The Wärtsilä Airguard is an anti-pollution lip type seal, which is especially designed for applications where extra security against the leakage of oil into the seawater is required.
The Wartsila Airguard completely separates the stern tube oil and the seawater by an air barrier. Any seawater and/or oil entering the air barrier chamber is automatically drained inboard without leaking outboard or entering the stern tube.
Wärtsilä Airguard takes away successfully the oil-to-sea- interface, it can be operated with mineral oil with regards to the US VGP2013. The seal is available for any shaft size between 450 and 1250 mm. Installation is easy, and the seal can be retrofitted to almost any stern tube.
