  • Grille direct the air with the help of fixed louver inclined at 0/15 deg
  • Made of Heavy extruded aluminum frame and blade. Fixed bar grille suitable for both supply and return application in cooling and heating.
  • Can be supplied without frame suitable for wooden frame fixing application.

Air Diffusor

In HVAC systems, the air supply diffuser is a device that delivers and ventilates conditioned air in an area, mixes indoor air, and manages air output. It works by reducing the air duct velocity by increasing the static pressure.

  • Made from Extruded aluminum frame and aluminum sheet core.
  • Aluminum/GI Plenum Available for Uniform distribution of air.
  • Multicone 4 way type design suitable for ceiling application with concentric arrangement for equal distribution of air in four direction.

03.

Air Dampers

An HVAC damper (also called a duct damper) is a movable plate, located in the ductwork, that regulates airflow and redirects it to specific areas of the home.

  • Dampers are typically used in zoning or “zone control” systems.

  • Fusible Link Type:
  • In fusible link type Fire Damper Blades are held in the open position by a straight bar link (fitted as standard)
  • In case of Fire when temperature reach 74deg, Fuse melting allow the spring to close the fire damper and create the barrier to the fire.
  • UL stamped Fusible link operated at 74 deg. Temperature.
    Motorized Type: Motorized Fire damper operates with panel and Temperature sensor, that sense the temperature in case of fire and passes the signal through panel to actuator to close the fire damper.
  • Single skin 3V type groove type blade for proper and closer interlocking of the blades.
  • Opposed blades construction makes Fire damper for controlling the flow of air with the least disturbance to flow in ducts.
