Sellstrom 37701 Replacement Window for 301 Series

Sellstrom 37701 Replacement Window for 301 Series & Univeral Face Shield Review

The Sellstrom 37701 is an ANSI Z87.1-compliant chemical splash face shield designed for chemical handling, laboratory, and liquid splash environments. Constructed from impact-resistant polycarbonate, it provides full-face coverage from brow to below the chin line — protecting the face, cheeks, and jaw from hazards that safety glasses and goggles cannot address alone. It is designed for use with compatible face shield headgear assemblies. REPLACEMENT – Replacement window for Sellstrom 301 Series face shields and various other brand crowns.

Construction and Materials

The lens window is constructed from injection-molded polycarbonate — a thermoplastic known for high impact resistance (rated superior to acetate or propionate in ANSI Z87.1 high-impact testing), optical clarity, and resistance to surface crazing under UV exposure. This listing is a replacement lens window compatible with standard face shield headgear frames. Replacement lenses allow continued use of existing headgear assemblies without replacing the full unit when the lens becomes scratched or degraded. FIT – Universal hole pattern enables these windows to fit in a wide variety of face shields. The lens window extends coverage across the full frontal face profile, with side flanges or curved geometry providing lateral protection beyond the direct forward field. The construction meets or exceeds ANSI Z87.1 high-velocity impact requirements.

Compliance and Ratings

Rated to ANSI Z87.1 and OSHA 1910.133 for chemical splash and liquid hazard environments. ANSI/ISEA Z87.1 is the governing standard for eye and face protective devices in U.S. workplaces; OSHA 29 CFR 1910.133 mandates its use in workplace environments where eye or face hazards exist. For compliance programs, face shields should be used as part of a layered eye and face protection strategy per OSHA PPE hierarchy requirements. COMFORT – Premium clear, V-shaped polycarbonate window curves naturally to fit facial contours ensuring reliable protection from splashes, particles and flying debris.

Performance

In chemical handling environments, full-face coverage extends protection below the chin line and to the peripheral face area — coverage that safety glasses and goggles alone do not provide. Face shields used with chemical hazards should be worn over appropriate eye protection (goggles or safety glasses) per OSHA guidelines, not as standalone protection. CERTIFIED – Meets ANSI Z87.1+ and CSA Z94.3 standards. Maintaining lens cleanliness and replacing lenses when scratched preserves visibility quality critical for precision work.

Strengths

• Polycarbonate lens provides ANSI Z87.1 impact-rated protection for chemical splash applications
• Optical-grade lens material maintains visibility clarity without distortion at working distances
• Compatible with standard face shield headgear assemblies for flexible deployment
• Adjustable headgear fits most adult head sizes for crew-level deployment
• Full-face coverage from brow to below the chin protects areas not covered by eyewear alone
• Single-unit design simplifies inventory and procurement

Limitations

• Face shields do not provide complete eye protection as standalone devices against chemical splash or fine particle hazards — OSHA 1910.133 requires appropriate safety glasses or safety goggles underneath the face shield in chemical and grinding environments
• Lens scratching from abrasive contact degrades optical clarity over time; replacement lenses should be sourced when transmission quality decreases
• One-size-fits-most headgear may not accommodate all head sizes or hard hat combinations; verify compatibility with the helmet platform before crew-scale procurement

Recommended Use Cases

Chemical mixing and transfer operations; laboratory handling of acids, caustics, and solvents; pharmaceutical manufacturing; janitorial and cleaning with caustic products; paint spray operations. This face shield is appropriate for any OSHA-regulated workplace where face and eye hazard assessments document a risk requiring face shield-level protection.

Verdict

The Sellstrom 37701 face shield delivers ANSI Z87.1-compliant protection for chemical splash applications in a polycarbonate construction suited for industrial and occupational environments. Buyers should confirm the specific model matches their headgear platform and application requirements before crew-scale procurement.
