Air exhaust grille with backdraft damper and shutter, SIGMA

Premium quality recessed air exhaust grilles, designed for those seeking the perfect combination of efficiency and aesthetics. These grilles are an ideal solution for modern homes, especially for cooker hoods, ensuring your ventilation system works flawlessly and looks great.

Key features:

• Integrated backdraft damper (non-return valve): The main advantage of these grilles is the built-in non-return valve. This smart system acts as a one-way barrier: it allows air to exit freely but automatically closes when the ventilation is turned off.
  • Benefit: No cold drafts from outside on windy days.
  • Protection: Effectively blocks odors, dust, and even insects from re-entering the room.
  • Efficiency: Helps maintain a stable room temperature and save energy.
• Elegant finish - choice of black, white, or stainless steel colors.
• Ideal solution for cooker hoods: These recessed grilles are specifically designed for use with powerful airflows, such as from kitchen cooker hoods. Their construction ensures minimal resistance to the exhausted air, allowing your cooker hood to operate at maximum efficiency.
• Universal sizes: SIGMA grilles are adapted to the most common ventilation duct standards. Available diameters: d125 mm or d150 mm.
