Inside the Gemini 140 Series Sonebuster

The Gemini 140 uses a forward curved injection wheel inside a galvanized steel housing with an integral backdraft damper. The grille is high-impact styrene and the unit ships with a 6-inch outlet flange and adjustable mounting brackets.

The GC-140 and GN-140 are AMCA certified and rated for continuous duty up to 105°F. Order the GC-140 for a ceiling job and the GN-140 for an inline job.

Gemini 140 Sonebuster Parts and Replacement Options

Replacement parts are available for the Gemini 140 Sonebuster. We supply the Gemini grille 615196 and the forward curved Gemini wheel 615158, plus dampers and hardware for the GC-140 and GN-140. If you are not sure which part you need, check the model tag on the unit or use the Loren Cook serial number lookup to confirm it.

The original Gemini 140 motor is no longer made. As an authorized Loren Cook distributor, Heinlein can still source parts for units that are out of production, and we can fit you with a current replacement unit when a rebuild does not make sense. The Loren Cook Gemini GC146 and GC148 is the current ceiling and inline exhauster that replaces the 140 in most jobs. Call us at 773-774-8616 and we will match the part or the unit to what you have.

Gemini 140 Sonebuster FAQ

What is the difference between the GC-140 and the GN-140?

GC stands for the ceiling fan unit with a grille, and GN is the inline duct version without one. Both move 100 CFM from the same Gemini cabinet, and a ceiling-to-inline conversion kit lets you switch an installed unit between the two. Order the GC-140 for a ceiling job and the GN-140 for an inline job.

Can I still get a complete Gemini 140 unit?

The original Gemini 140 is no longer built as a complete unit. We can supply replacement parts for the one you have, or match you to a current Loren Cook bath fan such as the Gemini GC146 and GC148.

Model	Configuration	Airflow	Power
GC-140	Ceiling mounted	100 CFM	115V, 1 phase, 60 Hz
GN-140	Inline / ducted	100 CFM	115V, 1 phase, 60 Hz
