The Aermaster Surge 75 3/4HP Pond Aerator is engineered for large ponds and lakes up to 4 acres that require maximum oxygen delivery and complete water column circulation. Powered by a 3/4HP OWS Quantum™ rocking piston compressor-this model delivers a ton of airflow, ensuring massive surface areas and deep zones stay healthy, clear, and oxygen-rich. It combats algae blooms, prevents stagnation, and supports robust aquatic life. The oil-free compressor runs cool and clean, minimizing service intervals, while the powder-coated aluminum cabinet with dual cooling fans ensures year-round reliability and rust-free performance. 

Each AerMaster Surge Kit 75 includes the compressor, latching cabinet, pressure gauge, relief valve, self-cleaning Optimal Air™ diffusers, and 100ft of 1/2" Weighted Airline per diffuser selection. With both 115v and 230v options, installation is simple, requiring only basic tools. For those who need even quieter and weatherproof performance, choose our exclusive Pond Aerator Sound Kit or additional 1/2" Weighted Airline at checkout. Backed by a 3-year compressor warranty, 5-year diffuser warranty, and lifetime cabinet guarantee, the AerMaster is built for long-term water health and peace of mind.
