Fujimac

The FUJIMAC 300 KII is a powerful air pump for aerating large ponds and filter systems. With a specified air output of 300 liters per minute (18,000 liters per hour), this model delivers a large volume of air through a single pump. The pump was developed and manufactured in Japan and uses synthetic rubber (EPDM) diaphragms.

Aeration helps keep water moving and supplies air to, for example, air stones, aerated bottom drains, or a biological filter. The setup that best suits your pond depends on several factors, including water depth, the air distributors used, and resistance in the hoses. The FUJIMAC 300 KII has a specified operating pressure of 20 kPa (0.020 MPa) and an outlet with an inner diameter of 20 mm / outer diameter of 26 mm.

Key Features

• High air output: 300 l/min, or 18,000 l/hour.
• For larger aeration setups: suitable for ponds, bottom drains, and filter systems.
• EPDM diaphragms: replaceable parts for periodic maintenance.
• Automatic shut-off function: stops the pump if a diaphragm or the compression chamber is damaged.
• Noise level: rated at 50 dB for this model. aquaja.nl

Placement and Maintenance

Place the air pump in a dry, dust-free location above the water level, on a stable surface. Protect it from rain and splashing water. Ensure that air can flow freely: a kinked hose or clogged air stone can cause the pump to overheat. According to the manual, clean the air filter every three to four months and replace the air filter and diaphragms annually, or replace the diaphragms sooner if the air output decreases.

Specifications

The FUJIMAC 250 KII is a powerful pond air pump for installations that require a large volume of air. With a rated capacity of 250 litres per minute, equivalent to 15,000 litres per hour, this model is suitable for aerating large ponds, aerated bottom drains and biological filters. The pump was developed and manufactured in Japan.

The FUJIMAC uses synthetic rubber (EPDM) diaphragms. The design limits internal heat generation, which contributes to the durability of the diaphragms. The sturdy housing and replaceable maintenance parts make the pump suitable for pond installations that are in continuous use.

For ponds and filters

You can direct the airflow to multiple aeration points using a suitable hose or air distributor. Think of air stones in the pond, an aerated bottom drain or a moving filter bed. The amount of air that reaches each point depends on the water depth, the length and diameter of the hoses and the resistance of the air distributors used. When assembling the installation, take into account the working pressure of 20 kPa and the outlet of 20 mm internal diameter / 26 mm external diameter.

Placement and maintenance

Place the FUJIMAC 250 KII level on a stable, dry and dust-free location, protected from rain and splashing water. Place the pump above the water level to prevent water from flowing back through the air hose. Also ensure that the hoses are not kinked and the air stones remain clear, so that the pump can deliver air.

Clean the air filter every three to four months. The air filter and the diaphragms are replaceable; also check the diaphragms when the air output noticeably decreases. The pump has an automatic shut-off function that activates when a diaphragm or part of the compression chamber is damaged.

Specifications

The FUJIMAC 200 KII is a powerful air pump for aerating larger ponds and biological filters. The pump delivers 200 liters of air per minute, or 12,000 liters per hour. This allows you to supply air to, for example, air stones, an aerated bottom drain, or a moving filter bed.

The pump was developed and manufactured in Japan and operates with synthetic rubber (EPDM) diaphragms. The design limits internal heat generation. With a specified noise level of 43 dB, the 200 KII is also relatively quiet for an air pump with this capacity.

Application and connection

The FUJIMAC 200 KII has an operating pressure of 20 kPa and an outlet of 20 mm inner diameter / 26 mm outer diameter. You can direct the airflow to one or more aeration points with a suitable connection. The amount of air that reaches them depends on, among other things, on the water depth, hose length, and resistance of the air stones or distributor.

Placement and maintenance

Place the air pump level on a stable, dry, and dust-free location, protected from rain and splashing water. Place the pump above the water level, so that water cannot flow back through the air hose. Prevent kinked hoses and clogged air stones: the pump must be able to discharge its air freely.

Clean the air filter every three to four months and replace it annually. Replace the diaphragms annually or sooner if they are damaged or the air output decreases. In the event of damage to a diaphragm or the compression chamber, the automatic stop function turns off the pump.
