The BGL540 is a louvre manufactured from white painted aluminium designed for mounting on the outside of wall fans with an overall frame dimension of 540 × 540 mm. The louvre blades are extremely light and open automatically with the slightest airflow from the fan. When the fan stops, the blades close again and protect the space against cold air, moisture and rain from outside. The white aluminium coating protects against corrosion, which is important in the food processing industry and in agricultural environments with high humidity and chemical compounds such as ammonia.

The louvre is mounted on the exterior of the building at the fan opening. The overall dimension (B) is 540 × 540 mm and the inner aperture (A) is 485 × 485 mm. Depth is 42.5 mm (C) and 46 mm (D). The louvre suits wall fans with a frame dimension in the range of 490–540 mm and is compatible with, among others, the Ziehl-Abegg FC040 range.

What is the BGL540 Shutters and why should you choose it?

The BGL540 is an aluminium louvre designed as an accessory for wall fans in agriculture, industry and food processing environments. Without a louvre, the fan opening remains permanently open to the outside environment, causing draughts, heat loss and risks of moisture ingress when the fan is not running. The BGL540 addresses this with lightweight blades that open automatically at the slightest increase in air pressure and close immediately when the fan stops. The white painted aluminium resists corrosion and is easy to clean, meeting the requirements of food handling and agricultural environments.

What environments is the BGL540 Fan Shutters suited to?

The louvre suits mounting on wall fans in poultry houses, piggeries, cattle barns, food processing factories, commercial kitchens, industrial premises and warehouses. The corrosion-protected white painted aluminium withstands agricultural environments with ammonia and high humidity. Mounting is on the exterior of the building directly at the fan opening. The louvre protects against cold, rain, snow and insects when the ventilation is not running.

Frequently Asked Questions (FAQ)

Does the BGL540 Shutters fit the Ziehl-Abegg FC040 range and other wall fans with a 400mm diameter?

Yes, the BGL540 louvre has an overall dimension of 540 × 540 mm and an inner aperture of 485 × 485 mm, which suits wall fans with a frame dimension in the range of 490–540 mm, including the Ziehl-Abegg FC040 range. The louvre is mounted on the exterior of the building at the fan opening. Always check the fan's exact frame dimensions against the louvre aperture (A: 485 × 485 mm) before installation.

What material is the BGL540 louvre made from and why does it matter?

The BGL540 louvre is manufactured from aluminium with a white painted finish. The aluminium provides high corrosion resistance against moisture, ammonia and chemical compounds found in agricultural and food processing environments. The white coating further reinforces the corrosion protection and makes the louvre easy to clean. The blades are very lightweight and open at the slightest airflow from the fan without adding significant resistance to the ventilation system.

What sets the BGL540 louvre apart from fans with built-in automatic louvres on Verktygsgrossen?

The BGL540 is a standalone outdoor louvre mounted separately on the exterior of the building and can be combined with fans that lack built-in louvres, such as the Ziehl-Abegg FC035 and FC040. The louvre protects against cold, rain and snow from outside, whereas a built-in indoor louvre primarily prevents backflow indoors. The white painted aluminium of the BGL540 is designed for outdoor use and withstands direct weather exposure. The overall dimension of 540 × 540 mm (inner aperture 485 × 485 mm) suits most wall fans in the 400 mm class.
