Everything for Your Cooker Hood – A Complete Guide to Perfect Kitchen Ventilation

Efficient operation of your cooker hood is essential for fresh and pleasant air in the kitchen. In our Everything for Your Cooker Hood category you will find everything you need to optimally connect your hood to the wall vent – from various types of hood ducts and ventilation ducts, to clamps, transition pieces, couplers, and more. With the right products you will improve airflow, reduce noise and ensure flawless operation of your cooker hood.

How to choose the right duct for your cooker hood?

Choosing the right hood duct is crucial for smooth operation. Hood ducts are available in various diameters, materials and shapes, allowing you to tailor them to the needs of your kitchen.

Types of cooker hood ducts

1. Flexible hood ducts

   • Ideal for installation in hard-to-reach spaces or wherever flexibility is required.
   • Suitable for connections with bends or over longer distances.

2. Ventilation ducts

   • Intended for general ventilation and more powerful cooker hoods.
   • Available in various diameters: hood duct 100 mm, hood duct 125 mm, hood duct 150 mm, hood duct 160 mm.

How does duct diameter affect performance?

Duct diameter has a major impact on airflow and noise levels:

• A hood duct of 100 mm or 125 mm is suitable for less powerful hoods and shorter runs.
• A hood duct of 150 mm or 160 mm enables better airflow, quieter operation and is recommended for more powerful hoods.

Connecting the cooker hood to the wall vent

Correct installation of the hood ensures its efficiency. The connection typically involves the use of ducts, clamps and accessories that provide solid and airtight joints.

Transition pieces and couplers

• Transition pieces are indispensable when the duct diameter needs to be adapted to the wall vent (e.g. from 160 mm to 100 mm).
• Couplers allow you to connect two ducts of the same or different diameter.

Bends and grilles

• 45° bends allow you to adjust the duct direction without affecting airflow.
• Grilles serve as a finish for the wall vent and prevent the ingress of dirt and insects.

Tips for reducing noise and increasing airflow

Although a cooker hood is designed for efficient air extraction, its performance also depends on the ducts and accessories:

1. Choose a larger duct diameter: Larger ducts (e.g. hood duct 150 mm or 160 mm) reduce air velocity, which lowers noise.
2. Use smooth ducts: Smooth ducts improve airflow compared to flexible ducts, which have an uneven inner surface.
3. Seal the joints: Quality clamps prevent air leakage and improve ventilation efficiency.

How to choose the right hood power?

The power of a cooker hood should match the size of the kitchen and how often you cook:

• Hoods with lower airflow (up to 300 m³/h): Compatible with ducts of 100 mm or 125 mm diameter.
• Medium-capacity hoods (300–500 m³/h): Recommended ducts of 125 mm or 150 mm diameter.
• Powerful hoods (over 500 m³/h): Use ducts of 150 mm or 160 mm diameter to prevent noise and increase efficiency.

Frequently Asked Questions (FAQ)

Which cooker hood duct diameter is best?

The choice of diameter depends on the power of your hood: less powerful hoods work well with 100 mm or 125 mm, while more powerful hoods require 150 mm or 160 mm.

How can I reduce cooker hood noise?

For lower noise, choose ducts of a larger diameter with a smooth inner surface. Properly seal all joints to prevent vibrations.

Can I use a flexible hood duct for long runs?

Yes, but keep in mind that the uneven interior of a flexible duct can slightly reduce airflow. For long runs, smooth ducts are recommended.

How do I correctly connect the hood to the wall vent?

Use a duct of the appropriate diameter, couplers for connecting and clamps for sealing. Finally, finish the wall vent with a grille to prevent the ingress of dirt.

Can I use a cooker hood duct for general ventilation?

Of course, ventilation ducts are universal and suitable for both cooker hoods and other ventilation systems.

Is it important for the duct to be smooth?

Yes, a smooth duct reduces air resistance and increases ventilation efficiency. It also enables quieter operation. Flexible ducts, however, are always easier to install and very convenient.
