MEZ-SYPHON-FLANGE 40/L – V2A

MEZ-SYPHON-FLANGE 40/LE - V2A: Airtight, sturdy, and quick to install in ductwork

The MEZ-SYPHON-FLANGE 40/LE, a duct profile made of V2A stainless steel, prioritizes airtightness. The integrated siphon geometry securely guides the sheet metal edge, acts as a sealing lip, and prevents leaks right from the start. Profile length 5,000 mm, material thickness 1.00 mm; package size 500 m.

Leaks at frame joints cost energy, time, and patience—especially in airtight systems (ATC 2/3 or Classes C/D according to DIN EN 1507). Common cause: profiles without a defined sealing line and time-consuming resealing at the joint surface.

Technical Highlights

• Integrated siphon and slightly chamfered inner leg: secure guidance of the duct wall, less rework, high tightness.
• Optional injected sealant: meets tightness classes C/D according to DIN EN 1507; VDI 6022-compliant applications possible.
• 45° support leg and defined fastening area: stable frame for welding, riveting, screwing, or pressing.
• Quality from European steel expertise: reliable material quality & focus on sustainability

Key Benefits

• High sealing performance thanks to integrated siphon geometry
• Sturdy 45° support flange, less rework during assembly
• Standard length 5,000 mm, 1.00 mm – ideal for series production (minimum order quantity 500 m)

Additional Benefits at a Glance

• Planning reliability thanks to standardized lengths/packaging units
• Fewer complaints thanks to a tight-fitting system
• Lower leakage rates mean stable airflow and less energy loss during operation

Installation

• Faster installation because the beveled edge makes insertion easier
• The profile tab secures the connectors
• Less need for additional sealing at the joints

Why is this air duct profile right for you?

With the MEZ‑SYPHON‑FLANGE 40/LE – V2A, you get an air duct profile that consistently combines tightness, stability, and installation efficiency. The integrated siphon geometry and precise sheet metal guidance not only reduce leaks but also lower manufacturing and service costs over the entire system lifecycle.
