Rotary Vane Compressors
The Pentair Aquatic Eco-Systems Sweetwater® motor-mounted, oilless vane compressors are compact, easy-to-service and excellent for moderate pressure, continuous-duty applications. They more than double the air output of reciprocating compressors and have 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 are included on single-phase units. Ten-psi models work to a water 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 9–18 months, depending on pressure. See related products for vanes and replacement parts.
Three-phase models ship with vanes removed. Three-phase compressors do not have a power cord and must be wired by an electrician. Pentair AES highly recommends using protective devices with all 3-phase equipment. Failure to install protective devices will void most warranties.
More Info
All vane compressors are equipped with an inlet muffler and 3/4" NPT ports. All compressors include 1,725 rpm ODP motor, except for Model AQ20 which does not include a motor. Model AQ20 can be powered by belts and pulleys. The AQ20 shaft is 7/8" diameter, 4.5" H and rotates counter clockwise (facing shaft). Operating range is 800–1,800 rpm.
All Sweetwater® compressors are performance tested before shipping and covered by a one-year warranty (not including air filters, vanes, water or lightning damage). Check valves are recommended where air tubing can fill with water when the compressor is off.
