This Lomanco Vent Turbine set should be used when a single turbine doesn’t provide enough ventilation and a stronger wind flow is needed. Ideal for multi-storey buildings such as office blocks and apartments that are over 7 storeys, the set features two of Lomanco’s most powerful vent, TIB14. Why should I use this wind-powered vent turbine? For installation in multi-storey apartment blocks and towers, this vent replaces conventional central electric ventilators for a quieter, cheaper and more efficient wind-powered vent system. The splitter provides two shafts that direct from two turbine heads into the building’s internal ventilation shaft. The set combines two of the most powerful Lomanco turbine, a TIB14, with a splitter and an installation base. The turbines are made entirely from aluminium so they’re rust-proof and requires no maintenance. The folded edges of the turbine vanes mean water cannot ingress into your ventilation shaft. A 14” turbine moves up to 37% more air than 12” so by installing two TIB14 turbine heads you’re increasing air flow by a large amount. Alongside all of these benefits both the TIB14s come with a lifetime warranty and the splitter and base come with a 2-year warranty. This set includes: 2 x Lomanco TIB14 14” turbine head Splitter (which must always be anchored) A base This product must be installed on the outlet of an existing vent shaft. 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.
