Cooling Power Electronics

Beyond basic functionality, fan/filter units such as the Axair ‘FPF’ range now have many other useful attributes such as their availability in both colours RAL 7032 and 7035, a variety of standard voltages both ac and dc, enhanced protection to IP55 standards, choice of airflow direction, and EMC/RFI screening. From an installation perspective the units are now supplied in a low profile ‘click-fit’ design with an attractive and practical chevron louvre.



‘FPF’ fan/filter assemblies are now stocked by Axair Fans UK Ltd in 10 basic models with 5 sizes of louvre ranging from 105 to 325mm square, with maximum flow rates to 650 cu.m/h.



Axair Fans also offers Fandis new generation of “FF” fan filter units dedicated for electrical enclosures and control panels.



The fixation system has been improved in order to accommodate thicker steel plates, up to 8mm, and still offering the fast assembly ‘click-fit’ system with elastic hooks. The filter media is more easily accessible by removing the front cover by hand without the need for tools. All other maintenance operations are only possible from inside the enclosure. The improved sealing gasket is fitted between the filter unit and the enclosure, and is now completely hidden. Like the current range of “FPF” filter fans, the new “FF” range is available in both colours RAL 7032 or 7035, a choice of voltages ac or dc, enhanced protection to IP55 standards, and choice of airflow direction.



Where filtration is not integrated with the fan, there is an enormous range of axial and centrifugal fans to choose from with airflow rates and pressure developments up to and beyond the limits envisaged for enclosure ventilation.



Axair Fans UK Ltd also offers an extensive range of thermal management equipment for electronic and electrical enclosures, including standard and changeover thermostats, hygrostats, PTC heaters and lights.
