Navajyothi Air Flow

Application

Supply and return air distribution for HVAC ventilation and air-conditioning systems.

Product Description

Aluminium Eye Ball Diffusers are precision-manufactured from high-quality aluminium for efficient and directional air distribution. The diffuser consists of a robust outer frame, adjustable eyeball and an integrated 2-flap butterfly-type airflow control damper, which enables regulation of the air volume. The eyeball can be manually adjusted to control the airflow direction and movement, providing flexible air throw in the required direction. The components are accurately fabricated, assembled, deburred and finished with powder coating or anodizing for durability, corrosion resistance and an attractive appearance. Aluminium Eye Ball Diffuser is a high-performance air distribution terminal designed for applications requiring long throw air projection.
