Construction

1 – Panel

Made from high quality heavy aluminum sheet.

2 – Panel frame

Made from high quality extruded aluminum profile with 30 mm flange width as standard and non standard widths are available as option.

3 – Inner rings

Aluminum spun rings.

Description 

  • Framed and inner rings are high quality aluminum construction with powder coated color finish.
  • Generally designed for wall mounting for ceiling mounting. drill 2 to 4 holes in the face of the flanged border.
  • Nozzles can be adjusted 30 upwards and down words to achieve required throw as per site condition. Nozzle jet can be rotated by 360 by adjusting the mounting frame.
  • Jet nozzles can be supplied with plenum box. which is manufactured from  galvanized steel sheet as option.
  • Plenum boxes can be supplied with round damper as option.
  • Jet nozzle available from 100 mm diameter to 400 mm as standard and  non-standard sizes are available as option.
  • Jet nozzle available with 160 mm depth as standard and greater than 160 mm is available for higher throw.
  • Powder coated color finish per RAL color codes as standard and flexibility of finish.

Performance Data 

jet diffuser at 0 deflection

  • Neck velocity is measured in m/sec.
  • Ps: static pressure loss across the diffuser in mm of H2O.
  • Throw (meters) is measured for a terminal velocities of 0.25, 0.5 & 0.75 m/sec.
  • Noise criteria (NC) based on a room attenuation of 10 db.
  • Copyright reserved Specification subject to change without notice.

Performance Data 

Jet diffuser at 30 deflection

  • Neck velocity is measured in m/sec.
  • Ps: static pressure loss across the diffuser in mm of H2O.
  • Throw (meters) is measured for a terminal velocities of 0.25, 0.5 & 0.75 m/sec.
  • Noise criteria (NC) based on a room attenuation of 10 db.
  • Copyright reserved. Specification subject to change without notice.

Jet Nozzle – Ball Jet

  • Jet nozzles are developed for large and high area, such as airports, shopping centers, show centers, theaters etc.
  • It ensures a long throw (25m) at high outlet velocities.
  • The ball can be oriented 30°angle.
  • They are used for cooling or heating with the characteristic of orientation.
  • Rotated by manual or motor control.
  • Material:They are made of aluminum sheet.
  • Accessories:Damper (butterfly damper in plastic or steel manual control; radial-shape damper screw control).
  • Mounting: Ceiling or wall mounting by screws, or collected into a circular duct.
  • Finishing:White powder coating RAL 9016, RAL 9010, or customized color.

    Curve of air volume and throw for JD-VA Series ( Vx = 0.5m/s )

    Jet Nozzle Spec. Data (JD-VA)

    Data were chosen when the air velocity is 2.5m/s and the velocity at throw distance is 0.25m/s.

    Jet Nozzle Spec. Data (JD-VB)

    Data were chosen when the air velocity is 2.5m/s and the velocity at throw distance is 0.25m/s.

    Drum Jet Diffuser

    • Drum jet diffuser is designed to meet the requirements of low pressure drop, quiet operations, long distance throw and good air spread in large areas.
    • The air flow direction can be oriented up and down by rotating the cylindrical inner casing in a 60°angle.
    • The air flow direction can be oriented left and right by adjusting the blades on the inner casing.
    • Material:They are made of aluminum sheet.
    • Mounting: wall mounting by screws, or collected into a rectangular or circular duct.
    • Finishing: White powder coating Ral9016, Ral9010, or customized color.
