Dräger. Addressing both protection and comfort, the X-plore 1700 series of filtering facepiece respirators features CoolSafe filter material and a CoolMax exhalation valve. In combination, the respirator’s filter media keep particles out, while also removing humid exhaled air through the exhalation valve, reducing heat build-up and guiding airflow away from the mask. A continuous looped fabric head harness provides the long-duration user with low breathing resistance, a cooler breathing zone, and enhanced comfort. X-plore 1700 series masks fold flat and are individually packaged for easy storage and handling. 412.787.8383. www.draeger.com.
