MEZ-SYPHON-FLANGE system 20 with injected sealing compound is an air duct profile for the manufacturing of air duct systems with high tightness requirements. By placing the sealing compound inside the MEZ-SYPHON-FLANGE you are able to meet the requirements of air tightness class C & D according to EN 1507.

The cant of the MEZ-SYPHON-FLANGE which makes it easier to insert the air duct wall and stabilises the mounting portion. Another feature which contributes to the optimal stability of the MEZ-SYPHON-FLANGE is the 45° supporting limb. To meet the high tightness requirements, the inner limb was designed with a slight cant and therefore it functions like a sealing lip.

• high tightness through integrated syphon
• profile for all purposes
• easy to insert the duct wall
