Compact, quiet, and functionally vibration free, the highly reliable Medo Linear-Piston Pump will enhance your system's performance and extend its operating life.
Medo aerators have about as much ambient noise as a light ballast, and consume very little energy. In an era where energy costs continue to rise dramatically, Medo air pumps have helped to drive down total costs of system ownership. Medo air pumps last longer, especially in hot, humid climates.
Medo's unique linear free piston design has one moving part per piston - one. Medo piston aerators have an expected service life of 6+ years. A closer look within the Medo die cast aluminum housing reveals a pair of specially Teflon® treated pistons with extruded, hardened, and honed cylinders driven by highly efficient coils. The Medo, unified, heat sinking aluminum construction enables a greater, quieter operating aerator life, year after year after year.
Medo Air Pump's linear-motor-driven free piston system 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 piston thus forms a single combined structure of two usually different devices; motor and pump. The system is quiet and vibration free, and offers the advantages of easy maintenance and a long operating life.
The overall water volume of the pond is a key factor in choosing an aerator. A rough estimate is that every 1000 gallons of water will need 40 liters of air per minute to sustain the appropriate dissolved oxyen level for koi.
Always install your pond aerator above the water level of the pond. This will prevent water from being siphoned back into the pump when it is turned off. It will protect you from the danger of water and electricity coming in contact with each other.
An outdoor-rated housing, a grounded power cord, hose barb and 115V/60 Hz are all standard.
