The Flagg-Air® 340HT-J Septic Aerator is a brand-new, not refurbished, shaft-style septic aerator with 12” brackets designed specifically for use in Jet®* tanks as a premium OEM replacement for ALL Jet® aerator units (including models 660, 665, and 700LL), Alpha Air AL500-12 model, and model 735.

The Flagg-Air® 340HT-J Septic Aerator features a low RPM with high CFM, fully enclosed continuous duty motor with 2-foot power cord; pre-lubricated and sealed bearings; and a 7-amp mini breaker. This shaft-style aerator has a 304 stainless-steel aerator shaft, bronze coupler, and powder-coated steel brackets that have rubber vibration restrictors to provide improved mounting stability and bearing life. The Flagg-Air® 340HT-J Septic Aerator uses only high-impact plastic for the suds restrictor, aspirator, and the 3-in-1 T-Bar handle.

The distinguishing difference between the 340HT Series Flagg-Air® aerators is bracket size. The FA340HT-J is a Jet® septic aerator replacement with 12-inch brackets designed to fit the 10” diameter tank opening in Jet® aerobic septic systems. The FA340HT-N is a Norweco Singulair® ** septic aerator alternative with 14-inch brackets designed to fit the 12” diameter tank opening of Norweco Singulair® aerobic septic systems. Jet® septic aerators will be red and Norweco Singulair® aerators will be blue. Measure your tank opening to determine which aerobic septic system pump replacement to buy or call our Customer Service at (800) 778-1540 for assistance.

Every Flagg-Air® septic aerator includes a separate 7-amp mini circuit breaker to protect the motor. Installation of this mini breaker is required for warranty purposes. If you are replacing a Flagg-Air® septic shaft aerator, it is recommended to replace an existing 7-amp breaker with the new one that was shipped with your unit.
