Ceiling Radiation Damper
The National Fire Protection Association (NFPA)
Standard 90A requires openings in fire rated ceiling
assemblies to be protected by appropriately rated
ceiling radiation dampers. As a result, many local
codes require fans installed in fire rated ceilings to
be protected by dampers which are insulated against
both heat and flame.
UL Classified ceiling radiation dampers are rated at
three to four hours of fire resistance. All model SP
fans and fan/light combinations are available with
ceiling radiation dampers. This design saves space
by allowing the damper to mount directly beneath
the fan.

All dimensions shown in inches (millimeters). Add an “L” to all CRD models if
fan & light combo is used. *CRD is approximately 1/4 inch (6 mm) larger than
housing dimension. (See Installation, Operation and Maintenance Manual)
Contractor 4 Packs
Save installation time and labor by installing the
housing first, then installing the internal components
after the sheetrocking, plastering and finishing is
done. Housings are packaged in one box, power
assemblies and grilles are packaged in another box.
Components are shipped to coincide with the phase
of your project. (Model SP-B only).
Wheel Options
Greenheck’s ceiling and cabinet fans (models SP and
CSP) deliver high performance from a forward-curved
wheel. The forward-curved wheel design offers
both high-efficiency and low sound. Fan wheels are
constructed of polypropylene or steel as standard,
and all models offer an aluminum wheel option.
• Level A models utilize steel or polypropylene wheel
construction depending on size.
• Level B models are standard with a
polypropylene wheel.
