Ideal for liquid mixing(i.e., bubbling) and smaller aquaculture applications, Medo LA-45C is a low noise, energy-efficient, easy-to maintain aerator that needs no lubrication SPECIFICATIONS Model LA-45C Power Supply AC 120V. Rated Frequency 60Hz. Operating Pressure Range 0.71 - 2.13 psig. Rated Pressure 0.11kgf/cm2(1.56 psig). Rated Airflow* 45 LPM (1.59 cfm) or over. Power Consumption 45 W @ 60 Hz. Running Current 1.0 amps. Operating Noise 38 dB Max. Weight 3.0 kg. Highly reliable, unique, die cast piston construction. UL-approved for outdoor use. Integrated grounded line cord. Service life expectancy of 6 years with proper installation and periodic maintenance. Environmentally conscious design allows the pump to operate with lower energy consumption as it requres only 50-60% of the line currrent typically used by diaphragm pumps. UL-listed for outdoor use Low Noise Level The pumps operate at a very low noise level, about that of a light ballast, as there are no crankshafts, connecting rods or ball bearings to create additional noise. Low power consumption With the piston as the only moving part, frictional losses are diminished which allows for lower starting and running current. Line current requirements are only 50-60% of that typically used by diaphragm pumps. Automatic Pressure Adjustment Designed to self-adjust should the pressure exceed 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 Self-cooling design Air drawn in through the intake valve over the coils reduces the temperature seen in the interior of the 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.
