Diamond CA9/9/9 Centrifugal Ventilator With Isolated Caisson

This particular one is the Diamond CA9/9/9 Centrifugal. The frame is galvanized steel, and the isolated caisson is there to cut down fan noise reaching the kitchen. It's built to extract air mechanically where a passive canopy alone wouldn't shift enough volume. This one comes in at W600 x D600 x H600 mm overall and weighs 33 kg. It runs on 230V and connects via 230/1N 50HZ. It comes with a 1-year parts only warranty. Match the fan size to your ducting run rather than just the canopy above it, since undersizing costs you extraction performance.
