Specifications determined using the following information :
Air throw
:
* with JET+ diffuser for a residual speed of 0.1 m/s
Air speed
:
JET+ diffuser outlet
* defined with êt OT/RT of 15°C (heating) and 7°C (cooling)
Sound pressure
:
measured 5 metres from unit, directivity 2, attenuation of 22 dB
* with LP water or electric heating
Direct: speed obtained when wired directly to single-phase motor.
R3*: air supply speed obtained with autotransformer set to “3”. Other operation points (5 in total) can be supplied on request by your agent using our technical selection software.
