These long lasting, continuous duty compressors offer slightly less depth capabilities than the diaphragm compressors but produce considerably more air. These medium pressure, oil-free compressors are excellent for pond and lake aeration and de-icing. The carbon vanes self adjust to maintain maximum operating depth. All units come with air filter, 7' power cord and a one year warranty. Air outlet assemblies are available with two, three, four or five valves, allowing one pump to supply up to to five air manifolds.
