Solatube® Add-On Kits FAQS

A typical bathroom fan will move about 50 cubic feet of air per minute (CFM). The proprietary fan / motor in the Solatube^® Ventilation Add-on Kit is rated at 110 CFM (3 cubic meters per minute), which means it is more than twice as effective at clearing air than a standard fan.

The Solatube® Daylighting System 160 DS is available with an attractive optional Solatube Ventilation Add-On Kit. When the Solatube 160 DS is combined with a Ventilation Add-On Kit and a Solatube Light Add-On Kit, it becomes an attractive 3-in-1 ceiling fixture.

• Quiet, remote in-line fan motor with opposing rotation to overcome pressure and increase speed and volume of airflow, even under extended duct runs
• Fan motor moves up to 110 cubic feet (3 cubic meters) per minute
• Optional Roof Vent Cap: Self-flashing design for easy installation. Gravity damper prevents back flow. Low profile in black color blends with roof.

Recommended for residential use only.

The Solatube® Ventilation Add-On Kit features an in-line fan motor assembly that is remotely mounted in the attic or plenum rather than on the ceiling of the room to be vented. This significantly reduces the noise level in the room below.

At this time, there are no sones (sound) level test standards available for this product due to the number of variables involved with its installation, such as:

• Type of duct
• Length of duct
• In-line fan motor assembly distance from intake source

However, it is generally accepted that remote-mounted venting is usually quieter than in-room venting.

Yes. The Solatube® Light and Ventilation Kits can be added to the Solatube Daylighting System 160 DS model to create a dynamic 3-in-1 fixture that includes daylighting, night lighting and venting functions in one ceiling location.

A minimum of 12 1/2 in. (318 mm) between ceiling joists and a minimum of 12 in. (304 mm) of vertical clearance above the ceiling is required in order to use the Ventilation Add-On Kit. It is also important to note that service access is required to the fan motor assembly junction box.
