Filters in P-10 production hoods

摘要

This paper addresses the reported problem of insufficient air flow through the Fiberglas filters for the air inlets in P-10 production hoods. Since it appears that the replacement of the contemplated filters with either louvers or grilles will not impose any forseen difficulties and will definitely assist in the ventilation design, this substitution has been accepted. Air flow through the grilles or louvers is to be designed to attain a minimum lineal velocity of 200 fpm through the openings.
