This Lomanco P14 vent turbine base is manufactured from galvanised steel for lasting strength and durability. It can be used as a base for 14” turbine heads or for tube splitters. To create a single vent turbine system, a Lomanco BIB14, TIB14 or BEB14 vent turbine head must be purchased alongside this base. When installed correctly with the matching Lomanco turbine heads, 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 45 so it can be used on a range of domestic, commercial, residential and industrial roofs.
