Sealing

Air riding seal between gearbox and compressor section

• Contact-free
• No detectable leakage in the operating range
• Vaccum pressure resistant – thus eliminating the need for bypass control
• Forms a stabilizing gas cushion from approx. 7,000 rpm
• No wear, no friction, no power loss
• Self-reinforcing at underpressure and overpressure up to 10 bar
• Speed-stable up to at least 130,000 rpm
• Extremely compact & durable
