Marine Diesel Engine Air Starting System

//TMY11QD Marine Diesel Engine Air Starter – Vane Type

TMY11QD Marine Diesel Engine Air Starter – Vane Type

The TMY11QD marine diesel engine air starters utilize the safe, reliable power of compressed air to generate initial rotational motion to start the diesel engines. Because they do not use elctrical power, and have robust, compact and lighter weight structure, they are commonly used in the hazardous environment where the atmosphere could be volatile, damp, or even explosive such as oil and gas drilling, shipbuilding, marine, vessels, and petrochemical industry. These marine diesel engine pneumatic starters are easy-operated, offering output power up to 30kW at 0.8 Mpa air pressure. In addition these air starters are fully customizable according to your actual needs. Simply talk to our engineers here and submit your request.

  • Max Rated Power: 30 kW (40.2 psi) at 0.8 Mpa (116 psi)

  • Air Consumption at Max. Power: 360 L/s

  • Working Pressure: 0.4 – 0.8 Mpa (58 – 116 psi)

  • Suitable for ATEX spark-resistant requirements.

  • Pre-engaged starting design get rid of any risk of sparks from the gear collision.

  • Fast and reliable high starqing torque with low air volume supply.

  • Cast Stainless Iron and sealed structure to prevent corrosion and abrasion.

  • Easy operation and little maintenance required, designed to be install-and-forget.
  • The TMY11QD vane air starter generates the highest output power at a comparably much lower speed of 1750 – 2180 rpm, and only requires a little amount of lubricating oil.
  • High starting torque is available with limited air volume supplied.
  • Air motor torque can be adjusted simply by changing the air inlet pressure and volume.
  • Air starter speed can be regulated through simple pneumatic valves instead of expensive and complicated electronic speed controls.
  • Have a check of the other pneumatic starter motors YS offers with different output power and drives here:
    TMY6QDTMY9QD, TMY 50QD (Turbine Air Starter), and TMW15QD (High Torque Air Turbine Starter).
  • NOTE: Operation of vane air motors with no load at high speed should be avoided.


  • Cast-Iron construction and top-grade material made components to resist corrosion and damage.
  • Pneumatic drive and non-aluminum design reduces the risk of explosion or sparks
    (ATEX Certified level Ex II 2GD c T5 IIB T100°C)
  • The pinion and ring gears are fully engaged before the rotation speed reaches high level that prevents the risk of sparks caused by gears collision.
