Gas guide

• replaces two shut-off dampers (one flue gas canal is always open)
• with sealing air 100% lock as per UVV/TRD
• very high impermeability with various sealing systems without sealing air (short seal length / little sealing air consumption)
• very little pressure loss (unimpeded cross-section, vane swivels in canal recess)
• excellent flue gas redirection (slanted position of the vane)
• simple control (one drive only)
• very little maintenance required (few mechanically moving parts)
• space-saving and inexpensive design
