Round stainless steel exhaust grille — durable, weatherresistant ventilation for walls and ceilings Key benefits Reliable corrosion resistance: Made from longlasting stainless steel to resist erosion and retain structural integrity in both indoor and outdoor settings, reducing the need for early replacement. Effective moisture and smoke clearance: Angled louvers are engineered to promote fast release of smoke and condensation while directing rainwater away from the duct opening, keeping your ventilation working when it matters. Cleaner indoor air: Tightly spaced slats block leaves, insects and common outdoor debris from entering the duct, helping maintain clearer airflow and protecting downstream equipment. Simple compatibility and installation: Designed to fit standard 100 mm and 150 mm round wall or ceiling openings and common ducting systems; mounts securely on flat surfaces for straightforward installation. Features and performance Material: quality stainless steel construction for long service life and low maintenance. Design: Round grille with angled louvers balances airflow efficiency and weather protection to reduce backflow of water and ingress of contaminants. Fit: Suited to 100 mm and 150 mm diameter duct openings, making it compatible with many residential and lightcommercial ventilation systems. Protection: Closeset slats prevent large debris and pests from entering the duct while preserving adequate exhaust airflow. Typical applications Bathroom or kitchen exhaust: Use as the external termination for extractor fans to vent steam and odors while keeping rain and leaves out. Laundry or utility room vents: Fit to dryer or utility exhaust ducts to protect equipment and plumbing from clogging by debris. Small ventilation outlets on building exteriors or ceiling flues: Provide a durable, lowmaintenance termination for HVAC or workshop ventilation runs.
