The FRD Model Flat Face Radial Pattern Diffusers have been designed to provide low aspiration at high ventilation rates, especially for clean room applications such as research laboratories, animal labs, food processing, hospital rooms and computer rooms. Specially designed internal baffles and a pressure plate produce an excellent radial air pattern that allows large volumes of air to be supplied at low level velocities. The unobtrusive flat face design provides the smooth appearance required for architectural excellence.

The FRD-2 model introduces air in a semi-cylindrical 180º radial flow pattern, flushing a room with large volumes of clean conditioned air, minimizing entrainment and hence mixing with contaminated air, whilst still allowing low room air velocities.

The FRD-1 model introduces air in a 90º radial flow pattern for perimeter applications.
