Norweco 206C Aerator

Norweco 206C Aerator Specs, Troubleshooting, and Ohio Replacement Notes

The Norweco 206C aerator is a Singulair mechanical aerator used to provide oxygen and mixing in the aerobic treatment chamber. When it stops, treatment quality can drop, odor can increase, filters can load faster, and downstream spray, drip, NPDES, or soil absorption components can suffer.

The aerator keeps treatment alive It is not a generic bubbler. Oxygen transfer, mixing, motor operation, current draw, and approval details all matter.

Quick homeowner answer

The 206C is listed by Norweco's product registration system as a Singulair aerator. Norweco registration language for the Singulair aerator family identifies an enclosed split-phase motor rated at 1/6 horsepower, 1725 RPM, 115 volt single phase 60 cycle power, about 4 amps during operation, and 3 cubic feet per minute of air delivery. In Ohio, confirm the exact model in the permit, as-built, service record, and local approval before substituting parts.

Manufacturer aerator specs and output profile

The 206C page should not feel like a generic alarm page. Norweco's registration listing gives the hard aerator specs: motor style, horsepower, RPM, voltage, operating amperage, and air delivery. Norweco's Singulair Model 960 page also identifies the fractional horsepower aerator as the only mechanical component and notes a certified 30 minute per hour run-time context for the Singulair system.

Field206C / Singulair aerator dataWhy it matters on site
ComponentMechanical Singulair aeratorProvides mixing and oxygen transfer inside the aerobic treatment chamber.
Motor typeEnclosed split-phase motorReplacement should match the approved aerator type, not only the opening size.
Horsepower1/6 HPDo not compare only against aftermarket horsepower claims.
Speed1725 RPMMotor speed affects the aerator's intended mixing and air-delivery behavior.
Power115 volt single phase 60 cycleControls, current sensing, breaker, receptacle, and wiring all need to match.
Current drawAbout 4 amps during operationUseful for service checks when separating motor failure from control failure.
Air delivery3 cubic feet per minuteAir delivery and mixing are the performance facts, not just whether the motor makes noise.
Run-time context30 minutes per hour on Singulair Model 960 certification languageConfirms control timing matters as much as replacing the physical aerator.
Air delivery point3 CFM listed

Use this with current draw and physical inspection. Noise alone does not prove the aerator is moving the expected air.

Motor point1725 RPM and about 4 amps

These are the service values that help separate motor failure from control, wiring, or timer problems.

Run-time context30 minutes per hour on Singulair Model 960 language

The control cycle matters. A correct aerator on the wrong control behavior can still create treatment trouble.

A working-looking aerator can still need service if the aspirator shaft, aspirator tip, control timing, amperage, or air delivery is wrong. A replacement should be matched against the approved Norweco system model and local Ohio file before it is treated as equivalent.

Why a Singulair aerator is not a generic air pump

A shaft-style Singulair aerator supplies oxygen and creates mechanical mixing in the chamber. A cheaper remote air pump and diffuser may make bubbles, but that does not prove it matches the approved mixing pattern, solids behavior, treatment performance, alarm logic, or Ohio approval. Treat replacement as a compliance decision, not only a price decision.

Symptoms that point toward aerator trouble

Common warning signs
  • Alarm light or audible alarm at the control panel.
  • Aerator not running during the expected cycle.
  • Strong sewage odor around the tank.
  • Dark or septic-looking effluent.
  • Fast Bio-Kinetic filter clogging or solids carryover.
  • Unusual vibration, grinding, squealing, or breaker trips.
What to document
  • Model number, serial number, system model, and service tag.
  • Alarm history and whether telemetry or Service Pro is connected.
  • Any odor, power outage, heavy water use, or recent pump-out.
  • Photos of the control panel, tank access, and aerator label.

Troubleshooting logic

1Confirm safe power statusCheck only safe exterior controls. Do not reach into the tank or wet electrical areas.
2Separate motor from control issuesAn alarm can come from current sensing, time clock, wiring, receptacle, breaker, or motor failure.
3Check treatment conditionOdor, solids carryover, filter clogging, and dark effluent can show the chamber has lost oxygen or mixing.
4Verify the approved modelBefore ordering, compare 206C against the system tag, design, ODH approval, and local health district file.

Maintenance tips

  • Keep the aerator powered unless a service provider instructs otherwise.
  • Keep the access cover clear and do not bury it in mulch, soil, snow, or landscaping.
  • Ask for current draw, air delivery, aspirator shaft condition, and aspirator tip cleaning to be documented.
  • Avoid grease, solvents, disinfectants, paint, harsh cleaners, and large chemical loads.
  • Keep replacement invoices and service records with the property file.

Frequently asked questions

What does the Norweco 206C aerator do?

It provides oxygen and mixing in the Singulair aeration chamber so aerobic bacteria can treat wastewater.

Is the 206C aerator the same as an air pump?

No. It is a mechanical shaft-style aerator, not simply an external air pump. A different air source can affect treatment performance and approval.

Can I use a cheaper replacement aerator?

Only if it is approved for the exact system and accepted by the local health district where required. In Ohio, treatment train approval matters.
