Fan-and-Filter Units

Rittal India offers TopTherm fan-and-filter units, a powerful tool against hotspots. This completely new generation of fan-and-filter units are the first in the world to use diagonal technology. When installed, the innovation ensures a much higher air throughput for improved ventilation in enclosures and housings. Other convincing advantages are the simple, tool-free assembly, the ease of maintenance, and an attractive design. When fan-and-filter units demanded large volume air flows combined with a flat design, axial fans were used. On the other hand, when greater pressure stability was needed, radial fans were chosen. Now, Rittal is combining the technical advantages of both systems. With its new TopTherm fan-and-filter units, the manufacturer has created an intelligent synthesis of radial and axial fan technologies that meets all the specified requirements. In addition to the flat design, the key benefits are the steeper curve and the higher pressure saddle. This results in higher pressure stability and when installed under operating conditions – a constant air flow over a wide area. This in turn means an increased operating life for the filter mats without having to settle for any loss of power in return. Through completely tool-free assembly, the fan-and-filter units can be simply mounted and the air flow direction can be quickly changed. Electrical connections can be made easily and maintenance, including filter mat replacement, is conducted without a hitch. A new release mechanism lets the louvered grille fold down forwards during maintenance work, snapping into position at an opening angle of around 70°. TopTherm fan-and-filter units are available in an extended range of output categories, from 20 m3/h to 900 m3/h (previously 700 m3/h). There is also a choice of 24 V (DC) or 115 V, 230 V and 400 V 3-phase (AC, 50/60 Hz) supply voltages. In addition to the standard fan-and-filter units, EMC fan-and-filter systems are also available. A so-called “EcoComfort” is currently planned.
