Aluminium Jet Diffuser

Application

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

Product Description

The Aluminium Jet Diffuser (AJD) is a high-performance air distribution terminal designed for long-throw supply air applications in HVAC systems. Manufactured from high-quality extruded and spun aluminium alloy, the jet diffuser delivers concentrated airflow over long distances while maintaining low noise levels and high occupant comfort. . Its concentric cone arrangement & adjustable nozzle provides a uniform 360° radial air pattern, good room air mixing, and low-pressure air distribution. The diffuser is suitable for installation in false ceilings, exposed ceilings, commercial buildings, offices, hotels, hospitals, shopping centres and industrial areas.

Navajyothi Jet Diffusers has 2 pattens Jet (Nozzle) pattern, Diffuser Pattern. Jet pattern throws are typically double that of diffuser pattern which can be set according to air velocity.

Our Jet Diffusers comes with Complete outer spun housing frame & spun multi cone assembled with Round pipe and locking nuts on threaded rod.

Air flow adjustment by rotating inner core manually for left / right or up / down function
