Pentair Aquatic Eco-Systems

Sweetwater Regenerative Blowers

The Pentair Aquatic Eco-Systems 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, the air they deliver is oil-free, and they are extremely energy-efficient and quiet!

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.

Motor
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 highefficiency 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. All models will operate on both 50 and 60 cycle (Hz) power except models S631-B and S651-B, which are 60 Hz only.

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 S11 A, S21-A, S31-A and S41-A).

Features:

  • 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
