If you go to 200mm duct diameter you can use this fan on 100ft lengths (smooth bore stuff). The fan is supplied with a terminal block and I can supply with pre -wired plug 13A 3 pin if you require it. Motor is out of air-stream so you can use it for shifting fumes and spray paint etc so long the motor is in a clean area and the fan has some filter attached.
