Exhaust hood connection reducer AWENTA ROK 120/100 mm white

The AWENTA ROK 120/100 mm connection reducer in white is a circular duct adapter designed to join ventilation pipes of different diameters. It provides a straightforward mechanical transition from a 120 mm nominal duct to a 100 mm nominal duct, enabling compatibility between exhaust hoods and smaller ventilation runs. The white finish is suitable for visible installations in domestic kitchens or utility areas and for integration with common ventilation components.

Advantages

This connection reducer offers a simple and reliable method to reduce duct diameter while maintaining a compact profile. Its circular shape preserves airflow characteristics and makes installation into standard round duct systems fast and uncomplicated. The white surface allows for discreet appearance where the reducer remains visible and is compatible with typical ventilation fittings and clamps.

Suitable for

• Connecting kitchen exhaust hoods to smaller ventilation ducts
• Adapting existing circular ductwork when downsizing a run
• Domestic and light-commercial ventilation systems requiring diameter reduction

Key specifications

• Material: corrosion-resistant sheet (suitable for ventilation use)
• Nominal inlet diameter: 120 mm
• Nominal outlet diameter: 100 mm
• Shape: circular reducer with stepped profile for secure jointing
• Finish: white surface suitable for visible installations

How to use

Fit the larger end of the reducer onto the 120 mm duct and insert the smaller end into or over the 100 mm duct depending on system layout. Secure both joints with appropriate clamps or metal tape to ensure airtight connection and reduce vibration. Verify that the reducer is aligned with the duct run to avoid sharp bends or constrictions that could impede airflow.

Usage recommendations

The reducer is intended for use in ventilation systems where a controlled reduction in duct diameter is required. To maintain system performance, avoid combining multiple consecutive diameter reductions without recalculating airflow requirements. Use suitable sealing and fastening methods and check compatibility with nearby components such as filters, dampers, or flexible ducting.
