Description

The G1 Air-Purifying Respirator (APR), hereafter referred to as respirator or device, is an air-purifying respirator for use in
atmospheres which are not immediately dangerous to life or health (non-IDLH). Inhaled air is pulled through the air filtration
cartridges/canisters, which contain adsorbents and a filter that removes or neutralizes specific contaminants. Exhaled air is
released through the exhalation valve. This device is intended for applications where it is necessary for users to go into or work
within a hazardous area for a limited time.
For NIOSH approval information, refer to the G1 APR Approval Insert (PN 10160485).

The facepiece is available in three sizes (small, medium, large). The nosecup is
available in three sizes (small, medium, large). The facepiece includes a large lens
to optimize field of view and a mechanical speech diaphragm to enhance speech
communication. When the facepiece is not connected to the APR adapter, an
opening in the facepiece connection lets airflow bypass the inhalation and
exhalation valves, which decreases breathing resistance and further enhances
speech communication. The facepiece includes a broad range of head harness
designs and material options. An optional spectacle kit is available.
