The Aquarian Quantum 5 HP 230V Floating Surface Aerator is built for the most demanding water management challenges-municipal wastewater, industrial lagoons, stormwater retention, and high-load agricultural ponds. With a flow rate of up to 2,700 GPM and oxygen transfer up to 15 lbs O₂/HP/hr, it accelerates biological treatment, eliminates odor, and maintains dissolved oxygen levels even in extreme conditions. Engineered for reliability, the Quantum features a UL778-rated stainless steel Franklin Electric motor, water-cooled and water-lubricated for efficiency and long service life. A balanced 316 stainless steel propeller and hydraulically optimized diffuser maximize horizontal water movement for rapid oxygen dispersion. With over 95% of its mass submerged and a low-trajectory spray pattern, it stays upright and operational in ice, wind, and storms. Installation is straightforward with included mooring and electrical diagrams, and the sealed, corrosion-resistant design keeps maintenance to a minimum. Made in the USA and built to last, the Quantum is the no-compromise solution for systems where failure is not an option.

The Aquarian Commercial 2HP Floating Aerator (230V Single Phase) is built for the toughest water environments-municipal wastewater, agricultural lagoons, or stormwater retention. Delivering up to 1,700 GPM with 5.5 lbs O₂/HP/hr, it maximizes oxygen transfer to control algae, eliminate odors, and restore water quality. Its low-profile diffuser spreads water in a wide horizontal spray for maximum contact and minimal ice buildup. Powered by a UL-recognized Franklin Electric stainless steel motor-water-cooled and water-lubricated-it runs smooth and quiet for years. With over 95% of its weight submerged, it stays stable in high winds, waves, and freezing conditions. No belts, no external shafts-just dependable, low-maintenance operation.

The Aquarian Pro 1/2 HP-1.5 HP Floating Surface Aerator delivers professional-grade oxygen transfer for ponds and lagoons. Producing up to 2.3 lbs O₂ per HP per hour, it combats algae, eliminates odors, and prevents fish kills with powerful 500 GPM water movement. Its ice-proof, wind-proof design keeps 95% of the unit submerged, preventing capsizing and ensuring continuous operation even in freezing conditions.

Built in the USA, the water-cooled, water-lubricated stainless steel motor runs whisper-quiet and requires minimal maintenance. The balanced 316 stainless steel propeller and corrosion-resistant diffuser maximize efficiency and longevity. Installation is simple-mooring and electrical diagrams are included, and most users can install without professional help. Ideal for ponds up to 1 acre, this aerator is the perfect blend of performance, durability, and reliability.

The Classic Series 3/4 HP-5 HP Aerating Pond Fountain blends elegant water display with hardworking aeration to keep your pond healthy and beautiful. Designed for shallow ponds up to 5 acres, this commercial-grade fountain delivers a dramatic “V”-shaped spray up to 11 feet high while moving up to 1400 gallons per minute. The result-improved water circulation, higher oxygen levels, and reduced algae buildup. Built with a stainless steel, water-cooled motor and a UV-stabilized, “Never Sink” float, it’s engineered for year-round reliability. A foul-resistant propeller, corrosion-resistant materials, and pre-assembled plug-in design make installation quick and maintenance minimal.
