Every FujiMAC RII shares the same engineering
The nine models differ in airflow, power draw and noise — the design underneath is identical. Pick the airflow your treatment plant needs and the rest comes as standard.
- Oil-less, two moving parts. A floating rare-earth magnet and two synthetic diaphragms — no pistons, bearings or oil to wear out or foul the air.
- Built-in safety switch. A resettable breaker cuts power if a diaphragm fails, protecting the pump so it can be rebuilt rather than replaced.
- 15-minute service. Rebuilds need two common hand tools. Filters, diaphragm kits and full service kits are stocked here, and models share internal parts across the range.
- Stable, even airflow. Output doesn't degrade over time and isn't subject to uneven pulses — steady aeration for reliable treatment.
- Japanese build, tested individually. Cast-aluminium housing, assembly under continuous quality control, and every pump performance-tested before packing.
- Two-year warranty. 12 months as standard, free-extended to 24 months when registered within 30 days of purchase.
