Product Information -

Price RFDC Series Radial Flow Diffusers with replaceable high-fficiency filters provide a unique method of air distribution for modern cleanrooms. They are designed to provide large volumes of filtered air with low room velocities — a situation not always possible with laminar flow panels.

The Price RFDC combines the best features of both louvered and laminar flow diffusers. Its special perforated face produces low initial face velocities, minimizing entrainment of room air, while its radial shape and internal vanes distribute large volumes of air in a semi-cylindrical air pattern. A replaceable high-efficiency filter allows the RFDC to flush or displace contaminated air from the cleanroom with large volumes of clean, low velocity air.

  • Face of diffuser is easily removed for access to the filter.
  • Static pressure port to measure filter pressure drop.
  • Surface mount or 1" (25) wide gasketed T-bar ceilings.
  • Housing is factory scanned for leaks.
  • Optional steel full flow damper with remote cable operator. Selection of coated or stainless steel is available.

    March 2016 – Recent ASHRAE research has shown the impact of lower minimum air volumes by diffuser outlet type. The impact of these lower air volumes on the occupant and the energy consumption will be explored.
