Airspace – aft seal General description • 4-ring aft sterntube seal system with a dedicated air chamber ensuring the perfect separation of sea water and sterntube lube oil • Excellent long term performance, high operational reliability and explicitly pollution free • Certified “Non Pollution” sterntube seal by all major classification societies • Known to the market since The seal rings are an integral part of the stern tube seal, which is a multi-barrier, lip-type seal. The seal rings are made of flexible rubber that can adapt to the movement of the shaft whilst ensuring an effective, reliable and long life seal. They are fitted in a seal housing and act against a rotating seal liner fixed to the shaft. They act as an effective seal whenever the pressure on. The two seal rings face the stern tube towards the oil, providing an active double security against oil spills. The other two seal rings face towards the seawater to effectively seal against seawater and sediments. The pressurised air in the central void space is dynamically controlled and monitored, based on the variations of the seawater pressure, which keeps the Wärtsilä Airguard system.
