RA4 - Steel Round Diffuser

The Krueger RA4 Steel Round Diffuser offers exceptional control over airflow direction, making it the ideal choice for HVAC projects requiring both horizontal and vertical air distribution. This versatile diffuser features four adjustable cones, including an anti-smudge outer cone, allowing for infinite adjustability between horizontal and vertical airflow patterns. With a full 360° discharge, the RA4 ensures even air distribution throughout the space.

When fully open, the RA4 maximizes airflow capacity and delivers a strong horizontal throw. Conversely, closing the cones directs the air vertically, providing focused ventilation where needed. This adaptability makes the RA4 suitable for a wide range of applications, from offices and retail spaces to classrooms and auditoriums. Available in duct sizes ranging from 6” to 24”, the RA4 seamlessly integrates into new or existing HVAC systems.

Constructed from durable steel, the Krueger RA4 Steel Round Diffuser boasts a long lifespan and reliable performance. The standard finish is British White, providing a clean and unobtrusive aesthetic that blends seamlessly into any ceiling design. Specifically categorized under Masterformat Division 23 37 13 for Diffusers, Registers, and Grilles, the RA4 adheres to industry standards and is a trusted choice for HVAC professionals.
