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.

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.
