Motion Detectors
Motion detectors may be used with Models SP and CSP fans, or fan and light combinations. Motion detectors
use a passive infrared motion detector that will automatically turn on the fan when a change in temperature is
sensed. They have a viewing area of 180 degrees, however they must be placed in the line-of-sight. They also
have an adjustable time delay shutoff setting of 1 to 20 minutes.
Ceiling Radiation Dampers
The Greenheck SP-A and SP-B ceiling
radiation dampers are UL Classified, rated
at three to four hours fire resistance, and
is available on all SP-A and SP-B fans and
fan/light combinations. This design saves
space by allowing the damper to mount
directly beneath the fan.
All dimensions shown in inches.
Add an “L” to all CRD models if fan & light combo is used.

Filters
Fans used in most applications, even where air is not excessively dirty, will collect airborne dirt on wheels and
motors over time. Accumulations of dirt on the fan wheel will sharply reduce performance and cause imbalance.
Dirt buildup on the motor can cause it to overheat. All of these conditions will
shorten the life of the fan. To help reduce this accumulation, washable aluminum
mesh filters are available to trap dirt before it enters the fan. These filters should
be regularly cleaned to maintain performance. The Filter Loss Chart shows the
effect the filter will have on performance. To determine the added resistance,
divide the desired cfm by the filter area (ft
2
). This will give FPM. Use this with
the filter loss chart to get the added resistance. In addition to reducing dirt
accumulations on the motor and wheel, filters also reduce sound levels.
