Life expectancy of 6 years can be seen with proper installation and maintenance of the pump
Quiet operation allows the pump to run without disturbing the homeowner as can be the case with rotary vane units.
Designed to self-adjust when the pressure exceeds the rated value of the pump, the piston stroke will automatically shorten to reduce the strain on the pump. At the same time, power consumption of the pump will decrease to protect against possible increasing temperatures. This is a definite advantage as diffusers can start to become clogged without the homeowner being aware of it.
Self-cooling design draws cooler intake air over the coils reducing the temperature seen on the interior of the pump extending the life of the unit.
Easy maintenanceProviding maintenance on the pump is relatively easy with a completely oil-less design and no need for additional lubrication. Along with changing the filter as required, the only component to replace in the pump afte an extensive operating period is the piston.
MEDO pumps feature a unique, patent-awarded linear-motor-driven free piston system that is globally proven in the wastewater treatment and aquaculture industries. This unique design theory eliminates the wear components typically found in conventional air compressors and vacuum pumps, such as crank shafts, connecting rods and ball bearings. The only moving part is the piston! Also eliminated is the need for any lubrication. Fewer parts translate into fewer problems.
A silicone diode between the coils converts the alternating current sine wave into a half-rectified input. The result is a pulsating electro-magnetic field energizing the resonant spring-mass (piston). When the electro-magnet is energized, the intake stroke of the piston compresses the return spring and draws air into the cylinder through the inlet valve in the head of the piston. When the electro-magnet is de-energized, the spring releases and the compression stroke of the piston forces the compressed air out of the cylinder through the reed style outlet valve.
