Medo LA-120 Piston Air Pump
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
