Abstract

A respirator (1) has a fan (5) operable at two speeds to permit the respirator to be used either with a first type of filter element (3G) for removing gases (or vapours) or with a second type of filter element (3P) for removing particulate matter. The speed of the fan is controlled by the position of a resiliently biased switch (10). One type of filter element (3G or 3P) is adapted to depress the switch so that the fan runs at one speed whereas the other type of filter element (3P or 3G) does not engage the switch so that the fan runs at the other speed.
