The XQP550 generator set is EU Stage V emission standard capable. A unique feature is the introduction of clutch fan drive technology where the fan no longer needs to run continually at full speed and power. This saves additional fuel, while lowering noise output; an ideal feature when operating at lower loads, in cooler temperatures and, most importantly, in evenings when noise levels are most noticeable.
