The FujiMAC 100R2 Alarm Septic Air Pump is a durable, linear diaphragm air pump engineered for consistent performance in residential and light commercial wastewater treatment applications. Commonly used as a direct replacement in many 750 and 1000 gallon systems, it is also suitable for larger setups using multiple pumps.
Standard in many aerobic treatment units
Ideal for systems requiring a 100 L/min rated output
Compatible with systems operating in the 2.1 – 3.1 PSI range
This model features oil-free operation for cleaner airflow and reduced maintenance needs. The built-in thermal overload protection helps prevent damage during abnormal operating conditions. Quiet operation keeps noise levels comparable to typical indoor ambient sound.
Routine maintenance may include diaphragm rebuilds after several years of operation. Rebuild kits are available to extend pump life. In some cases, internal wear or contamination may require a complete replacement.
