This Lomanco Vent Turbine Set comes with a 14” BEB (356mm) turbine and an electric ventilator and is best placed as an alternative to central electric ventilators in multi-storey buildings such as apartment and tower blocks. The vent turbine sits externally on the top of ventilation shafts to use the wind to remove any unwanted odours from units in a building, with the electric ventilator giving the vent an extra boost if there are poor weather conditions or the tenants choose to open the vents. Tenants can choose to open and close their individual vent outlets if small axial ventilators are used with this Lomanco turbine, as recommended. Why should I use a wind powered vent turbine? Lomanco Ventilation Turbine Set with Electrical Ventilator combines a BEB14 ventilation turbine with an electrical ventilator with a volume flow rate of 3410 m3/h. When using this system as opposed to a central fully-electric ventilator you’ll save 90% of your operating costs and inside a year you’ll make back the cost of this product. This turbine is also maintenance free as it’s constructed of aluminium, which doesn’t rust. As well as this the product prevents a reverse draft so odours from other apartments will not be able to enter other apartments, it will all be properly ventilated. Central electric ventilators are often noisy and can be turned all building-wide at all hours of the day or night by one tenant, causing issues amongst neighbours and spiralling operating costs. By switching to this Lomanco product you can individually vent apartments/units whenever is necessary without the entire system switching on or needing electricity.
