The Ceiling Grid Vent System (VS-CGVS) from Cool Components is designed to aggressively vent air from equipment rooms or closets. The unit easily installs in a standard 2 x 2 ceiling grid and uses nine professional-grade 120mm DC fans to aggressively, but quietly, vent up to an impressive 575 CFM of air. The fans are automated by using two independent temperature controllers with the first turning on one bank of fans at 80F and the second controller turning the remaining fans on at 88F. This means that the fans only run when necessary which saves energy and increases the life of the system. The unit is constructed of lightweight aluminum and has an attractive white enamel finish. The grid face features concealed hinges that allow for easy cleaning and service if necessary.If noise is an issue, the fan speed can be adjusted to effectively lower fan noise. More advanced temperature controllers can also be used to automatically vary the speed of the fans or change the on and off set points if desired (available separately). While the unit can be customized, this package includes the Ceiling Grid Housing, Fan Panel with 9 Fans and 2 Basic Controllers installed, and 2 Power Supplies so the two banks of fans can be powered separately for redundancy and added versatility.
