Lomanco’s ENERGO EVL and BEB14 vent turbine set combines a 14 inch diameter Lomanco wind-powered externally braced vent turbine with an electric ventilator. The ENERGO EVL 1400 connects to the vent turbine to give an extra boost in adverse weather conditions or when there’s no wind present. This ensures that your building is being ventilated whatever the weather. Great for ventilating roofs, attics, and even apartment buildings, the electric ventilator features overload protection so that there’s no damage to the turbine when switching between electric and wind-powered. Another key feature of the electric ventilator is its low energy use. It has a volumetric flow rate of 1400 m3/h but uses very little electricity, minimising any strain on your bills. You can switch from wind power to electric power manually or automatically and you’re also able to purchase optional sensors that can monitor humidity, CO2, and other indicators. When the sensors detect a given change they can increase or decrease ventilation, switching from wind-powered to electric if you please. This is fantastic for apartment buildings as you could set a timer for when most residents will be cooking to maximise ventilation throughout the building. All Lomanco turbines come with a Lifetime Transferable Warranty, which is transferable from the original owner to subsequent owners - 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 ENERGO EVL & BEB14 Properties Volumetric flow rate: 1400 m3/h
