the air flow (310) in relation to a predetermined threshold level is below a predetermined threshold level. The flow indicator (320) comprises a flow sensing means (321) adapted to generate a signal related to the air flow (310) and a visibly arranged signalling means (322). The flow indicator may further comprise an electronic circuit (323) adapted to compare the signal from the flow sensing means (321) with at least one predetermined threshold value corresponding to the predetermined threshold level. Thanks to the present invention it is possible to provide a supply or exhaust air terminal device that simplifies inspection and adjustment while improving the reliability that correct air flow is obtained.
