2 air master Panel type Model: AJD-P Construction: Frame: High quality heavy gauge aluminium sheet. Outer flange: High quality extruded aluminium profiles. Inner rings: Aluminium spun rings. Optional accessories: Plenum box either lined or un lined as per clients choice. Description: Frame and inner rings are high quality aluminium construction with the advantages of corrosion resistance. Jet nozzle section is mounted in aluminium square plate covered by flanged border. Nozzles can be adjusted 0 up words and down words to achieve required throw as per site condition. Nozzle jet can be rotated by 0 0 by adjusting the mounting frame. Generally designed for wall mounting. For ceiling mounting, drill 2 to 4 holes in the face of the flanged border. Air master jet diffusers are specially suitable to handle large quantity of air with long throw. Ideal for commercial use such as concert halls, theatres, exhibition and sport halls. Jet nozzles can be supplied with plenum box, which is manufactured from galvanized steel sheet as option. Plenum boxes can be supplied with round duct damper at the spigot as option. Standard finishes: Powder coated colour finish as per RAL colour codes. Flexibility of finishing is available. Standard sizes: Available from 100 mm dia to 0 mm dia with the increments of 50 mm. D = Dia of jet diffuser in mm ISO 9002 certified company 11.1

3 air master Fixing details: Screw fixing from flange to duct. Panel arrangement: 1,2,3 or 4 nos of jet diffusers will be arranged in a panel as per performance requirement.

6 Jet Diffuser -eyeball type Model: AJD Construction: Constructed with high quality aluminium sheets. Description: Airmaster eyeball jet diffusers are highly suitable for delivering a powerful stream of air over long distances. Its ability to deliver an accurate airstream makes it ideal for spot cooling applications. It's angular movement allows the airstream to be delivered through a wide area of direction either in full jet position or in reduced jet position. This diffuser spout is fully reversible, rotating through 0deg. The diffuser can be fixed directly to the round duct. The diffuser is suitable for long throw patterns with trajectory control. Gasket is sealed around the back of the spout to avoid air leakage. Finishes: Available standard finishes are RAL 9010, RAL 9003 & RAL 90. Special finishes are available as per RAL color codes.

10 Drum Louver Drum Louver Model: ADL Construction: Frame : Constructed with high quality extruded aluminium profiles. Drum : Aluminiium sheet and specially shaped extruded aluminium profiles. Blades: High quality extruded aluminium adjustable directional blades. Damper: Opposed blade damper made with aluminium profiles. Description: Blades are fixed inside the drum body made with aluminium sheets and specially shaped profles and the opposed blade damper is attached to the drum body. The whole assembly is fixed to the frame by mechanical fasteners so as to enable rotation in the vertical direction. The opposed blade damper in supply diffuser can be easily adjusted through the face of the unit by means of screw driver. The louver is suitable for both long and short throw patterns with trajectory control. Standard finishes: Aluminium construction with white powder coated finish (RAL 9010). Powder coated color finish as per other RAL color codes available as option. The drum can be adjusted in the vertical direction 0 o to o up or down to direct the air throw in the desired direction. Foam gasket is sealed around the back of the frame to avoid air leakage. 7 Rev. 1 ISO 9001:0 certified company 11.5
