PRIMAIR (Compact): the air regulated seal

Advanced Protection for Stern Tube Systems

The PRIMAIR (Compact) is an innovative air-regulated seal system designed to provide superior protection for stern tube systems. By creating an air chamber that physically separates stern tube oil from seawater, the PRIMAIR system eliminates the risk of cross-contamination. This cutting-edge seal is compliant with the Vessel General Permit (VGP) regulations, even when using conventional lubricants, making it an ideal solution for environmentally conscious operations.

  • Air Chamber Separation: Stern tube oil is physically isolated from seawater by an air chamber, ensuring no cross-contamination occurs.
  • Reduced Wear: The innovative design significantly reduces wear on the seal ring and liner, extending the lifespan of key components and reducing maintenance costs.
  • VGP Compliance: Fully compliant with VGP regulations, even when using conventional lubricants, making it a versatile solution for various vessels.
  • Real-Time Data Logging: Provides real-time monitoring of the seal’s performance, allowing for proactive maintenance and ensuring optimal operational efficiency.
  • Environmentally Friendly: By preventing oil leakage into the sea, the PRIMAIR system supports sustainable marine operations.
  • Compact Design: The compact and efficient design fits into various stern tube configurations, offering flexibility and ease of installation.
