Price FRFDC Series Flush Face Radial Flow Diffusers with replaceable high efficiency filters provide a unique method of air distribution for modern critical environments. 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 FRFDC combines the best features of both louvered and laminar flow diffusers. Its architecturally pleasing ceiling flush perforated face produces low initial face velocities, minimizing entrainment of room air, while its perforated face and internal louvered baffles distribute large volumes of air in a semi-cylindrical air pattern. A replaceable high efficiency filter allows the FRFDC to "flush" or displace contaminated air from the area with large volumes of clean, low velocity air.

  • Face of diffuser 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 factory scanned for leaks.
  • Optional steel full flow damper with remote cable operator.
  • Easily replaceable high efficiency filter with silicone gel seal, which provides a leakproof seal between the filter and housing.
  • Available filter efficiencies:
    HE           95% at 0.3 μm
    HEPA      99.99% at 0.3 μm
    ULPA      99.999% at 0.12 μm
