JET nozzles are used for hot or cold air supply in ventilation and air conditioning systems where a long throw, high induction and low sound levels are required.
The nozzles are manually adjustable to be set for cooling or heating purposes
Material
Coated Aluminium
Colour
Natural aluminium finish
Other colours available upon request
Composition
The nozzle can be adjusted manually to direct the air flow over 30° in all directions.
Text for tender

Symbols and specifications
Q = Air volume in m³/h
Ak = Effective surface (free area) in m²
Vk = Average effective velocity through the grill in m/s
X0.25 = Horizontal throw in m at an endvelocity Vt of 0.25 m/s
Ps = Static pressure loss given in Pa
Lw(A) = Acoustic power in dB(A)
The throw X0.25 is given without deflection of the airstream at an end velocity of 0.25m/s. The distances are given without coanda effect.
The values are given for isothermal supply air. Throw distances for cooling conditions at -11K can be calculated by deviding the X0.25 values with factor 1.1. For heating purposes at Dt of +11K a multiplier of 1.1 should be applied to the given X0.25 value.
The acoustic power Lw(A) are given for grilles without room attenuation. Acoustic powers below 20dB(A) are mentioned as "<20" in the tables.
