Non-return damper for cooker hoods and ventilation Ø150 mm

Key features

• Automatic non-return flap damper : it closes by itself as soon as the cooker hood or ventilation stops and only opens under the pressure of extracted air. No more cold air, moisture and odours coming back from the duct.
• Galvanised steel, stainless steel shaft and spring : galvanised steel body that resists corrosion and the humidity of extract ducts, lightweight aluminium flap, stainless steel shaft and spring. The return force is kept over time, without seizing or rust spots.
• Rubber seal for soft, silent closing : the perimeter seal makes the joint airtight and cushions the closing of the flap. The damper no longer rattles when wind blows into the duct, even at night.
• Male/male connector Ø 150 mm - DN150 : fits directly onto rigid ducts, pipes, flexible hoses and vent grilles of 150 mm diameter. Compatible with kitchen cooker hoods, bathroom extractor fans, vented tumble dryers and single or dual flow ventilation systems.
• Vertical or horizontal fitting in minutes : fits either way round, at the outlet or in-line on the duct. Push on, point the arrow in the airflow direction, secure: no special tools or skills needed.

What it is for

When the cooker hood or ventilation stops, the duct stays open to the outside: cold air comes down, moisture rises, odours come back and the wind rattles the duct. This ventilation damper closes the passage automatically as soon as extraction stops and only opens under the pressure of outgoing air. You keep the heat in your home and stop backdraughts.

Construction

Corrosion-resistant galvanised steel body, lightweight aluminium flap, stainless steel shaft and spring for a positive closure over time. The rubber perimeter seal makes the joint airtight and cushions the flap, even on windy days.

Installation

Ø 150 mm male/male connector, compatible with rigid ducts, pipes, flexible hoses and vent grilles of the same diameter. Vertical or horizontal fitting, at the outlet or in-line: push on, point the arrow in the airflow direction, secure. It takes a few minutes, with no special tools.
