Medo Linear Piston Air Pumps

These are not linear "diaphragm," but true linear "piston" type pumps. Since the only moving part—the piston—floats on a bed of air, a exceptionally long service life can be expected (8 years of continuous life is not uncommon). You will experience exceptionally quiet, energy-efficient operation and clean, oil-free air. An outdoor-rated housing, a grounded power cord, 3/4" hose barb and 115V/60 Hz are all standard ("H" at the end of the part number designates 230V/50 Hz). UL-listed. One-year warranty.

  • Extremely quiet.
  • Outdoor-rated housing.
  • True linear piston.
  • Exceptionally long service life.
  • Outstanding energy efficiency.

Note: To power any linear air pumps with inverters (square wave), oversize the inverter at least 200%.
