FujiMAC Air Pumps

FujiMAC Air Pumps

FujiMAC Air Pumps are oilless diaphragm air pumps designed for reliable wastewater treatment, delivering stable, smooth airflow with efficient performance. They suit anyone who wants a quiet, energy-efficient, long-lasting pump that can be rebuilt in about 15 minutes instead of being replaced, and they are made entirely in Japan.

Key Benefits

• Built to last: the manufacturer describes it as the most quiet and energy-efficient diaphragm air pump, and also the most rugged and longest lasting.
• Compact: high-quality Japanese internal components, including a small, powerful rare earth magnet, make the pump smaller than competing pumps.
• Oilless design: a floating rare earth magnet and two proprietary synthetic diaphragms are the only moving parts, so there are no pistons, bearings or other wear items.
• Built-in safety switch: every pump has a reliable, resettable electrical circuit breaker. It interrupts power if a diaphragm fails, which prevents internal damage and allows a simple, quick rebuild rather than a full pump replacement.
• Easy maintenance: a rebuild takes approximately 15 minutes with two common hand tools, and sets the pump up for years of more reliable service.
• Stable airflow: performance does not degrade over time, which supports dependable wastewater treatment. Airflow is smooth and even, without uneven air pulses.
• Easy to stock spares: the pumps come in two physical sizes, and the models in the range share many internal parts.
• Simple model naming: the model number shows the pump's air production in litres per minute.

Made in Japan

FujiMAC has a 30-year track record of producing diaphragm air pumps, achieved through stringent quality control. Design, production and testing are all performed in Japan, and the manufacturer states that FujiMAC is the only wastewater diaphragm air pump available that is made in Japan.

Suitable For

• Wastewater treatment applications that need a steady, pulse-free air supply.
• Users who want a pump that can be serviced and rebuilt on site rather than thrown away after a diaphragm failure.
• Setups where low noise matters: noise levels range from 35 dB on the smallest models to 50 dB on the largest.

Compatibility

• All models are rated for 230-240 V.
• Models 40 R, 60 R, 80 R and 100 R have a 13 mm (0.5") outlet with an 18 mm (0.7") external diameter.
• Models 120 R, 150 R, 200 R, 250 R and 300 R have a 20 mm (0.8") outlet with a 26 mm (1.0") external diameter.

Frequently Asked Questions

How do I tell what each model delivers?
The model number is the pump's air production in litres per minute. For example, the 40 R produces 40 L/min and the 300 R produces 300 L/min.

How long does it take to rebuild a FujiMAC pump?
Approximately 15 minutes, using two common hand tools. The pump is designed to be rebuilt rather than replaced.

What does the built-in safety switch do?
It is a resettable electrical circuit breaker. If a diaphragm fails, it cuts power to the pump to prevent internal damage, so a simple rebuild is all that is needed.

How loud are these pumps?
Noise levels range from 35 dB on the 40 R and 60 R to 50 dB on the 300 R. The 80 R is rated at 36 dB, the 100 R and 120 R at 39 dB, the 150 R at 41 dB, the 200 R at 43 dB and the 250 R at 48 dB.

Do all models use the same outlet size?
No. The 40 R to 100 R have a 13 mm (0.5") outlet with an 18 mm (0.7") external diameter. The 120 R to 300 R have a 20 mm (0.8") outlet with a 26 mm (1.0") external diameter.

How heavy are the pumps?
The pumps come in two physical sizes. The 40 R to 120 R weigh 5.0 kg (11 lb), and the 150 R to 300 R weigh 9.0 kg (19.8 lb).
