3M 4251+ Half mask respirator FFA1P2 R D EN 405 DIN 405

The 3M™ maintenance-free 4251+ half mask offers you effective respiratory protection as a user-friendly complete mask. The new, improved exhalation valve reduces breathing resistance during exhalation, reduces heat and moisture formation, making breathing easier, especially in hot and humid working environments.

Our half masks series 4000+ has a soft, skin-friendly, silicone-free face sealing. The filter class FFA1P2 R D protects against many of the common organic gases, vapors and particles in the industrial environment.

The light, well-balanced design with the integrated, maintenance-free filter elements provides a good peripheral view.

The integrated filter elements are maintenance-free. You can use the half mask until a change according to the filter change plan is pending or the filter elements are saturated. Then dispose of them properly.

The comfortable straps with adjustable head holder offer a secure fit and adapts to different head shapes and sizes. The flat design does not restrict your field of view and the two large active carbon filters provide a low breathing resistance.

The filter class FFA1P2 R D protects against organic gases and vapors up to 30 times the limit (boiling point above 65 degrees Celsius) and against particles up to 10 times the limit.

A resealable bag for hygienic storage and transport is included in the delivery.

*The exhalation resistance of the 3M™ 4000+ half mask series>> was reduced by 30% at 120 l/min and by 35% at 160 l/min as compared to the previous 3M™ 4000 series. Results were measured in 2017 by 3M under laboratory conditions. Respiratory rates are just one example.
