Air duct tube for cooker hood EICO 5674 — white, Ø 80 × 170 mm rectangular section

The EICO air duct tube for cooker hood (rectangular section 170 × 80 mm, nominal circular equivalent Ø 80 mm) is an accessory designed to connect a kitchen hood to exhaust ducting. Finished in white, it provides a clean visible surface where ductwork passes through cabinets or wall openings and offers a 550 mm depth for routing and alignment. The product is intended for extraction systems where a compact rectangular-to-round transition and a low-profile appearance are required.

Advantages

This air duct tube offers a compact rectangular profile that helps fit ventilation outlets into narrow cabinet or wall spaces while maintaining a nominal round-equivalent diameter for standard hood connections. The white finish integrates with most cooker hood designs and kitchen interiors. Its 550 mm depth provides flexibility when aligning the hood outlet to existing ductwork and reduces the need for additional connectors.

Suitable for

• Connecting domestic cooker hoods to exhaust ducts where a 80 mm nominal connection is required
• Installations with limited lateral space where a rectangular section (170 × 80 mm) fits better than a round duct
• Retrofit projects where existing duct runs require a compact, low-profile transition piece

When it may not be suitable

This duct tube is not intended for use with industrial extraction systems or applications that require larger airflow capacities than those supported by an 80 mm nominal diameter. It may not be suitable where fully circular rigid ducting is mandated by local building codes or where insulation, noise attenuation, or high-temperature resistance beyond typical domestic hood requirements is necessary.

Key specifications

• Cross-section dimensions: 170 mm × 80 mm (rectangular)
• Nominal circular equivalent diameter: 80 mm
• Depth for routing: 550 mm
• Finish: white
• Application: cooker hood exhaust connection

How to use

Position the rectangular section so it aligns with the hood outlet and the building ductwork, allowing the 550 mm depth to accommodate adjustments. Securely fasten the duct tube to the hood outlet using appropriate clamps or seals compatible with an 80 mm nominal connection to ensure airtight joints. Route the other end into the fixed duct or transition to circular ducting as required, checking for proper slope and unobstructed airflow. Finish the visible edges to match cabinetry or wall surfaces.

What to consider before purchase

• Verify that your cooker hood outlet uses an 80 mm nominal diameter or can adapt to a rectangular 170 × 80 mm section
• Check available installation depth and clearances to confirm the 550 mm routing length is appropriate
• Confirm that local ventilation regulations permit rectangular-to-round transitions and this material/finish

Usage recommendations

Ensure all joints are sealed and supported; inspect the connection after initial operation for air leaks. Use suitable clamps and, if needed, acoustic or thermal insulation on the external ducting rather than this short transition piece.
