Product information

Description

The ALNOR RPCL-125-100 is a professional-grade ventilation passage designed to facilitate the connection between circular air ducts of varying diameters. This adapter serves as a critical component in HVAC systems, allowing for a seamless transition between 100 mm and 125 mm ducting. Engineered with a high-quality integrated gasket, the unit ensures a secure and airtight connection, which is essential for maintaining optimal airflow pressure and system efficiency in both residential and commercial ventilation networks.

Advantages

The primary benefit of the ALNOR RPCL-125-100 is its robust construction and precision engineering, which guarantees a tight fit and reduces the risk of air leakage within the ductwork. By utilizing this adapter, installers can easily modify duct diameters without the need for complex custom fabrication, saving time and labor costs. The inclusion of a factory-fitted gasket simplifies the installation process, as it eliminates the need for additional sealing materials while providing a reliable barrier against pressure loss.

Suitable for

  • Connecting circular ventilation ducts of different sizes
  • Residential HVAC system upgrades
  • Commercial ventilation and air conditioning installations
  • Adapting ductwork from 100 mm to 125 mm diameters

When it may not be suitable

This ventilation passage is specifically designed for circular duct systems and is not compatible with rectangular or oval ductwork. It should not be used in environments where the air temperature exceeds the material's thermal resistance limits or in systems carrying corrosive or highly abrasive substances.

Key specifications

  • Connection type: Circular duct adapter
  • Diameter range: 100 mm to 125 mm
  • Material: Galvanized steel
  • Seal: Integrated rubber gasket

How to use

To install the ALNOR RPCL-125-100, ensure that the duct ends are clean and free of debris. Insert the smaller end of the adapter into the 100 mm duct and the larger end into the 125 mm duct. The integrated gasket will provide the necessary friction and seal to hold the connection in place. For permanent installations, it is recommended to secure the joints with self-tapping screws or duct tape to ensure structural integrity under high-pressure conditions.

What to consider before purchase

  • Verify the exact diameter of your existing ductwork
  • Check the space availability for the adapter length
  • Ensure the material is compatible with your specific ventilation environment

Usage recommendations

Regularly inspect the connection points within your ventilation system to ensure that the gasket remains seated correctly and that no air leakage has developed over time due to thermal expansion or vibration.
