Directional Diffusers
The Directional Diffusers category features the essential air terminal devices used to precisely control the flow and dispersion of conditioned air into commercial and institutional spaces. These components are critical for achieving optimal thermal comfort, minimizing drafts, and ensuring effective air change rates in the occupied zone, all while integrating seamlessly into the ceiling architecture.
This range includes several fundamental types, each engineered for specific performance and aesthetic requirements:
Multi-Directional Diffusers (1-Way to 4-Way): These square or rectangular ceiling units use fixed or adjustable blades to discharge air in specific patterns (1-way, 2-way, 3-way, or the highly common 4-way pattern). They rely on the Coanda effect to adhere the air stream to the ceiling, maximizing throw and air mixing.
Round Diffusers: Providing a symmetrical and often omni-directional pattern, round diffusers are valued for their clean aesthetics and smooth, even air distribution, suitable for uniform spaces.
Perforated Diffusers: These units use a faceplate with numerous small holes, delivering air at a very low velocity and high induction rate. They are preferred in areas where sensitive, draft-free air delivery is paramount, such as hospitals or critical manufacturing spaces.
By selecting the appropriate directional pattern, HVAC designers can prevent stratification, guarantee uniform temperature, and reduce noise. Directional Diffusers are therefore vital in ensuring the intended comfort and efficiency of the entire air distribution system.
