This Lomanco P8 vent turbine base is manufactured from galvanised steel for lasting strength and durability. It can be used as a base for the Lomanco IB8 turbine head and this will need to be purchased separately along with this base for a complete ventilation system. When installed correctly with the matching Lomanco IB8 turbine head, the completed system will ventilate a mix of roofs, vent shafts, attics, production plants, cellars and more. The effective ventilation turbine will expel any unwanted moisture improving the life span of the roof and the building below. Turning with the wind, this vent turbine system once installed will continuously ventilate without any need for electricity, perfect for saving costs and emissions. The square base will adjust to roof pitches from 0 to 27 so it can be used on a range of domestic, commercial, residential and industrial roofs.
