Greenheck’s model CUE direct drive upblast power roof ventilators now feature additional enhancements in sizes 060 to 160—a configurable curb cap makes it easy to replace an existing fan with no adapter if curb sizes don’t match, and a two-conduit option allows low-voltage and high-voltage wiring to be separated without field-fabricating another wiring conduit chase.

The model CUE ventilators are used in new or replacement fan installations in clean air, restaurants, emergency smoke control, light contaminants, seismic, and high wind and hurricane applications.
