Item	Description
1	Seal face, stationary
2	Seat, rotating
3	Thrust ring
4	Spring
5	Shaft sleeve and seat retainer
6	Housing (size matched to installation space)
D	Separation gas

Extremely low leakage
Double arranged (co-axial) dry gas seal with just one pair of seal faces
Insensitive to oil contamination due to its special design
Wear-free, non-contacting operation in all conditions
Insensitive to radial vibrations due to axial sealing gap
Slow-roll or turning operation capable (static lift-off)
No limits regarding dew point of separation gas (silicon carbide instead of carbon)
Lower N2 consumption than any other system
N2 can be switched off during standstill – the gap will close and still provide the best oil sealing performance
Best in class oil sealing by extremely small sealing gap and sling effect of rotating ring
