Surface Mechanical Aerator

The Aqua-Jet aerator is a mechanical direct-drive unit designed to provide optimum oxygen transfer in a variety of municipal and industrial wastewater applications. The performance of the Aqua-Jet aerator also provides the mixing necessary to uniformly disperse oxygen and organic matter within the microbial population.

The robust design and use of the highest quality materials have also made the Aqua-Jet the most trusted aerator in the industry, outlasting other aerators 2 to 1.

How It Works

Basin water is pumped up into the intake cone and through the volute, and is dispersed through the diffusion head in a spray pattern.

Oxygenation occurs at two critical points:

  • When the water exits the diffusion head, and
  • When the spray enters the water surface

SAF-T Float® Technology

The SAF-T Float® Safe Accessible Float Technology is the result of customer feedback for a solution that provides service personnel with safer, easier and more accessible maintenance on Aqua-Jet® aerators and AquaDDM® mixers. This new technology encompasses two critical features: 1) a docking station each float that receives a set of lightweight, removal handrails and; 2) a non-skid coated surface onto the section of the float where the handrails attach, providing a safe grip for maintenance staff to stand on the float.

How It Works

Features & Specifications

  • Removal Handrail Design
  • Light Weight
  • Non-skid Surface on Float
  • Locking Pin Design
  • Indexing Slot for Positive Engagement
  • Retrofit Existing Units for Handrail Installation


  • Safe Access to Aerators and Mixers
  • Provides Maximum Worker Safety
  • Multi-Faceted, OSHA Compatible Security
  • Non-Compromising Performance
  • Easy Installation in Less than Five Minutes
