A Q U A C U L T U R E A P P L I C A T I O N S

Consider the value of Medo’s new LA-80B:blower:

IT RUNS QUIETER, having about as much ambient noise as a

light ballast.

IT CONSUMES LESS ENERGY, having only 50-60% of the line

current requirements of diaphragm pumps.

IT LASTS LONGER, especially in hot, humid environments.

Look closely at the LA-80B and you’ll see a sleek, die-cast aluminum

housing. Within you’ll find a pair of specially treated 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.

For over three decades, Medo USA has been

designing, developing, engineering, and continu-

ously improving high quality air blowers for

challenging applications like wastewater and

aquaculture systems. The result is an intelligent package that runs

quieter, consumes less energy, and lasts longer than comparable

blowers for these applications.

Medo’s unique linear free piston design has one moving part per

cylinder – one. This enables Medo blowers to be smaller and lighter

than conventional aerators (e.g., diaphragm pumps), allowing

designers greater flexibility in system design. The compact

integrated design is also self-cooling, free of lubrication, and

self-adjusting for pressure spikes – automatically adjusting power

consumption and guarding against potential temperature overloads.

O P E R A T I N G P R I N C I P L E

A silicon diode between the coils converts

the full-wave input current into half-rectified

current. The result is a resonant spring-mass

assembly, energized by a pulsating magnetic field.

aquaculture and onsite wastewater systems.
