BLS 4000next B-lock reusable half-mask is a innovative solution for respiratory protection in industrial environments. Thanks to innovative features and ergonomic design, this half-mask provides safety, comfort and ease of use and maintenance.
Lightweight and Comfortable Facepiece
The reduction in the thickness of the oronasal has allowed a 25% reduction in the weight of the half-mask compared to the previous version, making it one of the lightest on the market. Available in two materials: thermoplastic elastomer (BLS 4000next R) and silicone (BLS 4000next S), it offers an optimal fit for different facial types.
