2 JET JET JET SJN SERIES Dimensions SJN consist of a spherical discharge nozzle mounted in a housing and is complete with a front mounting flange and circular spigot for direct connection to circular duct. A rear duct connection with a spigot or a saddle with flange are available as option for fixing to the side of rectangular or circular ducts. Duct Diameter SIZE D D D E F L L SIZE Description The SJN Series jet nozzles are designed to ventilate large indoor spaces such as exhibitions halls, theatres, museums, foyers etc., outlets with long jet throws are needed. The discharge direction is determined by the outlet angle, (± 0 around the outlet axis) and can be adjusted manually or motorized. Finish: The standard coating finish is polyester powder coating, white color RAL 0 (Code: Z0). Optional Finish:. Natural anodized aluminium finish (Code: Z).. The powder coating can be of any color if requested as specified (Code: Z) For supply with actuator, L= 65mm for all sizes. E E The jet nozzle can be installed on walls, bulk heads and pillars. It also has extra ordinary good acoustic characteristics and is therefore well suited for air distribution in indoor spaces and critical areas such as stages, conference rooms, theatres, museums and broadcasting studios and concert halls. D D D D 60 D D Standard Construction Materials: The face cover and the nozzle are made of aluminum with natural finish and can be painted or powder coated (RAL 0) or to any other color. Motor Two plastic rings (color RAL 0) are used for mounting of the eyeball. All duct connections, spigots, collar saddles and flanges are supplied in galvanized steel finish. L F L 08 09

Description The RJN jet nozzle series is designed for areas where a long throw is needed. The large free area allows handling of large air flow rates with low pressure loss. Available with one, two, three or four elements per panel. Ajustable core can be rotated through 60 and tilted up to a maximum of 0 from mid position to produce a wide variation in airjet angles. Fully directional jet nozzles for high air flow rates and long throws. Finish: The standard coating finish is polyester powder coating, white color RAL 0 (Code: Z0). Optional Finish:. The powder coating can be of any color if requested as specifiied (Code: Z). RJN S Single element without panel for installation in a round duct. Standard Construction Materials: The face cover (panel) and nozzle are fabricated using gauge galvanized steel sheet and are powder coated to a white color, RAL 0.
