Will the FujiMAC 80R2 Fit My Septic System?

The FujiMAC 80RII, commonly referred to as the FujiMAC 80R2, is a 120V linear diaphragm air pump rated at 80 liters per minute (2.8 CFM). It is commonly used in residential aerobic treatment systems requiring an 80 LPM aerator.

Common applications include certain models from:

  • Aqua Aire / Aqua Safe
  • EnviroFlo
  • Fuji Clean USA 
  • Pro-Flo

The 80R2 may also be suitable as a replacement for other 80 LPM septic air pumps when the treatment system manufacturer permits an equivalent replacement.

Important: Do not select a replacement pump based only on the physical size of your existing aerator. Confirm the required airflow, operating pressure, voltage, and outlet connection for your septic system before ordering.

If you are unsure which pump you need, send us the model number or a photo of your existing air pump and we can help you identify the appropriate replacement.

Contact SepticStop if you have questions regarding warranty coverage before ordering.

Is the FujiMAC 80R2 the same as the FujiMAC 80RII?

Yes. FujiMAC identifies the model as the MAC80RII, with the Roman numeral II. It is commonly written and searched for as the FujiMAC 80R2.

Can the FujiMAC 80R2 replace another 80 LPM air pump?

It may be suitable for systems designed to use an 80 LPM aerator, but airflow alone should not be used to determine compatibility. Verify the required pressure, voltage, outlet connection, and treatment-system requirements before replacing the existing pump.

What systems use the FujiMAC 80R2?

Fuji Clean USA specifies the FujiMAC 80RII for several treatment-system models, including the CE5, CE7, and CEN5. It is also used in other compatible aerobic treatment applications requiring approximately 80 LPM of airflow.

How much electricity does the FujiMAC 80R2 use?

FujiMAC lists normal power consumption at approximately 51 watts. Because septic aerators normally operate continuously, an efficient pump can make a meaningful difference in long-term electrical consumption.

Can the FujiMAC 80R2 be rebuilt?

Yes. The FujiMAC RII series uses replaceable service components, including diaphragms. The correct rebuild parts should be selected for the specific FujiMAC model.

Can I replace my septic air pump myself?

Requirements vary by jurisdiction and septic system. The customer is responsible for ensuring that installation, service, or replacement complies with all applicable laws, regulations, permits, and manufacturer requirements. When required, use a qualified septic professional.
