Lomanco TIB14 Vent Turbine Head is a 14” diameter ventilation turbine head that can be installed directly onto new or existing 14” pipes. Installing this product helps remove unwanted moisture from buildings, working towards protecting the longevity of the building and its materials, including insulation, shingles and cladding. This vent turbine is powered solely by wind, removing the need for electric vents and lowering bills. To ensure its safety this turbine has been tested to withstand winds of up to 110 mph thanks to its riveted, spider-type construction. There are 21 curved vanes that make up the turbine head. Each of them has rolled edges in order to stop water entering the pipe and the aluminium manufacture of this product ensures there’s no rust. All Lomanco vent turbines have a Lifetime Transferable Warranty, although we doubt you’ll ever need it given the all-aluminium construction and permanently lubricated ball bearings within this turbine head. Please note, this lifetime warranty applies to residential use only. In instances where a Lomanco turbine has been installed for commercial use, the product is covered by a 15 year warranty. Lomanco TIB14 Vent Turbine Head comes in aluminium, brown, white or black.
