Sweetwater Remote-Drive Regenerative blowers are just as reliable as Sweetwater motor-mounted electric blowers, and they offer the added benefits of variable performance and drive devices. They are designed to be bolted to a base and driven by belts. The power source can be an electric motor, gasoline engine, diesel engine or even hydro power. They are perfect for use in electrical emergencies or anywhere electric power is not available. Engine-driven blowers allow the user to vary performance by simply changing the engine speed or the pulley size. Inlet air filters and double groove blower pulleys (sheaves) are included. Rotation is clockwise as you face the blower shaft. One year warranty. Made in USA.

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.

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.

NEW FOR 2017: Inlet Kits, Outlet Kits and Power Cords are now optional and sold separately.

Blower 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.
