This fan comes with two speeds of which both can be used as long as the correct control switch is installed, this needs to be a three position switch that allows you to select either of the fan speeds or turn the fan off. Airflow recommends our own switch part no 9041315 ASIN B00MEEZTI8 which is available on this site.This fan is less bulky than larger in-line centrifugal fans and can be installed in loft spaces or service shafts for remote extraction.With high flow / high pressure development characteristics they can be used with flexible ducting, round rigid ducting and flat duct channel systems to ensure compliance with Building Regulations, ensuring installed performance and extraction conditions are met.Combining two Aventa fans allows for even more powerful operation. Mounting in parallel (side by side) doubles the air flow, whilst two fans in series (one behind the other) leads to a doubling of the air pressure for longer duct runs.The fans are easily serviceable by undoing two clips, there is no need to undo the ducting that is connected to either end of the fan.
