Hood accessory Elica CURVA RETTANGOLARE VERTIC 90 deg — rectangular vertical 90° duct curve

Elica CURVA RETTANGOLARE VERTIC 90 deg is a hood accessory designed as a rectangular vertical 90° duct curve for kitchen ventilation systems. It provides a compact right-angle connection between the cooker hood outlet and vertical ductwork, enabling controlled redirection of exhaust airflow in domestic or light-commercial extractor installations. The component is intended to fit rectangular duct profiles and to streamline airflow where space or layout requires a perpendicular change in direction.

Advantages

This rectangular vertical 90° curve offers a stable and reliable redirection of exhaust air with minimal installation complexity. The rigid profile preserves duct geometry to reduce turbulence and potential noise compared with improvised bends. It is suitable for typical kitchen ventilation materials and compatible with installations where a neat, space-saving vertical turn is required.

Suitable for

• Domestic kitchen extractor hoods that require a 90° vertical change of direction
• Light-commercial kitchen ventilation systems with rectangular ductwork
• Retrofit installations where existing ducting must be redirected without major reconstruction
• Scenarios where maintaining duct geometry helps reduce airflow resistance and noise

When it may not be suitable

This accessory is designed specifically for rectangular duct profiles and may not fit round or proprietary oval ducts without additional adaptors. It is intended for ventilation routing and does not include sound insulation, filters, or fan components—those must be provided separately when required by the installation.

Key specifications

• Function: rectangular vertical 90° duct curve for exhaust airflow redirection
• Compatibility: intended for rectangular kitchen duct profiles and extractor hood outlets
• Orientation: vertical 90-degree change of direction
• Application: domestic and light-commercial kitchen ventilation
• Performance considerations: maintains duct geometry to minimise turbulence

How to use

Install the curve between the hood outlet and the vertical section of the ductwork where a right-angle turn is required. Ensure mating faces are clean and align the rectangular profiles so the component fits flush with adjacent duct sections. Secure connections with appropriate fasteners or sealing tape as specified by the hood and duct manufacturers, and check for air leaks after installation. Use additional adaptors or reducers if the existing duct dimensions differ from the curve's profile.

What to consider before purchase

• Confirm the rectangular duct dimensions and hood outlet size to ensure a correct fit
• Verify that a vertical 90° turn is appropriate for airflow and does not exceed system resistance limits
• Check whether additional components (adapters, seals, clamps) are needed for installation
• Consider noise and airflow implications of a right-angle bend in your specific ventilation setup

Usage recommendations

For best performance, keep the number of abrupt directional changes to a minimum and use smooth, secure joints. After installation, test the hood at typical operating settings and inspect for any airflow reduction or increased noise; if necessary, incorporate straight duct runs or gradual transitions elsewhere in the system to optimise ventilation efficiency.
