Dual Grille Bath Fan 230 CFM for 4" and 6" ducting, this fan system allows two points to be exhausted through a single opening in the roof or gable end of the house. The system is really quiet because the fan is located remotely from the grilles. The system comes with the fan, grilles, and ducting 'Y'. It only needs ducting, a exterior hood and switches.
Dual Grille Bath Fan
There are a lot of times when a single fan connected to two grilles is an advantageous idea. Two small bathrooms can be connected to a single fan with a single opening to the outside. One large bathroom might be better with two grilles spread out near the shower and near the toilet.
This kit includes a powerful in-line fan that can really haul the air through the ducting, a 'Y' ducting connector with one 6" opening toward the fan and two 4" openings toward the grilles, and two, un-lighted grilles and mounting housings that can be attached to the rafters. Because the fan is mounted remotely from the grilles, there is virtually no noise in the bathroom.
This system can be used very effectively with the Ventech Master and Auxiliary switches for control in each bathroom and continuous ventilation to building the ASHRAE 62.2 Standard embodied in many of the Green building programs and mandatory in California.
