Product Description

A versatile diffuser designed specifically for applications which demand varying zone conditions by providing a helical air stream of supply air which reflect optimum conditions such as cooling, isothermal and heating requirements. The projection of supply air is developed and governed by adjusting the angle of the helical core within the outer conical housing. The relationship between the installation height and the helical core projection is critical to ensure correct conditioned air development within the occupied zone. The projection can be accomplished either mechanically or electrically. FXL-A swirl diffusers are capable of handling large volumes of air and are ideally suited for industrial applications as well as commercial properties which require high ceiling heights such as Atriums, Airport Terminals, Theatres and Shopping Malls. The external conical spinning is constructed from aluminium with an adjustable helical core manufactured from galvanized mild steel, housed within the assembly.

Application
Features
The construction of FXL-A swirl diffusers adopts hydrokinetics principle for the design of its blades, by which the blade pushes the air flow by means of swirl with a certain initial velocity to achieve a larger throw distance, bigger space covered by a jet, and more efficient convection flow effected.
Swirl diffusers can be used in either constant or variable air volume systems with excellent performance characteristics when air flow reduces from 100 % to 25 %. The noise levels are low. Blades can be changed its quadrant angle to adapt to different conditions by blowing rotating flow of horizontal, slant and vertical directions.

Condition A

For supplying cold air with temperature lower than room air temperature.

Condition B

For supplying fresh air with temperature similar to room air temperature.

Condition C

For supplying warm air with temperature higher to room air temperature.
Performance Data
Testing condition: – Noise: based on room absorption of 10 dB. – Pressure drop: static pressure drops are in Pascal. – Throw: throw at 0.5 m/2 terminal velocity in meters.
