DOSPEL D/KPI 110x55 vertical flat elbow 007-0222 for ventilation ducts

Vertical flat elbow DOSPEL D/KPI 110x55 (model 007-0222) is a compact ventilation fitting designed to change the airflow direction in rectangular duct systems. With nominal cross-section dimensions of 110 x 55 mm, this vertical corner transition links flat or rectangular duct sections in vertical runs, enabling compact routing in confined spaces and providing a stable connection for residential and light-commercial ventilation or extraction paths.

Advantages

The DOSPEL D/KPI 110x55 vertical flat elbow offers a space-saving profile that simplifies duct routing where height or depth is limited. Its geometry maintains a consistent internal passage to reduce turbulence and pressure loss compared with improvised transitions. Constructed to fit standard flat duct dimensions, the elbow enables reliable joints and straightforward integration with compatible rectangular ductwork.

Suitable for

• Changing airflow direction in rectangular/flat ventilation ducts
• Compact vertical transitions in kitchen or bathroom extraction systems
• Applications where space constraints require low-profile duct fittings
• Residential and small commercial HVAC duct routing

Key specifications

• Nominal cross-section: 110 x 55 mm (rectangular/flat)
• Orientation: vertical elbow for directional change
• Function: connects and redirects flat duct sections
• Typical use: ventilation and extraction ductwork

How to use

Fit the DOSPEL D/KPI 110x55 vertical flat elbow between two matching rectangular duct sections, ensuring that the internal faces align for a smooth airflow passage. Secure connections with appropriate clamps, screws, or duct tape as required by the installation practice, and seal joints to prevent air leaks. Position the elbow so the airflow follows the intended vertical change without kinking flexible ducts; check clearances to avoid obstruction and allow access for maintenance.

Usage recommendations

Confirm that adjoining duct dimensions match the elbow’s nominal 110 x 55 mm profile before installation. Use compatible sealing materials and fasteners for a durable, low-leak connection. Avoid sharp bends immediately before or after the elbow to reduce pressure loss and noise; incorporate gradual transitions where possible.
