- ... Findings. It is shown that in terms of the similar sorbent volume and dimensions of the outlet of a filtering box with the exhale valve, the increasing filter area reduces considerably the breathing resistance; however, that results in the reduced protective time of a gas respirator. It has been determined that in this case an increased filter area causes nonuniform distribution of the filtration rate over the filter area and, as a result, nonuniform use of the filter sections. A section in front of the outlet experiences the greatest load in terms of sorption of the harmful gases. ...
