Kubota SQ GeneratorKubota Diesel Generators SQ Series

Kubota diesel generators SQ Series offers a super quiet generator, providing you with quiet, heavy duty 4-pole power.

Kubota Diesel Generators SQ Series Standard Features

  • The generator and the engine are direct-coupled to ensure a more reliable power supply with minimum power loss.
  • Solid-state voltage regulation maintains excellent stability (less than 5%) during changing load conditions. Quick response automatically provides stable power to sensitive equipment.
  • Diesel engines selected to power the heavy duty SQ series produce far less soot, HC and CO emissions thanks to Kubota's original E-TVCS combustion. All have passed the USA EPA Emission Tier 4i Regulation.
  • Noise within the generator unit is reduced through the use of a noise absorbing duct with 3 air intake holes.
  • The over-sized engine silencer helps reduced the sound level. A special two-stage engine silencer system is used in generators powered by V3300 to reduce noise even further.
  • Large diameter, slow speed fan is very quiet, yet maintains the same cooling effect as one running at normal speed.
  • A long air filter inlet hose is used to keep the low frequency noise down.
  • The SQ series is equipped with large capacity bottom mounted fuel tanks to prevent fuel spills inside the enclosure. The locking fuel cap is placed to avoid damage and simplify refueling.
  • The advanced design and superior engineering minimizes both space and weight. Transportability is improved with slots on each side of the machine for safe forklift truck transportation. Four tie down points and sturdy lifting eyes further enhance hoisting and transportation.
  • Single side maintenance – oil gauge, filter, oil replacement port, fuel filter, water reserve tank, battery and air filter are all located on one side for quick inspection and maintenance. Engine oil and coolant drain extensions are provided to ease regularly scheduled maintenance.
  • Locking control panel door shields the instrument panel from the elements and permits observation of all key functions without opening the door.
  • Every time the engine key is turned ON, air is automatically purged from the fuel system.
  • The fully covered load center houses all the outlets, compression terminals, and circuit breakers. To prevent inadvertent contact with the terminals, the receptacles are divided in a separate section.
  • Safety door interlocks automatically shut down the engine if the load center doors are opened during operation. For safe, unattended operation, even the maintenance doors are equipped with safety interlocks.
  • Large, removable doors feature heavy-duty steel hinges and recessed locking door latches safeguard against unauthorized use, allow safe, unattended operation and easy maintenance.
