Why this extraction fan earns its place
This Combisteel double-skin fan box is purpose-built for commercial extraction systems where space is tight and noise matters. The double-skin construction provides thermal and acoustic insulation, reducing heat loss through the ductwork and keeping fan noise contained. At 450 mm cube, it sits snugly in plant rooms, ceilings, or back-of-house spaces without dominating your footprint—ideal for retrofits or tight site configurations.
The 1400 mm duct connection (7/7 specification) integrates directly into your extraction system. At 20 kg, it's manageable for installation and doesn't demand over-engineered fixings or structural support. This is a component that earns its place in a well-designed extraction rig without drawing attention to itself.
