Abstract
A filter adaptor is provided for a respirator that allows the respirator to accommodate filters that have a different connection interface than the filter connection on the respirator. The adaptor includes a body having a first surface and an opposite second surface and defines a through hole. Mask locking tabs on the first surface engage with a complementary bayonet attachment the respirator. A first wall on the first surface and an inlet port gasket thereon nests within a complementary inlet port on the respirator to form an air-tight seal between the first wall and the inlet port. A valve ring on the first surface of the body engages an inlet valve on the respirator. A second wall on the second surface includes filter locking tabs that engage with a complementary filter opening of a filter. A filter gasket around the second wall forms an air-tight seal between the filter opening and the adaptor.
