JD long pipe

Jet diffuser

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