## Long description

The ALNOR NSL-315 internal connector is a professional-grade component engineered for the secure and airtight assembly of circular ventilation ducts. Designed to fit seamlessly within ducting systems, this connector ensures structural integrity and maintains consistent airflow throughout the network. The integrated high-quality gasket provides a robust seal, effectively preventing air leakage and enhancing the overall energy efficiency of your HVAC installation.
Advantages
This internal connector offers superior sealing capabilities thanks to its precision-engineered gasket, which minimizes pressure loss and noise within the ventilation system. Its durable construction ensures long-term reliability even in demanding environments, making it an essential choice for maintaining airtight standards in professional ductwork. The design facilitates quick and straightforward installation, significantly reducing assembly time while ensuring a stable and permanent connection between duct sections.
Suitable for
Connecting circular ventilation ducts in HVAC systems
Residential and commercial ventilation network installations
Maintaining airtight integrity in air supply and exhaust systems
Reducing air leakage in industrial ventilation setups
When it may not be suitable
This connector is specifically designed for circular ventilation ducts and will not be compatible with rectangular or oval ducting systems. It is intended for standard HVAC applications and may not be suitable for specialized environments involving high-temperature exhaust, corrosive gases, or extreme pressure conditions that require specialized materials.
Key specifications
Diameter: 315 mm
Material: Galvanized steel
Integrated gasket for airtight sealing
Type: Internal connector for circular ducts
How to use
To install the ALNOR NSL-315, insert the connector into the ends of the two circular ventilation ducts you wish to join. Ensure that the connector is pushed firmly into both sections until the gasket is fully seated against the inner walls of the ducts. The tight fit provided by the gasket will secure the connection and prevent air from escaping at the joint. No additional sealing tape or mastic is typically required due to the efficiency of the integrated gasket.
What to consider before purchase
Verify the diameter of your existing ventilation ducts to ensure compatibility with the 315 mm size
Check the material compatibility of your current ductwork
Ensure the installation environment does not exceed the operational limits of the connector
Usage recommendations
Regularly inspect the ventilation joints during routine maintenance to ensure the gasket remains properly seated and that the connection remains airtight over time.
