Item Description

Manufacturer: Cool Components Inc
Part#: VS-IDF-4-PRO

This is for moderate venting in professional applications.  4" ducting is very versatile and this unit can be used in a variety of applications such as venting rooms, closets, projector enclosures, video walls...  For most professional applications we recommend the EC units but this unit is ideal for when advanced and variable speed control is not beneficial.

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 for the 4" professional version which utilizes 4" ducting or by connecting 3 ducts to a single 4 duct. This makes it perfect for venting from two locations with one unit.  This unit features a maximum speed of 2200rpm with approximately 117cfm (at max speed) and a noise rating at or below 31db.  The motor utilizes a 2 speed (fixed high and low speed) sealed ball bearing design with an estimated life span of 50,000 hours.  It also features an IP44 harsh environment rating to protect against basic moisture and particle intrusion.  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.  This unit is ideal provides a significant and usually adequate amount of airflow for most applications.  The primary difference in the professional version is the housing which is made from polypropylene which increases the durability of the unit.
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.
