• On older machines
• Used for higher speeds (A2-principle)
• Used for higher pressure
• 100 % sealing between inlet and outlet
• ATTENTION:

Do not mistake it for special multi-channel DXSA types designed for rotating stretch blow-mouling machines

DXSA (old standard design)

• Replaces obsolete standard design DXSA
• B2 principle (siphon pipe rotates along with rotor)
• No wear at inner pipe
• For higher speeds
• For higher pressure
• Rotor not with shoulder but exchangeable rotor seal

Why H 3?

• Used on steam heated textile dryers
• Which are rather thin-walled
• Optional to H duo-flow versions
• Vacuum valve prevents damage of cylinders
• e.g. implosion
• H3 joints are used when dryers do not have their own

vacuum valve

• Standard sealing ring (synthetic carbon):

For steam and water , max. 250°C, 20 bar

• (optionally also for hot oil: < 10 r.p.m and pressure < 2 bar)
