JD long pipe

Jet diffuser long pipe

The jet diffusers, type JD, are especially developed for large and high areas such as concert halls, theaters, galleries, airports, shopping centres, industrial plants,... Through their aerodynamic design they ensure a reduced noise level at high outlet velocities and establish a long throw. The jet is adjustable over 360°. With different supply air temperatures (cooling or heating) the jet can be oriented +30° upwards or -30° downwards.
