Specialized Cutter for Flexible Air Ducts

The specialized tool is designed for cutting plastic corrugated air ducts during the installation of ventilation networks. Using standard utility knives often results in oblique and uneven cuts, which can damage the rubber seals of distribution boxes and plenums during assembly. This cutter ensures a precise cut strictly at a 90-degree angle. The exact cutting geometry guarantees reliable connections (push-fit system), preventing static pressure losses and the generation of aerodynamic noise within the system.

Design and Operational Features

• Seal Protection: A precise cut along the corrugation groove prevents the formation of burrs that could cut rubber rings during the assembly of ventilation nodes.
• Installation Optimization: The shape of the guide arcs eliminates the need for prior marking of the duct. The tool automatically seats into the correct groove, reducing execution time.
• Operational Safety: The cutting blade is positioned between the guide elements of the body. This minimizes the risk of slipping and injury when working with hard plastic.
• Structural Precision: The tool modifications are strictly calibrated to standard duct diameters (50, 63, 75, and 90 mm), providing a tight grip without play or blade deviation.
• Durability: The blade is secured with screws and can be quickly replaced when dull, making the tool suitable for long-term professional use on construction sites.
