Key Specs:
Category: Swirl Diffusers
Type: Plastic Swirl Diffuser
Product Specifications
The Swirl Diffuser delivers high-induction airflow using multiple vortex jets set at a 40 degree angle from horizontal. These jets entrain room air, creating turbulent motion and effective mixing above the occupancy zone for uniform temperature distribution and minimal draught. Its low-profile, compact design integrates seamlessly with ceiling fittings, offering both high performance and refined aesthetics.
Application
Ideal for residential and light commercial spaces with ceiling heights between 2.4 m and 4.0 m. Suitable for cooling and reverse-cycle heating applications where supply air temperature is within 20 degrees celsius of room air and the supply fan runs continuously. For consistent airflow characteristics, diffuser types should not be mixed in the same system.
Features / Benefits
- High-induction swirl pattern promotes rapid mixing of supply and room air
- Reduces draughts and prevents cold?air dumping
- Stable discharge characteristics across a wide range of air velocities and temperatures
- Lower static pressure than typical commercial swirl diffusers for improved system compatibility
- Compact, low-profile appearance complements ceiling lights and fittings
- Removable outlet face for cleaning and ceiling painting
