The 3M 7100009686 is a single lens assembly replacement designed for use with 3M Ultimate FX Full Facepiece Reusable Respirators. This replacement lens restores optical clarity and structural integrity to the full facepiece assembly, ensuring a proper seal and unobstructed field of vision for the wearer. Weighing 3.27 pounds, the lens is engineered to fit precisely within the facepiece frame without modification. Industrial hygienists, safety professionals, and respirator program administrators rely on OEM replacement lenses to maintain equipment to manufacturer specifications rather than replacing the entire facepiece unit.
This lens replacement is intended for use in environments where full facepiece respirator protection is required, including industrial, chemical handling, confined space, and hazardous material applications. It is suitable for residential and commercial environments wherever the 3M Ultimate FX Full Facepiece Respirator series is deployed. Installers and safety technicians performing routine respirator maintenance will find this part essential for extending the service life of the facepiece assembly.
Designed for use with 3M Ultimate FX Full Facepiece Reusable Respirators FF-401, FF-402, and FF-403.
Lens replacement should be performed by a qualified safety technician or respirator program administrator following the manufacturer's maintenance guidelines. Before beginning any lens swap, ensure the respirator is removed from service and fully cleaned per applicable OSHA and NIOSH protocols. Do not use the facepiece in service until the replacement lens is fully seated and the assembly passes a positive and negative pressure user seal check. Proper fit testing should be conducted after any significant maintenance to the facepiece assembly.
