VELOCITY DUCT UNIT
The Velocity duct unit allows air in a ventilation duct to be monitored for smoke via a smoke detector mounted externally in a sealed chamber.
The unit comes supplied with 2 sampling probes (one in & one out) which are mounted through the duct in the centre of the air flow.
Please note for reliable smoke detection the air speed in the duct must be at least 2.5m/s.
