JD

Product catalog summary

Technical Specifications
Product JD is constructed from aluminum and finished with RAL 9010. The JD series spot diffusers feature adjustable nozzles designed for air distribution in large rooms, offering long throws and high induction rates. These diffusers are ideal for very large spaces and high air flows. They consist of a semi-spherical cap with a truncated cone nozzle, adjustable manually in all directions. The diffusers are made of aluminum with a crush-proof rotation gasket and can be installed on walls or circular and rectangular ducts. Versions with one, two, or three nozzles, as well as servo-motor versions, are available.

Performance and Installation
The air throw at minimum and maximum air flow is specified for sizes 160, 200, 250, 315, and 400. The quick selection criteria include a noise rating (NR) of less than 20 and a pressure drop of less than 15 Pa at minimum and less than 100 Pa at maximum air flow. Throw values are based on a terminal velocity of 0.5 m/s at the same room temperature.

Product Variants and Dimensions
Several models are available, including JD 110, JD 120, JD 130, JD 210, JD 310, and JD 140 B3 motorized versions. Each model has specific dimensions for different sizes (160, 200, 250, 315, 400), detailed in the technical draft section. For example, JD 110 is installed directly on ducts with a round opening, while JD 120 is for wall installation with a flange and screws.

Motorized and Multi-Nozzle Options
The JD 140 B3 model includes a proportional Belimo motor LM 24 SR signal 0-10 V for motorized nozzle adjustment. Models JD 210 and JD 310 offer multiple adjustable nozzles for enhanced air distribution.
