Robust-Aire™ Diffuser Systems use an onshore compressor to deliver air through weighted tubing to diffusers at the bottom of your pond. These systems are capable of aerating very large bodies of water affordably and are the least visible method of doing so. All Robust-Aire™ systems include a compressor, weighted tubing, barbed connector and adapter fittings, stainless steel tubing clamps, a power cord, and diffuser(s). Diffuser systems are available with or without a cabinet. Cabinets however are recommended since they include a cooling fan, acoustical foam, and a 120 volt receptacle.
