Abstract

Abstract The design and development of a low cost differential pressure indicator giving continual pressure comparison across the substance of an air filter is described. A hazard warning is given when the differential pressure rises above a pre-set value proportional to significant loss of filter efficiency. The differential pressure indicator affords increased protection against infection associated with the use of suction apparatus and allows a net saving in expenditure by ensuring optimum use of integral air filters.
