ACCESSORIES & ADDITIONAL SECTIONS 8 ASSEMBLY AND INSTALLATION SUGGESTIONS 10 marIk INSTALLATION CONTROLS Changes reserved SUSTAINABLE AND EFFICIENT AIR EXTRACTION Mark MDV Blue roof fan is suitable for extracting air from buildings and features the latest developments in the field of fans, including the efficient EC-technology. This enables the MDV Blue to guarantee a very low power consumption combined with excellent performance. The MDV Blue roof fan is available in various sizes and air capacities ranging from 300 m3/h to 15.000 m3/h. The roof fan is equipped with a centrifugal fan, the casing...

EU 1253/2014 This standard is adopted by the European Parliament in which demands are made regarding the eco-design of ventilation units. Air handling units (supply and exhaust units) with an air flow higher than 1000 m3/h must be fitted with adjustable heat recovery with a prescribed minimum efficiency. In this configuration, the fans need to be supplied with speed control so that the SFP (specific fan power) limits are not exceeded. With these new requirements, the European Commission aims to significantly reduce the maximum power consumption of ventilation systems in buildings. Mark's MDV...

MODBUS The built-in Modbus communication in the MDV Blue EC enables the easy controlling and remote reading via the building management system. Information such as faults and history are easy to read. The MDV Blue AC can be controlled through a seperate Modbus communication. POTENTIOMETER CONTROL In combination with the MDV Blue EC, it is possible to issue a 0-10V signal by means of a potentiometer to control the fan in a variable manner.
