Manufacturer: Cool Components
Part#: VS-IDF-3

Due to the increase in addressing cooling and venting earlier in projects, during pre-construction/ renovation, Cool Components has greatly expanded their line of duct fans.  Using duct fans is superior in most respects and primarily because the fans are quieter, move more air, very efficient and are simply out of the way since they will installed usually in an attic, crawl space, or basement.  Duct fans, as the name implies, utilize ducting to connect the fan unit to the areas where wish to remove air and directs that air to another area or preferably, to the HVAC return vent.  Generally the inline duct fans feature variable speed motors and are powered with 110/120 current (220V versions are available via special order).   

There are several units available ranging from DIY products to Professional versions with the primary difference being the retail housings are made from ABS while the Pro versions have a Polypropylene housing and come with optional EC (Electronic Controllable) fan motors.  This is the latest advancement in inline duct fans as it allows high voltage fans to be controlled with low voltage controllers.  Traditionally high voltage fans were only reliably controlled using 'step' control meaning there were 3 or 4 speeds that increased in a progression that usually left you hearing each time the unit took a 'step'.  The EC fans provide for a great linear progression so the fans start slow and ramps the speed up smoothly as the temperature rises.  As with all of Cool Components products, serviceability is also a key as the fan unit can be separated and cleaned without removing and having to re-attach the tubing.  Then at the end of the life of the fan, it is very easy to swap out the fan without removing the ducting.  Another staple of these fans and the latest technologies is that the units are very efficient.  They are extremely efficient when it comes to power and also fully recyclable.

This listing is the 3" version which utilizes 3" ducting that will easily fit inside 2x4 walls making it perfect for venting recessed cabinetry and projector enclosures.  This unit features a maximum speed of 2750rpm with approximately 46cfm (at max speed) and a noise rating at or below 26db.  The motor utilizes a sealed ball bearing design with an estimated life span of 50,000 hours.  It should be noted that massive airflow (cfm) is not always better.  With electronics the keys are simply adequate spacing of components and then usually just a basic flow or air around the components paying special attention to eliminating any dead/hot spots.  These are areas where air just remains still and not circulating throughout the system.
Please Note:  This fan is designed to be installed in an attic or remote location and has to be connected to ducting for proper air pressure and functionality.

The Inline Duct Fan is also available in convenient packages.
