Inverter Drives We can supply Ventilation Fans equipped with inverters, to give variable speed control.
Ducting Semi-rigid ducting can be supplied to suit any application, whether that is suction or forced ventilation.
Rigid Bends & Support Frames Rigid bends can be used in place of flexible ducting to maintain airflow and prevent duct collapse, particularly at the top of the shaft. These can be attached to support frames to bolt the bend to either the floor (at the top of a shaft) or to segment linings.
Anemometers Used to measure air speeds. Hot wire- low speed range, high accuracy. Used to measure airflow speed in tunnels/headings. Vane anemometer – Higher speed range. Used to measure airflow speed at duct outlets / fan inlets
