Frequently Asked Questions
What is the difference between the Gemini GC126 and GC128?
The Loren Cook Gemini GC126 and GC128 both run a two-speed motor. Cook designates the GC126 as the low speed model, wired to the red motor lead, and the GC128 as the high speed model, wired to the black lead. A replacement should match the speed on the old fan’s model tag.
Can a Gemini GC126 or GC128 be converted to an inline fan?
A Loren Cook Gemini GC126 or GC128 converts from ceiling to inline mounting with Cook conversion kit 797181, which replaces the inlet end plate with an inline cover panel. Going the other way, from a GN inline fan to ceiling mounting, takes kit 797180.
