Module Filter Cover

Failure of computer installations in hostile environments is common because of the corrosion of the electronic components. The present arrangement provides a low cost, but practical, solution to this corrosion problem in the hostile environment.

Fans 10 are installed in the cover for the modules, as shown. The electrical wiring that is required is connected through the left hand corner of the cover to a male half 13 of the electrical connector. The female half 14 of the connector is installed in the frame. The filter element 15 is made up of a particulate filter element 16 and a second filter layer of gaseous silver sacrificial element 17. The filter 15 fits over the air inlet louver pattern.

The gaseous silver sacrificial element is optional and is installed usually in the industries where S0(2) (sulphur dioxide) content in the air is excessive. The male half connector 13 not only provides electrical connections to the fans 10 in the module filter cover 12, but the connector also provides physical strength which also holds the cover on the left hand side. Other latches (not shown) can be provided for physical mounting of the cover to the module.

Blowing the air into the unit provides a positive pressure within the unit, thereby preventing leakage of environmental air into the unit without filtering.
