North 7700 Series Half Mask Respirator


The North 7700 half mask is the industry standard for comfort, fit and reliability. For over 25 years the North 7700 has proven itself, protecting workers in some of the harshest environments. Why settle for a copy, when you can have the original?

The 7700 Series is the most comfortable and durable half mask available. Its soft, non-allergenic silicone seal provides excellent protection, comfort and fit. The half mask cradle suspension system allows the facepiece to seal evenly on the face without creating pressure points. Its low profile gives workers a wide field of vision and does not interfere with protective eyewear. The low inhalation and exhalation resistance of the 7700 Series makes breathing easier to reduce worker fatigue.


• Silicone facepiece material conforms to facial features and doesn't harden with age. Silicone is easy to clean, extremely durable and resists distortion ensuring a better fit, time after time
• Contoured sealing flange and cradle suspension system eliminates discomfort caused by pressure points on facial nerves. Design of nose area provides excellent comfort and fit
• Minimal dead air space improves worker comfort by limiting re-breathing of exhaled air
• Direct cartridge to facepiece seal minimizes replacement parts and simplifies maintenance
• Three overlapping sizes will comfortably fit most users
• North 7700 Series Half Masks are compatible with all North cartridges, filters and accessories
• Can be adapted to PAPR or Supplied Air
• Only 9 replacement parts – and all parts are replaceable
