• Complies with the VGP and VIDA regulations
  • 24/7 condition monitoring
  • Zero emissions of oil
  • Compact and self-regulatory system

How it works

Due to the extra air barrier between the oil- and water-repellent lip seals, any leakage is immediately transported to the transparent drain tank. A periodically generated vacuum ensures that the drain channel remains clean. The ACU monitors the condition of the aft seal (SAA) and lets you know the status of the seal at any time. In this way you know immediately when the drain tank needs to be emptied and maintenance is required.


The Supreme Athmos complies with the VGP and VIDA regulations because the oil and water-repellent lip seals are separated by a constant air flow. The Supreme Athmos is available for shaft diameters from 116 to 1150 millimetres.

The Supreme Athmos is the most popular choice for larger yachts, cruise ships and ferries. The VGP/VIDA regulations are the main reason for shipping companies to retrofit their seal with a Supreme Athmos. You avoid the use of expensive bio-oils and can continue to sail in American waters with mineral oils. You will pollute the environment with oil if you don’t have a sealing solution that ensures zero emissions of oil.

Extra safety: Supreme SeaGuard Athmos®

For extra safety, you can combine the Supreme Athmos with the Supreme SeaGuard (SGA). The extra oil-repellent lip seal can be activated in the event of excessive oil leakage. In this way an unnecessary dry dock can be prevented and maintenance can be postponed safely.


The Supreme Athmos consists of high-quality bronze housing parts, an aft seal (SAA), a stainless steel liner and ACU. The aft seal has two water-repellent and one oil-repellent rubber (NBR or FKM) lip seal. The forward seal (STF) consists of two oil-repellent lip seals and is lubricated by a compact circulation tank.


Due to the modular design, you can customise the Supreme Athmos using a broad range of options. The most frequently chosen options for the Supreme Athmos are:

  • Hard metal liner coating (recommended)
  • FKM lip seals
  • Dirt barrier
  • Wire winders
