## Summary description

DOSPEL D/ZD 104/110x55M is a ventilation connector for joining ducts with variable cross-sections. Designed to adapt from Ø104/110 mm to a 55 mm rectangular section, it enables connection between circular and reduced rectangular or flat ducts. Suitable for HVAC installations, exhaust systems and ducting modifications where transition between duct shapes and sizes is required.

## Long description

DOSPEL D/ZD 104/110x55M is a ventilation variable-section connector designed to join circular ducts with a reduced rectangular section. The part provides a transition from Ø104/110 mm round ducts to a 55 mm flat or rectangular outlet, allowing installation in HVAC systems where duct shape or size must change. Made for use in ventilation, exhaust and air distribution applications, the connector supports compact routing and straightforward adaptation between standard round ductwork and slimmer rectangular profiles.
Advantages
The connector offers a reliable mechanical transition between circular and rectangular ducts without the need for custom fabrication. Its standardized round diameter simplifies attachment to common Ø104/110 mm fittings while the 55 mm rectangular end provides a low-profile outlet for confined spaces. The component is compact and intended for rapid integration into existing ducting layouts, reducing installation time for modifications and repairs.
Suitable for
Domestic and commercial ventilation systems requiring shape transition
Exhaust extraction where a round duct must connect to a flat or rectangular inlet
Ducting modifications and retrofits in tight spaces
Bathroom, kitchen and appliance venting when adapting between sizes
Key specifications
Input diameter: compatible with Ø104/110 mm circular ducts
Output section: rectangular/flat 55 mm width profile
Function: transition/adapter between round and reduced rectangular ducting
Application area: ventilation, exhaust and air distribution systems
Installation: inline connector for duct joins and retrofits
How to use
Insert the circular end onto the Ø104/110 mm duct and secure it with an appropriate clamp or fastening method compatible with the duct material. Align the rectangular 55 mm outlet with the mating flat or rectangular duct section and fasten to ensure an airtight or leak-minimised joint. Verify the connection orientation and support the assembly to avoid stress on the ducts. Seal joints with suitable duct tape or sealant where required by the installation standards.
Usage recommendations
Use the connector with compatible Ø104/110 mm round ducts and corresponding 55 mm rectangular sections. Check material compatibility and local ventilation regulations when sealing and fastening. For optimal airflow and noise performance, avoid sharp bends immediately adjacent to the transition and provide mechanical support to prevent sagging.
