Do you have a plan for a cold room, or how do you ventilate a cold room? Will a 110 CFM fan fit into a smaller CFM housing?
Answer:
Quite often the fan will fit the smaller housing but even if it doesn't, these things are not hard to replace. If the cold room less than 50 sq. ft. of floor space, you might try: Cold room should be fitted with four-inch ducts leading from the present holes in the upper walls to within six inches of the floor. These ducts should be fitted with appropriate dampers to control temperature in there.
