Architectural Ceiling Diffuser

The Advanced Air Model Series 'UNI' Square Ceiling Air Diffuser has been specially designed to provide both the unobtrusive appearance required for architectural excellence and the 360° diffusion pattern at minimum NC levels required for high engineering performance. The stamped one-piece outer cone eliminates mitred corners and the die-formed curves provideconsistent quality and performance.

The UNI diffuser compliments any decor, blending beautifully with virtually any architectural style or requirement. The UNI diffuser provides stable diffusion and mixing patterns under constant and changing load conditions and is particularly suitable for variable air volume systems.

The UNI diffusers are available to suit many situations including surface mount, T-Bar lay-in and panel applications. Standardfinish is a high quality polyester powder finish for long life and easy cleaning. A variety of neck sizes are available to suit your system design. The collar is a full 32mm in height for easy, secure connection.
