Maximum Aeration Power for Ponds and Lakes Up to 8 Acres
The ProLake™ 4 Sub-Surface Aeration System (Model PL-4CAB) is ProLake’s most powerful multi-compressor system, designed to deliver unmatched oxygenation across expansive ponds and lakes up to 8 acres in size. Featuring four 1/2 HP oil-free rocking piston compressors, this system drives high volumes of air through weighted tubing to multiple Duraplate™ self-cleaning diffusers—ensuring deep, even aeration from the bottom up.
Engineered for high-performance environments, the PL-4CAB comes housed in a rugged, weatherproof aluminum cabinet with advanced cooling and noise-dampening features. It’s the ideal choice for large estates, fisheries, municipalities, or commercial water management applications.

Benefits:
