SweetwaterŽ Rotary Vane Compressors, 1/4 to 1 hp
The only compressor made specifically for the aquatic industry.
Sweetwater® motor-mounted, oilless rotary vane compressors are compact, easy-to-service and excellent for moderate-pressure, continuous-duty applications. They more than double the air output of piston compressors with better longevity. Sacrificial oilless carbon vanes automatically adjust as they wear to maintain efficiency.
Thermal overload protection, air filter, inlet check valve and 8' power cord is included. Ten-psi models work to a depth of 18 feet and 15-psi models work to 27 feet, depending on tubing diameter and distance.
The only wearing parts are carbon vanes, which can be replaced in about 15 minutes using common tools (in continuous operation, vanes last 9 to 18 months, depending on operating pressure).
All Sweetwater® rotary vane compressors are performance tested and covered by a one-year warranty (not including air filters, vanes, water damage or lightning damage). Single-phase models are 115V if not specified; three-phase are 230V. Check valves are recommended where long underwater runs of air tubing can fill with water when the compressor is off.
Three-phase models ship with vanes removed.
We highly recommend using protective devices with all 3-phase equipment. Motor starters, phase monitors and phase protectors are not included in the sale and should be sourced locally. Failure to install protective devices will void most warranties. We also recommend that a certified electrician perform the installation.
