## Summary description

Transformation piece ALNOR RPCL-315-250 (model RPCL-315-250) is a duct connector intended for joining or adapting circular duct sections. Designed for ventilation and air distribution systems, it provides a mechanical transition between differing diameters or configurations. Suitable for HVAC installation, maintenance and renovation projects where reliable duct coupling and airtight connection are required.

## Long description

The ALNOR RPCL-315-250 transformation piece is a duct connector from the RPCL series designed to join circular duct sections with differing diameters. Intended for ventilation and air distribution systems, this model provides a mechanical transition that helps maintain airflow continuity and supports airtight connections where a change in duct size or configuration is required. The connector is suitable for use in HVAC installation, maintenance and renovation projects that call for a reliable coupling between round ducts.
Advantages
The RPCL-315-250 offers a stable mechanical connection between ducts with different diameters, reducing the need for custom fabrication on site. Its design supports straightforward installation and integration into existing circular ductwork while helping to preserve airflow efficiency. The connector contributes to improved system sealing and reduces the risk of leaks at transition points when installed according to recommended practices.
Suitable for
 Residential and commercial HVAC duct transitions
 Ventilation system installation and renovation
 Maintenance tasks requiring replacement or adaptation of circular ducts
 Situations where an airtight coupling between different duct diameters is needed
Key specifications
 Type: circular duct transformation/connector
 Series: RPCL series
 Configuration: mechanical transition between two circular duct diameters
 Application: ventilation and air distribution systems (HVAC)
 Function: enables airtight coupling and diameter adaptation in duct runs
How to use
Position the RPCL-315-250 between the two circular duct sections to be joined, ensuring each duct end fits the corresponding side of the connector. Secure the connector to the ducts using appropriate fasteners or clamps for metal ductwork and ensure alignment to avoid airflow restrictions. Apply sealing materials or gaskets where required by local practice to achieve an airtight joint. Verify the connection visually and, if necessary, perform a leak test or pressure check as part of commissioning.
Usage recommendations
Use the RPCL-315-250 in conjunction with compatible circular ducts and fastening accessories of matching size. During installation, follow applicable HVAC standards and local building codes; use suitable sealants or gaskets to enhance airtightness and avoid excessive bending near the transition to maintain airflow performance.
