The GT160 steps up to 160mm ducting and bigger airflow. Position one runs at 400m3 per hour, position two at 800m3 per hour, so one fan covers calm and busy conditions. The silent German EBM Papst motor draws 65 to 100 watts. It suits rooms with two lights.
A digital external temperature sensor ships with the fan on a 4-metre cable, letting you read room conditions away from the motor. The mounting bracket is included; the mains cable is not. Pair the fan with a 160mm carbon filter for odour control across a larger space. The motor carries a one-year warranty.
