This VEVOR pond aerator system is designed to improve dissolved oxygen and circulation for ponds and lakes up to 1–3 acres and up to 50 ft deep. It uses a 3/4 HP (550W) oil-free air compressor delivering up to 5.2 CFM for efficient, low-maintenance operation. The included weighted self-sinking tubing and diffuser plate help distribute air effectively to support healthier water quality and reduce sludge buildup. Adjustable airflow makes it easy to tune output for seasonal conditions. Built-in protections such as overheat protection and an anti-backflow valve help support long-term use.
