Our 2400 Water Fountain Aerator is an environmentally friendly oil-filled motor with a hard-face internal mechanical seal and external lip seal for protection against leaks. Highly efficient - lower power consumption than competitive equipment makes it affordable in the long term as well as at the time of purchase - the F2400/VFX only draws 5.6 operating amps. Superior dependability in salt-water and other corrosive environments. Requires little maintenance - we recommend cleaning the stainless steel motor housing once or twice per year.
