What is the 12 Volt Fan?
The 12 Volt Fan is meant to accelerate airflow in all non-electric units. It comes pre-installed in an 11" piece of 4" diameter vent pipe so that it will fit inline in your vent stack. It also protects against downdraft and increases the evaporative performance of your non-electric unit by about 10 to 15% (still not enough to evaporate all liquids on an NE).
Its purchase is optional with an Excel NE, a Centrex 2000 NE, or a Centrex 1000 NE.

How Do I Install the 12 Volt Fan?
Choose a section of your vent where you will easily be able to access the fan, and connect it to the battery. Cut a suitably sized section of vent stack and insert the fan into the stack, ensuring that the piece is positioned correctly so that the fan is blowing upwards (coupling will be at the bottom). Caulk both seams with silicone for the best airflow.
Why can't I just use a computer fan?
Our fans are protected from moisture and weather, except in the case of air that is rich in salt (see above). While they may look like computer fans, they aren't.
