Pond Aerator Bubbler | AerMaster Pro XL 1.5 HP | Bottom Diffused

 Aeration System for Ponds & Lakes up to 10 Acres

The AerMaster Pro XL 1.5 HP Pond Aerator is a commercial-grade bottom-diffused pond aeration system engineered to deliver maximum oxygen transfer and complete water circulation for large ponds and lakes up to 10 acres. Built for demanding applications, this powerful system restores and maintains healthy water by increasing dissolved oxygen, eliminating stagnant zones, and improving overall water quality from the bottom up.

Powered by dual 3/4 HP Quantum™ oil-less rocking piston compressors, the AerMaster Pro XL generates exceptional airflow to circulate the entire water column—even in large, deep bodies of water. This continuous circulation helps reduce algae blooms, minimize organic muck buildup, eliminate foul odors, and create healthier conditions for fish, beneficial bacteria, and aquatic plants.

Designed for ponds ranging from 6 to 10 acres, the Pro XL Series is the ideal solution for large residential properties, farm ponds, golf courses, commercial water features, recreational lakes, HOA communities, parks, and fisheries where dependable, high-capacity aeration is essential.

Despite its impressive power, the AerMaster Pro XL is engineered for quiet, energy-efficient operation with low-maintenance oil-less compressors and durable components built to withstand year-round outdoor use. The heavy-duty cabinet and advanced cooling system help ensure reliable performance season after season.

Whether you're restoring a large pond or maintaining a healthy aquatic ecosystem, the AerMaster Pro XL 1.5 HP Bottom Diffused Aeration System delivers professional-grade performance, superior oxygenation, and long-lasting reliability for cleaner, clearer, and healthier water.
