Evolution Aqua Airpump 150

Model: AirPump150

A mains-powered Evolution Aqua pond air pump (Airpump 150, AIRPUMP150). Manufacturer documentation provides multiple, conflicting numeric values for airflow, power and maximum operating depth—see limitations for details.

About Evolution Aqua Airpump 150

The Evolution Aqua Airpump 150 is a mains-powered pond air pump intended to provide high-volume aeration and to drive moving-bed / biological filter air supplies. Evolution Aqua’s own product pages and technical PDFs describe features relevant to installation and use: the unit is designed for permanent wiring, must be protected from the weather and must not be submerged. The manufacturer recommends using large-bore airline (8 mm or 10 mm) and, where the pump is mounted below the waterline, fitting a non-return valve and elevating the pump where practical. The Airpump 150 includes built-in thermal protection and a safety switch system that will shut the unit off if there is a fault with the diaphragm or electromagnet. Several useful technical items are stated consistently in Evolution Aqua documents: the pump’s weight (8.8 kg), rated pressure (0.18 kg/cm2) and an operating pressure range (0.1–0.25 kg/cm2), recommended ambient operating temperature (5 °C to 40 °C) and a factory warranty period of 2 years. However, Evolution Aqua’s own published files contain conflicting numeric values for airflow (litres per minute), electrical power and maximum operating depth. Because those manufacturer sources disagree, this entry does not attempt to reconcile the conflicting numbers—the conflicts are summarized in the limitations section and the original Evolution Aqua sources should be consulted for confirmation.

Best for

Higher-volume pond aeration and supplying air to moving-bed biological filters; Evolution Aqua filter documentation recommends this pump for certain filter/media volumes (examples in Nexus/filter materials reference).

Things to consider

Evolution Aqua’s own first-party documents contain conflicting numeric specifications for the Airpump 150: airflow is reported as 150 lpm (product page/brochure), 150 lpm (manual UK/EU) / 155 lpm (manual USA), and 100 lpm (dimensions/performance PDF). Maximum operating depth is reported as 5.5 m (product page/brochure), 5.1 m (manual UK/EU) and 15 ft (~4.57 m) for the USA variant. Power usage is reported as 106 W (product page/brochure), 112 W (manual UK/EU), 129 W (manual USA) and other watt figures (87–94 W) in the performance PDF. Because these are conflicting first-party values and no single authoritative value is identified in the supplied documents, the numeric fields for flow (L/h), max head (m) and power (W) are left null here. Cable length, IP rating, number of standard outlets and explicit pond-volume/fish/koi capacities are not stated in the supplied Evolution Aqua materials and are therefore null.

Installation

Follow the manufacturer manual: unit must not be submerged and should be weather-protected; intended for permanent wiring—connect via an RCD (≤ 30 mA) as recommended; install above pond level where possible and fit a non-return valve if mounted below waterline; use 8–10 mm internal-bore airline and appropriate manifolding for distribution.

Maintenance

Manufacturer documentation indicates built-in thermal protection and a safety switch; the supplied manual contains further maintenance and service guidance. No specific maintenance intervals or schedules are provided in the supplied documents.

Safety

Do not submerge the pump; protect from weather. Connect through an RCD with a tripping current of 30 mA or less as recommended by Evolution Aqua. The unit incorporates thermal protection and a safety switch; consult the manual for wiring and safety instructions.
