The Diffuser Ring is a must-have for turboprop owners because it reduces the aeration of prop blades caused by exhaust fumes. The design that is usually used reflects the need to establish a balance between a hole-shot circumstance, when maximum thrust is required, and a top-speed situation, where the lowest drag is required. With a distinct viewpoint and a commitment to thinking beyond the box, Michigan Wheel s team of engineers creates and builds products that give really novel solutions and barriers to some of the most difficult challenges. The Diffuser Ring (9500-123) is a brilliant illustration of its commitment to delivering solutions for a broken industry. Key features: The prop ring stops the exhaust gases from aerating the prop blades. It is especially excellent for avoiding stone or wood impacts in tall grass and/or underbrush. The diffuser ring directs high-pressure engine exhaust away from the prop, resulting in a quieter engine, longer blade life, and more efficient power delivery.
