Plastic Vent Elbow - 4 1-VA-ELB-4 Plastic Vent Elbow - 4" $19.00
Item Description
Manufacturer: Cool Components

The only difference in this package and the VS-IDF-CVS-4-PRO which includes a ceiling box with optional filter. 25' of 4" insulated ducting, is it includes the newest technology EC Fan and EC temperature controller.  The Electronically Controlled Fan Unit (VS-IDF-4EC-PRO) deploys the latest fan technology in that it is still a high voltage fan but is low voltage controllable making it a much smoother running fan.  The controller is specifically designed for the EC fans and has features including on/off and variable speed control as well as various settings for how quickly the fans speed up, the speed the fans initially turn on at, basically all the features a professional would expect.  The controller can also integrate with control systems as Fan2 and Alarm Outputs are 12V outputs which can trigger various functions in most control systems providing different alerts...

It should be noted that the package is intended to provide what is needed to go from the ceiling in a room or closet to the fan unit.  The exhaust side and where and how it is run is very application specific so whatever is required to exhaust the unit should be ordered separately.  See Ducting Accessories for a variety of options included duct boxes, elbows, reducers...  It is recommended to duct the exhaust to the HVAC return system but if that is not possible, then simply duct it back into the house into a larger room or hallway...  Air should not simply be vented to the attic or outside of the home unless the attic is also sealed and conditioned or if in a very moderate climate.

For information on the normal package please visit the page for the VS-IDF-CVS-4-PRO and the fan unit, VS-IDF-4EC-PRO.
