GM Bypass Element with 1x75 Rubber Connectors (Type A)

The GM bypass element (air tunnel or crossover) is a specialized installation assembly designed for crossing a single ventilation run, a flat duct, or other utilities in conditions with limited ceiling void space.

This modification (Type A) has a bypass channel depth of 54 mm, allowing it to safely cross standard flat ducts up to 50 mm in height. The use of rubber connectors in the GM series guarantees high connection airtightness without additional sealants and helps reduce structural noise. The well-thought-out housing geometry maintains full channel throughput at a minimal installation height.

The product housing is made of galvanized steel, ensuring corrosion resistance and mechanical strength under the pressure of building structures.

Design Features:

• Bypass Geometry: The channel depth of 54 mm allows for easily crossing over obstacles up to 50 mm high.
• Duct Connection: Rubber connectors provide a snug fit for flexible ducts and reliable airtightness. The elasticity of the material helps partially dampen system vibrations.
• Installation: Mounting holes (brackets) are provided at the corners of the housing for secure attachment to load-bearing structures.

Technical Specifications:

• Housing Material: Galvanized steel
• Connector Material: Rubber
• Number of Outlets: 1 inlet / 1 outlet (single bypass)
• Connection Diameter: 75 mm
• Bypass Depth: 54 mm
• Overall Dimensions (Length x Width x Height): 371 x 180 x 85 mm
• Compatibility: Standard 75 mm flexible circular duct systems and flat obstacles up to 50 mm
