Wärtsilä 10-Years Airguard seal

Building on proven Wärtsilä Airguard performance, the 10-Years Airguard Seal gives you a decade of operation without needing to replace seal rings. This leads to significant operational cost savings over the lifetime of the vessel – up to 59% compared to conventional seals. 

  • Wärtsilä Airguard works with compressed air, which is applied to the void space between the seal rings

  • Constant flow of air pressure into the void space is set higher than the seawater pressure, resulting in a small amount of air forced out into the seawater

  • Seawater or oil that infiltrates the void space is automatically drained inboard, preventing oil leaking outboard or seawater entering the stern tube

  • Significant operational cost savings over the lifetime of the vessel
