Fan-and-filter units are ideal for dissipating heat loads cost-
effectively. The prerequisite is that the ambient air must be
relatively clean with a temperature below the desired enclo-
sure internal temperature. The entire range of fan-and-filter
units is now also available with EMC shielding and a range
of rated operating voltages.
