ABSTRACT:
A housing for a powered air purifying respirator blower unit is provided. The housing comprises first and second major faces which are spaced from each other, and a top wall, side walls, and bottom wall connecting the major faces along their peripheries. The first and second major faces and the top wall, side walls, and bottom wall enclose therebetween an air chamber. An air inlet and an air outlet are in communication with the air chamber, the air outlet being proximate the top wall. A support base is proximate the air outlet and connected to the first major face. A pommel-like strap support member protrudes from the support base in a direction away from the second major face and comprises a lower exterior support surface which is adapted to support a carrying strap thereon such that the carrying strap can extend away from the housing at a variety of angles. The air outlet opens through the top of the pommel-like member. The housing includes a means for retaining a carrying strap on the pommel-like member. Also provided is a powered air purifying respirator comprising such a housing.
