Radial Flow Diffusers

Radial Flow Diffusers

Price radial flow diffusers are high capacity outlets with short throws and one or two-way discharge patterns well-suited to minimization of airborne particle entrainment. Adjustable pattern controllers are optional. The RFDC Series includes the addition of an easily-replaceable filter for additional particulate control.

The air distribution system in an operating room has a significant effect on the frequency of surgical site infections. One solution for controlling infection rates is the Price Air Curtain System.

RFD Series

Price RFD Series radial flow diffusers have been engineered to supply large air volumes in confined spaces with minimal velocity. These diffusers produce a semi-cylindrical air pattern ideal for laboratory settings with fume hoods, and are available in aluminum or stainless steel construction.

What are
Radial Flow Diffusers?

Installed in or near the ceiling plane, these diffusers discharge air with a combination of horizontal and vertical components, making them a combination Group A /Group E outlet (ASHRAE Fundamentals, 2009). The diffuser face can be rounded or flush against the ceiling, with fixed or adjustable blades and 1-way or 2-way diffusion patterns. Radial flow diffusers are commonly used in environments where short throw and high capacity are required.

  • Ceiling Space

    Radial flow diffusers, while not yet categorized by ASHRAE for isolation environments, have a strong precedent for use as they typically require less ceiling space than laminar flow diffusers to achieve equivalent flow rates.

  • High Capacity

    Radial flow diffusers are designed to handle high airflow rates and as such are ideal for requirements where frequent air changes are required.

  • Short Throw

    Horizontal and vertical velocity profiles of diffusers in laboratories cannot exceed 50 fpm inside the occupied zone, in order to prevent drafts or fume hood interference. Radial flow diffusers have a relatively short throw in comparison to other diffusers and thus are ideal for laboratory applications.
