Figure 16: Model 2100 fan and Fan Top (no longer available).
The 2100 was Retrotec's original 2000 model fan used in the System Model R43. It is a ¾ horsepower fan, suitable
for most residential testing. It requires a manual speed control to adjust the fan speed.
To connect the 2100 to the DM-2 Digital Pressure Gauge
1. Connect the power cord from the fan to a compatible wall outlet.
2. Connect a pressure tube from the “Ref B” (yellow) port on the Fan Top to the “Ref B” (yellow) port on the
DM-2.
3. Connect the manual speed control to the Remote port on the fan (new speed controls connect via Speed
Control Cables, and are not compatible with the 2100 fan).
2.6 Model 2200 fan (no longer available)
A fully automatic version of the 2100, the 2200 fan can be controlled by the DM-2 automatically, with the Set Speed
and Set Pressure functions on the DM-2. If required, an optional manual speed control accessory can be connected
via a Speed Control Cable to allow manual control of the fan speed (so that the gauge is free to be used for zone or
Room Pressure testing).
