Communication cabinet and a method for dust removal of communications cabinet filters

Abstract

A communication cabinet, that includes: at least one fan, adapted to rotate at a first direction during a first period and to rotate at a second opposing direction during a second period; a controller, adapted to control the at least one fan; and at least one filter positioned to prevent dust from entering the communication cabinet and to allow air to exit the communication cabinet such as to remove dust from the filter during the second period. A method for dust removal from a filter, the method includes: providing communication cabinet that comprises the filter, whereas the filter is positioned so as to prevent dust from entering the communication cabinet; rotating at least one fan at a first direction during a first period such as to cool at least one communication circuit installed within the communication cabinet; and rotating the at least one fan at a second opposing direction during a second period such as to remove dust from the at least one filter.

1 . A communication cabinet, comprising: 
 at least one fan, adapted to rotate at a first direction during a first period and to rotate at a second opposing direction during a second period;    a controller, adapted to control the at least one fan and    at least one filter positioned to prevent dust from entering the communication cabinet during a first period and to allow air to exit the communication cabinet such as to remove dust from the filter during the second period.    
   
   
       2 . The communication cabinet of  claim 1  wherein the first period is substantially longer than the second period.  
   
   
       3 . The communication cabinet of  claim 1  wherein at least one fan is positioned such as to force air from a low portion of the communication chamber to a high portion of the communication chamber during the first period.  
   
   
       4 . A method for dust removal from a filter comprising: 
 providing communication cabinet that comprises the filter, whereas the filter is positioned such as to prevent dust from entering the communication cabinet;    rotating at least one fan at a first direction during a first period such as to cool at least one communication circuit installed within the communication cabinet;    rotating the at least one fan at a second opposing direction during a second period such as to remove dust from the at least one filter.    
   
   
       5 . The method of  claim 4  wherein the first period is substantially longer than the second period.  
   
   
       6 . The method of  claim 4  wherein rotating of at least one fan during a first period comprises forcing air from a low portion of the communication chamber to a high portion of the communication chamber.
