Wall bushing 250 mm – industrial flange for maximum throughput
The 250 mm bushing is the largest size we stock, built for industrial ventilation systems. Pair it with an Alu-Dec 250 mm duct for a permanent pass-through engineered to handle the highest air volumes.
Industrial and commercial applications
Greenhouses, large-scale grow facilities, warehouses and production environments run ventilation systems of 250 mm or larger. The bushing serves as the fixed wall or ceiling pass-through and must withstand high pressure, vibrations and years of continuous operation. The heavy-gauge steel construction ensures that reliability.
Professional installation recommended
Cutting a 250 mm hole through a load-bearing or concrete wall requires a diamond core drill and professional expertise. Leave this to an installer experienced in industrial ventilation. After fitting, seal around the flange with silicone or specialist sealant to prevent air leaks and moisture ingress. For homes and smaller projects, the 200 mm bushing is more appropriate.

Is the 250 mm bushing suitable for outdoor mounting?
The bushing itself is designed for wall mounting and is not weatherproof on its own. For exterior use, seal the flange edge with outdoor-grade silicone and fit a rain cap or louvre grille on the outside to keep out rain, wind and pests.
