  Model HCRF - High Capacity Radial Diffusers with HEPA Filter  
  • Ceiling diffuser with a radial air discharge pattern where “room-side replaceable” HEPA or ULPA filters are required.
  • Rapid jet velocity decay - short throws
  • Intrusive radial pattern baths critical areas in continuous supply of clean air and lowers the concentration of airborne particles / contaminants
  • High ventilation rates with occupant comfort
  • Use in high air change spaces such as labs, pharmaceutical manufacturing, animal rooms, and industrial applications
Product Features
  • Installs flush to the ceiling as a single, fully gasketed module – no field assembly required
  • 180° & 90° radial patterns available for design flexibility
  • Unique, manually adjustable pattern controller to “fine tune” pattern based on design air flow rate, cooling differential, and application
  • Filter interface includes knife edge into filter gel seals for zero leak performance
  • Pressure port to measure filter static pressure drop
  • Removable face via 1/4 turn fasteners for cleaning
  • Face is hinged and swings down 90° for easy cleaning. Safety cables prevent face from accidentally swinging down.
  • Closed cell gasket prevents leakage around face
  • Available for lay-in T-bar or hard surface ceiling systems
  • Light Alert Filter Monitoring System
  • Aerosol injection system and concentration ports integral with unit to simplify field verification and certification
  • Balancing damper
  • Steel, aluminum, or stainless steel construction
  • White, baked epoxy finish, satin polish (stainless steel).
