The Vevor pond aerator pump is designed to improve oxygen circulation in ponds and lakes up to 3 acres and depths up to 50'. Its 3/4 HP oil-free compressor delivers up to 5.2 CFM for efficient deep-water aeration with low maintenance. The included 360° nano diffuser plate helps distribute fine bubbles for better dissolved oxygen transfer and more complete water circulation. A 100' weighted self-sinking hose, timer, and required accessories are included for a ready-to-run setup. Built-in overheat protection and an anti-backflow valve support safer long-term operation.
