MEZ-SYPHON-FLANGE 40/L

MEZ-SYPHON-FLANGE 40/L - galv. (148LSB) – FLANGE Air duct profile with Butyl-Mastic for maximum airtightness in large-scale projects

The MEZ-SYPHON-FLANGE 40/L - galv. (148LSB) air duct profile is suitable for the construction of large air distribution systems. This all-round profile meets the highest standards of airtightness and guarantees reliable production processes. The integrated siphon geometry, combined with factory-applied Butyl-Mastic injection, ensures a reliable and uniform sealing process directly within the profile.

Large duct cross-sections and complex systems often cause problems. Leaks, manual sealing work and unstable joints frequently lead to rework. This costs time and increases costs. This air duct profile offers a well-thought-out solution to these challenges. The integrated seal and the profile’s robust construction guarantee consistent quality. This allows you to manufacture air ducts efficiently in accordance with tightness classes C and D as per the DIN EN 1507 standard.

Technical highlights

• System 40/L – optimised for large-format air ducts
• Galvanized steel (148LSB) for reliable corrosion protection
• Factory-applied Butyl-Mastic injection for uniform Sealing
• Integrated siphon geometry to minimise air leaks
• Folded insertion bevel for easy duct installation
• Inner flange with sealing lip function for additional sealing
• Sturdy support flange for high dimensional and torsional rigidity
• Suitable for tightness classes C & D in accordance with DIN EN 1507
