    Description

    High Power Air Pump 140L per Min - 100W - 0.042 MPa

    Keep your pond, aquarium or fish farming system well-oxygenated with the High Power 100W Air Pump. Designed to deliver a powerful and consistent supply of air, this high-performance diaphragm air pump helps improve oxygen levels in the water, creating a healthier environment for fish and other aquatic life.

    With an impressive air output of 140 litres per minute (8400L/h), this pump is ideal for larger ponds, aquariums, fish farms, hydroponic systems and applications that require a high-volume air supply.

    Its oil-free design delivers clean air without oil contamination, while the durable rubber diaphragm and valves are designed for reliable, long-lasting operation. The finned aluminium casing helps dissipate heat, keeping the motor cooler during use.

    Why Choose This High Power Air Pump?

    • Powerful Air Output – Delivers up to 140 litres per minute (8400L/h) for effective water aeration.

    • Energy-Efficient 100W Motor – Provides a high-volume air supply while consuming just 100W of power.

    • Oil-Free Operation – Supplies clean, oil-free air, making it suitable for ponds, aquariums and fish farming systems.

    • 32-Port Air Manifold Included – Distributes air to multiple outlets, making it ideal for larger aeration setups.

    • Durable Rubber Diaphragm – Designed for reliable performance and long service life.

    • Low Noise Design – Engineered to help reduce operating noise.

    • Efficient Heat Dissipation – Finned aluminium casing helps keep the motor cooler during operation.

    • Versatile Applications – Suitable for ponds, aquariums, fish farms, hydroponics and compatible effluent aeration systems.

    • Fish Farms – Provides a high-volume air supply for fish farming and aquaculture aeration systems.

    • Aquariums and Holding Tanks – Supplies air to compatible air stones and aeration equipment.

    • Hydroponic Systems – Helps oxygenate nutrient solutions to support healthy plant root development.

    • Effluent Systems – Can assist with aeration in compatible wastewater treatment applications.

    • Multiple Air Stones – The included 32-port manifold allows air to be distributed across several outlets.

    • General Air Supply – Suitable for compatible inflation, dusting and light industrial applications.

    Good to Know

    For effective aeration, connect your air pump to suitable airline tubing and air stones to distribute air throughout your pond, aquarium or aeration system.

    The pump should be installed in a dry, well-ventilated area, protected from rain and water splashes. Ensure the air outlets, tubing and air stones are suitable for the pump's airflow and pressure.

    When operating multiple air stones, the airflow will be shared between the connected outlets, so the number of air stones you can effectively run will depend on their size and installation depth.

    Whether you're setting up a new fish farming system, upgrading your pond aeration or supplying air to multiple outlets, the High Power 100W 8400L/h Air Pump offers a powerful and practical solution for keeping air flowing.
