Ecosmart external & internal twin fans. All internal chamber surfaces are acoustically treated. Outlet grilles are positioned on opposite sides of the fan casing to prevent wind pressures effecting fan performance. Fan assemblies incorporate forward curved centrifugal impellers belt driven by BS5000 motors fitted with airflow fail monitors. Fans are suitable for operation in ambient temperatures up to 40°C.
The fan should be fitted with an Ecosmart control together with an inverter speed controller. Ecosmart Constant Pressure fans incorporate the means to sense pressure within the system inlet ductwork and to vary the fan speed so as to maintain the appropriate pressure drop across the variable orifice room extract terminals.
The fan shall have the following energy saving functions integrally mounted within the fan unit on a purpose made PCB, all components pre-wired by the manufacturer: integral maximum and minimum speed adjustment/setting; integral auto-changeover/duty share, fans changeover every 12 hours of run time; integral adjustable run on timer; integral BMS interfaces, 0-10v and volt free failure indication.
Components will be pre-wired and fitted by the manufacturer: Please refer to catalogue pages for full Consultant specification.
