The 3MT 4000+ reusable respirator offers you effective respiratory protection as a user-friendly complete mask. The new, improved exhalation valve reduces breathing resistance when exhaling, reduces heat and moisture build-up and thus makes breathing easier, especially in hot and humid work environments.
The 4000+ has a soft, skin-friendly, silicone-free face seal and protects against many common gases, vapors and particles in industrial environments.
The lightweight, balanced design includes a centrally positioned exhalation valve that counteracts heat and moisture build-up, ensuring a comfortable fit even in hot and humid environments.
The integrated filters are maintenance-free. You can use the half mask until it is time to change it according to the filter change schedule or until the filters are saturated. Then dispose of them properly.
The comfortable strap with adjustable headgear offers a secure fit and adapts to different head shapes and sizes. The flat design does not restrict your field of vision, and the two large activated carbon filters ensure low breathing resistance.
Available in four versions (protection levels) .
A resealable bag for hygienic storage and transport is included.
