The AerMaster Pro 1/2HP Pond Aerator is a high-capacity deep pond aeration system built for larger lakes and water bodies that demand maximum oxygen delivery. Featuring a powerful 1/2HP OWS Quantum™ rocking piston compressor, this system moves serious air for up to 2.5 acre ponds, allowing you to cover greater depths and larger surface areas with ease. It improves fish health, eliminates stagnant zones, and reduces algae blooms through full water column oxygenation. The rust-free, powder-coated aluminum cabinet includes dual cooling fans for reliable all-season operation, and the oil-free compressor ensures minimal maintenance. 

Each AerMaster Pro 1/2HP Kit includes the compressor, latching cabinet, pressure gauge, relief valve, self-cleaning Optimal Air™ diffusers, and 1/2" Weighted Airline. 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.
