Sweetwater® Regenerative Blowers & Parts
All models will operate on both 50 and 60 cycle (Hz). At 50 Hz, both pressure and volume will be about 30 percent less than the 60 HZ.
Please note the S41, S45, and S51 all ship oversize. Please inquire for a shipping quote.
3 Phase Note: Combination starters are not included, but strongly recommended. Local electrical codes prevail. 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. Ordering Information: Single phase blowers up to and including one hp are supplied with a power cord. To order 230V, add 230 after the part number, otherwise 115V will be shipped. All Sweetwater blowers come with inlet air filters and flexible pipe connectors as standard equipment. Three-year guarantee begins on date of shipment.
Inlet Kits, Outlet Kits and Power Cords are optional and are sold separately.

The blower has 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. The aluminum blower housing, impeller, and cover make major components inherently corrosion resistant promoting extended product life. High altitude will affect blower performance; deduct 4% of volume and pressure for every 1,000' (300 m) above sea level. The 3,450-rpm motors used on these regenerative blowers require about ten seconds to reach full speed. Use starting watts to size generators and use full load amps to size breakers.
UL-, CSA- and CE-compliant, direct-drive, TEFC motors feature permanently sealed ball bearings for increased protection against weather, dirt and moisture, particularly in a humid aquaculture environment. These high-efficiency type motors will run cool and handle a wide range of power variations so often found in rural locations. Permanently sealed bearings incorporate polyurea grease which extends bearing life and offers superior resistance to washout, rust and corrosion. Thermal over load protection protects motor windings from damage should the blower become stalled during operation. Additionally, thermal over load protection switches automatically reset when single-phase motor windings cool down to a safe level of operation.
Optional Inlet and Outlet Kits
Inlet filter kit features low- restriction, washable air filters, PVC elbow and pipe. Outlet kit includes flexible hose simplifying installation, stainless steel clamps and galvanized or PVC nipple. Kits sold separately.
Optional Power Cords
115V and 230V, 8' 14/3 gauge, 3-prong power cords sold separately (115V cord installed on models S31-A and S41-A).
- Oil-less operation ensures discharge air remains free of contamination
- Very few moving parts and no wear parts minimize downtime and lessen operating noise levels
- Mounts in any plane providing flexibility when mounting/integrating the blower into a system
- Simple to maintain - wash the inlet air filters as needed and replace the motor bearings after three years of continuous operation
