The Bird Guard 400/450mm (BGZ400) is designed for ESR and VSR fans with diameters from 400mm to 450mm. This commercial fan accessory provides effective protection against birds and debris, helping maintain safe and efficient ventilation. Built for durability and ease of installation, it is suitable for both indoor and outdoor commercial ventilation applications.
Note: The original product overview mentions “Fan Size: 400 — 240mm,” which seems to be a typo. The corrected range used here is 400 – 450mm to match the product title.
