The battery backup solar pond aerator NightAir II™ is engineered for pond owners who want dependable aeration day and night—without relying on grid power. By pairing high solar input with substantial battery capacity, this system is designed to keep air moving through the water column for long daily run times, supporting healthier water conditions in ponds and small lakes.

Built as a turnkey package (with concrete needed to set the mounting pole), the NightAir II™ combines a high-output solar array, deep-cycle battery bank, and a quiet brushless piston compressor to deliver consistent airflow to bottom diffusers. This circulation helps reduce stratification and supports improved oxygen distribution—key factors in overall water quality management.
