Weidmüller includes four different design types in its range: standard filter fans, EMC-version filter fans to meet higher demands in terms of the attenuation of electromagnetic fields, roof opening filters and Slim Line filter fans with a particularly low-profile build-in height. All versions are available with grey and black enclosures. A 4-corner snap-fit mechanism enables rapid and tool-free installation. All design types are available in different sizes and with different power levels. The smallest device has a volumetric flow of 25 m3/h, an edge length of just 109 mm and a depth of 62 mm. The most powerful device offers a volumetric flow of 925 m3/h. It has an edge length of 320 mm and a depth of 157 mm. With the design of all the filter fans, attention was paid to energy-efficiency and a long working life. If one fan should fail, it can very easily be swapped out separately. This is possible thanks to the cable gland installation and the use of a terminal block for the electrical connection.
Weidmüller builds its filter fans with low energy-consumption twinned with high air flow levels, so that they can fulfil their task accurately and economically. In addition, only high-quality filters from filter class G3 and G4 and/or with IP54 and IP55 ratings are used. Through its enlarged surface, the working life of the folded filter mat used in the IP55 version is extended by up to 300%, in comparison to traditional filter mats. The filter mats can be swapped out quickly and simply through an easy-to-use hinged cover.
A range of matched accessories complements the programme of fans. There is, for example, a selection of heating and control elements that reliably prevent the build-up of condensation in the control cabinet. The heating elements are designed for a 100V to 250V power supply and as an option, are available with a thermostat. The programme also includes separate thermostats, with a switching range from -20°C to +40°C, which can control both heating elements and filter fans. The range of available control technology elements is completed by a hygrostat with an adjustable tripping value of from 40% to 90% relative humidity. In this way, filter fans and heating elements only work when cooling or heating is actually required. Energy-efficiency can be increased and costs can be decreased by the needs-based usage of thermostats and hygrostats.
Now, there is nothing standing in the way of achieving perfect climatic conditions in the control cabinet.
