ALNOR BPL-45-160 Ventilation Duct Bend with Gaskets 45 Degrees 160mm

The ALNOR BPL-45-160 is a high-quality 45-degree ventilation duct bend engineered for precise airflow management in HVAC systems. This component is specifically designed to facilitate smooth directional changes within circular ductwork, ensuring optimal system efficiency. Constructed from durable galvanized steel, the fitting offers excellent resistance to corrosion and mechanical stress, making it a reliable choice for both residential and commercial ventilation projects.

Advantages

The primary benefit of this ventilation bend is its integrated EPDM rubber gasket system, which provides a superior airtight seal between connected duct sections. This design significantly minimizes air leakage, which in turn reduces energy consumption and prevents pressure drops throughout the ventilation network. Furthermore, the airtight connection helps to dampen noise generated by airflow, contributing to a quieter indoor environment. The robust galvanized steel construction ensures long-term structural integrity and protection against environmental factors.

Suitable for

• Residential ventilation and air conditioning systems
• Commercial HVAC installations
• Air supply and exhaust ductwork
• Systems requiring airtight connections to minimize energy loss

When it may not be suitable

This product is designed specifically for standard circular ventilation ducts and may not be compatible with non-standard duct shapes or flexible hoses without appropriate adapters. It is not intended for use in high-temperature industrial exhaust systems or environments where corrosive chemical vapors are present, as these conditions may degrade the galvanized coating and the EPDM rubber gaskets.

Key specifications

• Angle: 45 degrees
• Diameter: 160 mm
• Material: Galvanized steel
• Sealing: Integrated EPDM rubber gaskets
• Compatibility: Standard circular ventilation ducts

How to use

To install the ALNOR BPL-45-160, ensure that the duct ends are clean and free of debris. Insert the bend into the corresponding ventilation duct until the gasket is fully seated within the connection point. Secure the joint using self-tapping screws or rivets to ensure mechanical stability. It is recommended to verify the alignment of the ductwork before final fixation to prevent unnecessary stress on the joints.

What to consider before purchase

• Verify the diameter of your existing ductwork matches the 160 mm specification.
• Ensure the 45-degree angle is appropriate for your specific installation layout.
• Check that the environment is suitable for galvanized steel and EPDM rubber components.

Usage recommendations

For optimal performance and system longevity, ensure that all connections are properly supported by duct hangers to prevent sagging or misalignment. Regularly inspect the joints during routine maintenance to confirm that the seals remain intact and the system remains airtight.
