Design of an Adapter for Air Outlet Filter on the M431 Chemical Agent Detector

摘要

An adapter has been developed to allow an air filter to be easily attached andremoved from the exhaust port of the M43A1 Chemical Agent Detector. The adapter is to replace a threaded coupling presently in use, provide reliable filter retention, and ease of attachment and removal. The adapter was designed for low-cost production in quantities of 100,000. Three design alternatives are presented. Production, testing, and evaluation of each design is described. An ultrasonically assembled two-part design with an internal Nitrile )-ring is selected. The components are injection molded of Acetal Resin. Keywords: Chemical agent detector, Adapter design. (JS)
