Sourcingmap DC 6V Mini Air Pump Motor for Aquarium Tank Oxygen Circulate

At 5v this pumps a huge amount of air but, and this a very big BUT, it is so loud. Unbelievably loud. You could not use this as a replacement pump in your living space. I tested it at 3.3v to see if it would run a bit quiter but found that, even though it is still powerful, it is just as noisy as if using it at 5/6v. This led to the conclusion that it is not the motor but the diaphram system that is causing the noise. As an emergency pump, or if you are using it outside/in the shed, it is OK. However, if you want quiet this ain't the pump for you.

Firstly the delivery time for this product was fantastic however, when the pump came it had scratches on the metal case and the opening for the air seemed melted and worped. It appeared to me the pump had been used before. Little air was produced from the spout when felt on a wet finger but small bubbles could be produced when placed in water. The moters was also noisy.

Works perfectly

El producto llego en un estado deplorable. Sucio, con la etiqueta arañada y un aspecto desagradable. Parecía un producto viejo y usado.

Presa per realizzare un dispenser di bibite, funziona benissimo. Alimentare a 9v. Consegna rapida. Idonea per primi esperimenti con i più piccoli.

うちは金魚やメダカのためではなく子供の夏休みの自由研究の材料に使用しました。空気をペットボトルに送り込んだ圧力でジュースが出る仕組みでドリンクバーを作りました。持ちや耐久性は分かりませんがこれには良い感じ！ちゃんと出ましたよ！丁度良い空気圧！皆さんお試し下さい。

Comprato per un esperimento di mio figlio, arrivato rapidissimamente in meno di 24 ore ... funziona !Pacco enorme per un prodotto piccolino ma ben imballato
