Item Description

Manufacturer: Cool Components Inc
Part#: VS-IDF-LV

This is a Low Voltage Fan Unit and should only be used if very specifically require a low voltage unit.  The 3" high voltage unit bluntly put is a better unit overall and this is offered just for specialized situations where usually high voltage is not available.

Due to the trend of 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.  With proper planning they should also be easily serviceable. Duct fans, as the name implies, utilize ducting to connect the fan unit to the areas where wish to remove air (intake) and directs that air to another area or preferably, to the HVAC return vent (exhaust).  Generally the inline duct fans feature multi-speed motors and are powered with 110/120 current (220V versions are available via special order).   

There are several units available ranging from Residential to Professional versions with the primary difference being the residential 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 smooth 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 ducting.  Then at the end of the life of the fan, it is very easy to swap out the fan also without removing the ducting.  Another staple of these fans and the latest technologies is that the units are very efficient and are also fully recyclable.

This listing is the 3" Low Voltage version which utilizes 3" ducting that will easily fit inside 2x4 walls making it perfect for venting recessed cabinetry and projector enclosures. The motor utilizes a sealed ball bearing design with an estimated life span of 15,000 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 of air around the components paying special attention to eliminating any hot spots.  These are areas where air just remains still and not circulating throughout the system.  This unit is ideal to simply get a little air moving and even better for retrofit applications where supplying high voltage power can be a problem.
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.  If bench testing just note that the unit will appear very loud as the motor is not intended to spin freely and once ducting is added and thus back pressure applied to the unit, the noise will be greatly reduced.
