ABSTRACT:
A gas sampling device includes a tubular ceramic filter element sealably mounted to a mounting plate and a locking member which secures the filter element to the mounting plate. The locking member includes a filter element cleaning nozzle which directs high velocity pulses of a cleaning gas into the filter element. An annular passageway surrounds the cleaning nozzle and carries gas from the filter element to an outlet port spaced a substantial distance from the open end of the nozzle.
