Now breathing is easier! Reusable maintenance-free half mask 3MTM, series 4000+. This renewed design of the most popular reusable maintenance-free half mask from 3M makes breathing even easier and is more practical and reliable. Additionally, it features measurable improvements in comfort.

FEATURES

• Facial piece.
• Low profile for better peripheral vision.
• Very lightweight and balanced.
• Made from soft and hypoallergenic material.
• Storage bag for keeping between use periods.
• Filter protector 3M 400 to preserve filters in very dusty or dirty conditions such as spray applications.
• Comfortable and effective protection against organic vapors and hazardous particles.

• The newly improved valve assembly helps reduce exhalation breathing resistance for more comfortable breathing.
• Thanks to the integrated filters and cartridges, it is ready to use and requires no maintenance.
• Snug and soft facial adjustment piece made with textured and hypoallergenic material.
• The centrally located exhalation valve reduces heat and moisture buildup when such conditions arise. FFA2P3 R D protects against organic vapors with a boiling point above 65 °C up to 10 times the occupational exposure limit (OEL) or 5000 ppm (the lower of the two values) and, in the case of particles, up to 20 times the OEL. Includes a resealable bag for hygienic transport and storage.

TECHNICAL DATA

The exhalation breathing resistance of the 3MTM 4000+ mask is reduced by >30% for a maximum exhalation flow of 120 lpm and by >35% for 160 lpm, compared to the 3MTM half masks of the 4000 series. Results measured by 3M in 2017 under laboratory conditions. Breathing rates are shown for example only.

Effectively protect your breathing with the maintenance-free half mask 3M™ 4255+, easy to use and requiring no assembly. The newly improved valve assembly helps reduce exhalation breathing resistance for more comfortable breathing. This mask features a soft, textured, hypoallergenic, silicone-free facial adjustment piece and offers FFA2P3 R D protection against a wide range of organic gases and vapors and combinations of hazardous particles.

It has a lightweight and balanced design, with a centrally located exhalation valve that helps reduce heat and moisture buildup, allowing for more comfortable work in high temperature and humidity conditions. The mask requires no maintenance thanks to its integrated cartridges and filters: simply use the mask, and when the replacement schedule indicates it should be changed or the filters are filled, dispose of it.

Its adjustable head harness fits various head sizes and shapes, and the neck straps are easy to adjust. The discreet design will not obstruct your peripheral vision, and the two large linked carbon filters present low breathing resistance. FFA2P3 R D protects against organic vapors with a boiling point above 65 °C up to 10 times the occupational exposure limit (OEL) or 1000 ppm (the lower of the two values) and, in the case of particles, up to 10 times the OEL. Includes a resealable bag for hygienic transport and storage.

APPLICATIONS

Designed to provide effective protection against most contaminants, whether in gas phase, vapor, or in combination with particles.

• Maintenance-free respirator for spray painting, brush and roller application, as well as for manual sanding and orbital sanding.
• A2 protection against organic gases and vapors, such as those emitted by solvent-based paints, adhesives, and cleaning detergents.*
• The P3 level protects against high levels of fine dust and oil or water-based mists.*
• *This product helps protect against certain organic vapors and gases (boiling point >65 °C) at concentrations up to 10 x OEL (Occupational Exposure Limit) or 5000 ppm (whichever is lower) and particles at concentrations up to 20 x OEL.

STANDARDS

Tested and approved according to European standards: CE mark 0086 (EN 405:2001 + A1:2009 FFA2P3 R D)

The user must be trained in the correct use of the equipment and read and understand the instructions for use. Improper use may result in serious illness or permanent disability.

The spray painting respirator 3M™ 4255 is our hybrid maintenance-free half mask respirator that can be used until it is damaged, clogged, or saturated. It features dual inhalation valves, large linked carbon filters, and a low-resistance exhalation valve that makes breathing more comfortable.
