Aeration For Koi Ponds » Medo Air Pumps

The Linear-motor-driven Free Piston System on all the Medo Air Pump range has an internal piston inside the cylinder which is driven by an electro-magnet and spring system controlled by the alternating input current cycle.

The Medo air pump piston thus forms a single combined structure of two usually different devices; motor and pump.

Medo Air Pump's operating system is quiet and vibration free, and offers the advantages of easy maintenance and a long operating life.
