Maximize water quality and oxygen levels with the AerMaster Pro 3/4 HP Pond Aerator, a premium bottom-diffused pond aeration system engineered for large ponds and lakes up to 4 acres. Designed to deliver exceptional airflow and complete water circulation, this powerful system increases dissolved oxygen from the bottom up, creating a healthier aquatic environment for fish, beneficial bacteria, and aquatic plants.

Powered by the high-performance OWS Quantum™ 3/4 HP oil-less rocking piston compressor, the AerMaster Pro delivers the airflow needed to eliminate stagnant water, reduce algae blooms, minimize organic muck buildup, and improve overall water clarity—even in deeper ponds. By circulating the entire water column instead of only the surface, the system provides superior oxygen transfer where it's needed most.

The energy-efficient, oil-free compressor operates cleanly and requires minimal maintenance, while the powder-coated aluminum cabinet protects internal components from the elements. Dual high-capacity cooling fans keep the compressor running at optimal temperatures, extending equipment life and ensuring dependable year-round performance.
