  • Universal Media Passage: Designed with a single passage to accommodate all types of media, providing versatility for various machining needs.
  • Patented All-Media Technology: Operates with closed seals for coolant, transforms into a Pop-Off™ when pressure is released, and maintains a controlled leakage with a microscopic gap for pressurized dry air, thanks to innovative All-Media technology.
  • Adaptive Non-Rotating Element: The non-rotating element features a 0.7-3.0 mm axial movement, ensuring reliable sealing even in the face of thermal expansion of the spindle and variations in drawbar position.
  • Efficient Full-Flow Design: The design facilitates unimpeded fluid flow, preventing the entrapment of swarf or debris, thereby optimizing machining efficiency.
  • Durable Silicon Carbide Seals: Equipped with balanced mechanical seals made from silicon carbide, providing longevity and reliability even in challenging operating conditions.
  • Corrosion-Resistant Aluminum Housing: The anodized aluminum housing enhances corrosion resistance, ensuring durability and longevity in diverse machining environments.
