    Quiet, critical grade muffler is mounted inside the unit to prevent injuries.
  • Small, compact, attractive
    Makes for an easy, eye appealing installation, as close as 18" away from a building.

Installation System

  • 1 ft (305 mm) flexible fuel line connector
    Absorbs any generator vibration when conneted to rigid pipe.
  • Direct-to-dirt composite mounting pad
    Complex lattice design prevents settling or sinking of the gernerator system.
  • Integral sediment trap
    Prevents particles and moisture from entering the fuel regulator and engine, prolonging engine life.
