NOR770030M - North 7700 Series Silicone Half Mask Respirator - Medium

The Industry Standard for Comfort and Safety

The North 7700 Series Half Mask Respirator (Model 770030M, Medium) is the benchmark against which all other industrial half masks are measured. For decades, the 7700 Series has been the go-to choice for safety professionals and industrial workers requiring reliable respiratory protection without compromising on comfort. Unlike standard rubber masks, this unit is constructed from 100% medical-grade silicone. This premium material choice offers significant advantages: it is hypoallergenic, preventing the skin irritation often caused by rubber during long shifts, and it is incredibly soft, conforming to the user's facial contours for a secure, leak-free seal.

Designed for versatility, the North 7700 is compatible with the extensive line of North N-Series cartridges and filters (sold separately). Whether your application involves organic vapors, acid gases, ammonia, or particulate matter, this mask can be adapted to suit the hazard. The dual-cartridge design balances the weight evenly across the face and lowers breathing resistance, reducing worker fatigue. Furthermore, the strategic placement of the cartridges ensures a wide field of vision, crucial for maintaining situational awareness in busy industrial environments.

Durability is a key feature of the 770030M. The silicone facepiece is resistant to oxidation and hardening, ensuring a long service life even when exposed to harsh chemicals or extreme temperatures. The mask features a woven strap cradle suspension system that sits comfortably on the crown of the head, providing a secure fit that doesn't slip or require constant readjustment. Maintenance is straightforward; the mask breaks down easily for thorough cleaning and sanitization, making it a cost-effective, long-term solution for personal protective equipment (PPE) programs.

Key Benefits for Industrial Use

• Superior Seal: The variable thickness of the sealing flange ensures a tight fit around the nose bridge and chin.
• Chemical Resistance: Silicone withstands breakdown from oils and chemicals better than TPE or rubber.
• Reduced Dead Air: The internal design minimizes re-breathing of exhaled air, keeping the user cooler.
