Round ventilation duct EICO 4534, adjustable length 20–62 cm, white, 220 mm depth

EICO 4534 is a white round ventilation duct with an adjustable length from 20 to 62 cm and a fixed depth of 220 mm. The component is intended for inline connection in domestic ventilation and extraction systems, providing a compact adjustable segment that fits between fixed duct runs or between a hood outlet and existing ducting. The white finish allows integration into visible installations where a neutral appearance is required.

Advantages

The adjustable length design allows precise fitting without cutting rigid ductwork, reducing installation time. The round profile minimizes airflow resistance compared with non-circular shapes and supports standard circular connectors. A shallow 220 mm depth makes the duct suitable for installations with limited clearance while maintaining adequate airflow capacity. The white surface is easy to clean and coordinates with common kitchen and HVAC components.

Suitable for

• Connecting kitchen hoods to existing circular ductwork
• Extending short runs in residential ventilation systems
• Adapting duct layouts where adjustable length is required for accurate alignment

Key specifications

• Adjustable length: 20–62 cm
• Depth: 220 mm
• Shape: round
• Finish: white
• Intended use: ventilation / extraction duct segment

How to use

Measure the gap between the two connection points and set the duct to the required length within the 20–62 cm range. Slide the ends into the corresponding circular connectors or flanges and secure with appropriate clamps or screws depending on the existing duct system. Ensure the 220 mm depth orientation and alignment are correct to avoid kinks or misalignment that could increase airflow resistance. After installation, check for airtight joints and make adjustments or apply sealing where necessary.

Usage recommendations

For best performance, use the duct as part of a continuous, correctly sized round ventilation system and avoid sharp bends immediately adjacent to the segment; inspect connections periodically for leaks and re-tighten clamps after initial operation.
