The answer is simple. Our dock circulators use maintenance free stainless steel, water cooled, and water lubricated continuous duty motors. Many of our competitors use an oil filled aluminum motor requiring expensive regular maintenance. Theirs require regular oil, seal and anode changes. Ours is maintenance free.

Competitor propellers typically are flexible nylon that break easily, while ours use a proprietary composite that has been impact tested while running to withstand most conditions without any failure.

Arbrux dock circulators also have a stainless steel motor mount protective structure around the propeller to prevent power cable damage while allowing leaves and other small debris to pass through. Arbrux dock circulators come with a power cable that remains flexible in freezing conditions so it easier to handle and provides years of reliable service.
