"AF" (includes a float) models are high oxygen transfer models with no fountain display. All include two (or three) 50' braided nylon mooring ropes and are available with 50', 100', 150', or 200' SJTOW underwater rated electrical power cords.

Kasco Pond Aerator models include:
• Longer-life top and bottom ball bearings
• Environmentally friendly oil-filled motor with a hard-face internal mechanical seal and external lip seal for protection against leaks.
• Flood oil lubricated for excellent heat dissipation.
