Important Notes:
- This unit must be used with the EC temperature controller, it should not be used with other controllers and cannot operate without a controller.
- We have upgraded the fans and controllers, in particular the controller which is compatible with older fans but the wiring is different.
This unit features a 4" professional grade EC fan which provides a moderate amount of airflow which if you go back to discussions about 'the basics', often times the goal is just to get the air moving and moving a massive amount of air is not necessary. The unit utilizes 4" ducting which can go into 4" walls if using uninsulated flex duct or can use 3" ducting and a reducer. With this amount of airflow 3" ducting is fine and can also use a wye (Y) adapter and have 2 intakes although using a 6" fan may be better for this.
This unit is perfect for a variety of duct cooling applications and is very aggressive while being extremely quiet. The motor utilizes a sealed ball bearing design with an estimated life span of 50,000 hours and an IP44 protection rating. This is an aggressive product that is ideal for removing hot air throughout a closet, room, or multiple enclosures.
Please Note:
* Noise ratings for these fans can be deceiving due to the fact that they are mounted 'remotely', this means it will not be installed in an area where noise from the fan really matters. What will matter more is that the fan is mounted properly so there's no noise from vibration and that ducting and a proper vent is used as those factors would create noise before one would typically hear the noise from the fan itself. Also testing procedures vary so this is also a very unreliable measure when comparing fans.
- 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.
General Information on Duct Fans
Due to the trend of addressing cooling and venting earlier in projects, during construction and when renovating, Cool Components has greatly expanded the 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 are typically installed 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).
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 (linear) 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.
