IM-20 25-125 HP

Industry-Exclusive Design

The IM-20 was developed for the 25-125 HP blower market, with size and efficiency in mind. The low profile, vertical inlet, and small footprint make the IM-20 ideal for replacing less efficient blower technologies. The IM-20’s compact architecture allows it to fit through a standard 36-inch man door and be placed on most existing blower pads without modification. The vertical discharge and low profile simplify installation by allowing the IM-20 to be set in the same location as a previous blower with minimal piping modifications.
