A corona generating device including a housing for receiving a replaceable shield having a base shield element and a pair of side shield elements, wherein each of the shield elements are mounted in the housing in a configuration so as to partially enclose a corona generating electrode. The housing is provided with pivotable side panels which each further include a pair of lip elements forming a channel for slidably receiving a respective side shield element. The side panels are pivoted about a pivot axis for facilitating the service and replacement of the side shield elements to thereby prolong the operational life of the corona generating device.
