Airmax PS40 Pond Aeration System, 115V with 3 Diffusers and 300 ft Airline

The PS40 is a complete, scalable aeration system for larger ponds and small lakes. Three diffusers distribute air across multiple zones simultaneously, eliminating the oxygen stratification that occurs when a single-point system aerates a large water body. The kit ships with 300 ft (91 m) of 3/8" EasySet airline, providing enough run length to place the compressor well back from the water's edge.

Three-Zone Aeration for Larger Ponds

A single diffuser concentrates all aeration in one area, leaving the rest of the pond under-oxygenated. Three diffusers positioned across the pond depth and area circulate the entire water column, preventing thermal stratification and maintaining safe dissolved oxygen levels for fish throughout the season. The PS40 covers ponds up to 2 to 3 acres, depending on depth and fish load.

Installation

Mount the compressor in a sheltered, waterproof location above the ice line. Route airline from the compressor manifold to each of the three diffuser positions. Space diffusers evenly across the pond floor, prioritizing the deepest zones. Secure airline at intervals to prevent movement. Run continuously 24 hours a day for consistent oxygen delivery and maximum fish safety.

Ideal for farm ponds, stormwater features, recreational ponds, and small lakes from 1 to 3 acres requiring distributed, year-round dissolved oxygen management.
