Sentinel® Commercial aeration systems are for large lakes and ponds where multiple aeration stations are required to provide adequate circulation and mixing in large bodies of water.
Sentinel® Commercial are availablle with either rotary vane air compressors or rocking-piston air compressors. The rotary vane systems provide more airflow and less pressure and so should be used in ponds and lakes no deeper than 16' deep; typical operation is in depths from 6' The piston air-compressor systems can be used in deeper ponds anywhere from 15' to 50' deep.
All cabinets are mounted on an equipment pad and include free noise-reduction insulation kit for reduced noise at no additional cost.
Airline is sold separately.

Airline is sold separately. Use 1/2" or 5/8" weighted airline in ponds and lakes. On shore use heavy-duty poly-pipe (1/2" or 5/8") suitable for burial.
Replacement rotary vanes, piston-rebuild kits, air filters and diffuser discs are all available as replacement parts.
1 Year Limited Warranty on Compressor (sacrificial vanes and piston seals excluded as excessive wear due to improper depth placement of diffuser can cause premature wear)
5 Year Limited Warranty on Cabinet & Diffusers.
