There are so many things to love about the Kasco Marine Model 3400 3/4 HP Water Fountain Aerator, we wonder where to even begin! This floating water aerator can operate in as little as 17.5 inches of water. It includes 5 different interchangeable nozzles to create 5 different fountain patterns, and will bring magic to any backyard. That's like getting five fountains in one! It has the strength of an industrial fountain, meets the UL and CSA Standards for safety in water, and has been proven to have a higher water flow rate than the competition. Using low RPM technology, this 3/4 HP motor operates highly efficiently. This means lower operating costs, longer life for the seals and bearings, and less clogging. The motor is housed in a stainless steel can that is filled with environmentally friendly oil for excellent heat dissipation. All exposed metal is stainless steel. Minimal maintenance includes cleaning the stainless steel housing and removing clogs. All Kasco products are ETL approved to UL and CSA standards as complete packages for safety in water. Order with or without the optional lighting package to enjoy fantastic views. All of this ships fully assembled with a 2 year manufacturer's warrantee.
