Sweetwater® Regenerative Blowers

Are All Regenerative Blowers the Same? NO!
Sweetwater® regenerative blowers reach higher pressures, operate in more corrosive environments and operate at lower noise levels than industry standard commercial blowers. They are inexpensive to operate, and the air they deliver is oil-free. They are extremely energy-efficient and quiet.

Sweetwater® blowers are simple. And simplicity means reliability. They have only one moving part: a dynamically balanced impeller that is attached directly to the motor shaft. The rotating impeller doesn't touch a thing, so there's no wear, no vibration, no seals and no lubrication. Just wash the inlet air filters as needed and replace the motor bearings after three years of continuous operation.

All Sweetwater® blowers come with internal mufflers and low-restriction, washable inlet filters as standard equipment. Outlet flex hoses, which simplify installation, are also standard equipment.

The Sweetwater® blower's electric motor is a high-efficiency type motor that will run cool and handle a wide range of power variations so often found in rural locations.

Automatic thermal overload protection is standard (except S631). Should a power brownout occur and trip the motor, the Sweetwater® blower will restart automatically after cooling. Motors are completely enclosed and fan cooled for the highest reliability in a humid aquaculture environment. Each blower is assembled with antiseize compound, performance tested prior to shipment and guaranteed by Pentair AES for three years! All are UL-listed, CSA-certified and CE-compliant.

Altitude
High altitude will affect blower performance. Deduct 4% of volume and pressure for every 1,000' (300 m) above sea level.

Hz
All models will operate on both 50 and 60 cycle (Hz) power except S631 and S651, which are 60 Hz only. At 50 Hz, both pressure and volume will be about 30% less than the 60-Hz curves shown.

Starting
The 3,450-rpm motors used on these regenerative blowers require about ten seconds to reach full speed. During this period, power draw is much higher than normal. See specifications for both starting watts and running watts. Use starting watts to size generators and use full load amps to size breakers.

Additional Information
Single-phase blowers up to and including 1 hp (plus S313) are supplied with a 8' power cord. All Sweetwater® blowers come with inlet air filters and flexible pipe connectors as standard equipment. Three-year warranty begins on date of shipment. Double the pressure by using two blowers of the same size, with one blowing into the other. See the 2S41 example in the performance curve.

3-Phase Equipment
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.
