• 304L or 316L stainless steel
• All sizes have bottom flange for simple bolt-on attachment of the standard intake cone or optional anti-erosion assembly or draft tube
• Gussets at top and bottom flanges add strength

11. Volute

• 304L/316L stainless steel
• All sizes have bottom flange for simple bolt-on attachment of the standard intake cone or optional antierosion assembly or draft tube
• Gussets at top and bottom flanges add strength

12. Intake Cone

• 304L stainless steel
• Hydraulically designed for proper loading on propeller
• Sufficiently sturdy to support assembled aerator on hard, flat surface
• (Optional) Draft Tube for deep water depth application

13. Anti-erosion Assembly

• (Optional) for low-water depth application

When it comes to design, engineering, versatility and performance, the EcoJet™ aerator meets and exceeds the demands and standards of industrial and municipal wastewater treatment.

Offering a variety of standard aerator models and custom material combinations, the EcoJet™ aerator will help ensure maximum return on investment, cost-effective operations and efficient results.
