 Place the extractor fan at the top of the cabinet and the air intake at the
bottom. See previous figure.
 To have a filter in the air input. The fan should also have a filter.
 Decrease the air intake speed from the outside by making the air input
window larger than that of the fan. The required power and air flow de-
pends on the power installed.
 nstall the DDS system as far away as possible from air inputs and out-
puts.
 Carry out periodic maintenance on air filters.
Use the following suggestions to minimize the maintenance of this type of
cooling systems and the contamination of the electrical cabinet:
 Set the fan to work only when the inside temperature of the electrical
cabinet exceeds the predetermined limit (for example 45 °C). This will
decrease its running time and the flow of the incoming air while increas-
ing the lifespan of the fan. The cost of this solution is minimal using a bi-
metal type thermostat or controlling it by using one of the outputs of the
PLC or CNC.
Install a fan whose speed varies depending on the air temperature. This
type of fans have an NTC sensor either integrated into it or supplied as an
accessory by the fan manufacturer.
