## Long description

The ALNOR NSL-200 ventilation sleeve is a precision-engineered duct connector designed to facilitate secure and airtight connections within HVAC systems. Constructed from high-quality materials, this component is specifically engineered to join ventilation ducts seamlessly, ensuring structural integrity and consistent airflow throughout the network. The inclusion of an integrated EPDM rubber gasket provides a reliable seal that effectively minimizes air leakage, thereby enhancing the overall energy efficiency and performance of the ventilation system.
Advantages
The primary benefit of the ALNOR NSL-200 is its superior sealing capability provided by the factory-fitted EPDM rubber gasket. This design feature eliminates the need for additional sealants during installation, saving time and reducing the risk of improper application. The sleeve is built for durability and resistance to environmental factors, ensuring a long service life in both residential and commercial ventilation applications. Its standardized dimensions allow for quick and easy integration into existing ductwork, promoting a professional finish and reliable operation.
Suitable for
Connecting circular ventilation ducts in HVAC systems
Residential ventilation network installations
Commercial building air distribution systems
Upgrading or repairing existing ventilation ductwork
When it may not be suitable
This ventilation sleeve is designed specifically for standard circular ducting systems. It may not be suitable for non-standard duct shapes or specialized industrial applications involving high-temperature gases or corrosive chemical vapors that exceed the material specifications of galvanized steel and EPDM rubber.
Key specifications
Diameter: 200 mm
Material: Galvanized steel
Seal type: Integrated EPDM rubber gasket
Application: Airtight duct connection
How to use
To install the ALNOR NSL-200, ensure that the ends of the ventilation ducts are clean and free of debris. Slide the sleeve over the end of one duct until it reaches the center stop, then insert the second duct into the opposite side of the sleeve. Ensure the connection is firm and that the EPDM gasket is properly seated against the inner wall of the ducts to maintain an airtight seal. Secure the connection with self-tapping screws or rivets if required by local building codes or system pressure specifications.
What to consider before purchase
Verify the diameter of your existing ductwork matches the 200 mm specification
Ensure the material compatibility with your current ventilation system
Check local building regulations regarding duct connection methods
Usage recommendations
For optimal system performance, always ensure that the ducts are cut squarely and deburred before inserting them into the sleeve. Regularly inspect connections during routine maintenance to ensure the integrity of the seal remains intact over time.
