An improved version of the 2097 P100 filter.
These 2297 P100 filters are structurally re-designed to make breathing easier, while having a longer service life.
They are especially suitable for physically strenuous work environments where P100 filtering is required, and nuisance level organic vapors such as from solvents, degreasers, and resins are present.
Nuisance level refers to concentrations not exceeding OSHA PEL, or applicable government occupational exposure limits - whichever is lower.
The P100 rating indicates an extraordinary 99.97% filtering efficiency - the highest available.
NIOSH approved for environments containing oil and non-oil based particles, as well as dust and mists.
The 2291 particulate filter can be used on any 3M bayonet facepiece when only particulate hazards are present.
In environments where both harmful vapors and particulates exist, the 2291 filter should be mounted on an appropriate 3M organic or chemical vapor cartridge using a 3M 502 adapter, as vapor cartridges alone do not protect against particulates.
• Can be used in applications formerly requiring HEPA-rated respiratory protection
• Suitable for all marine applications such as grinding, sanding, sawing, welding, brazing, torch cutting, soldering, sweeping, and asbestos abatement.
• As required, use with appropriate gas or vapor cartridge
• Chemical absorbent provides relief from nuisance-levels of organic and acid vapors - see product literature for full specifications and restrictions
• Enhanced durability with abrasion resistant netting construction
• Advanced 3 layer design, instead of the traditional 5 layers, but still with P100 rated particle capture — makes breathing much easier
• Flame resistant, flexible filter material resists wetting
• Priced by the pair
Heavy on the technical side...
• Suitable for exposure to lead, asbestos, cadmium, arsenic, 4,4' methylenedianiline (MDA), and pharmaceutical particulates
•Do not use for sandblasting, oxygen deficient atmospheres, or high aerosol concentrations that exceed: a) 10 times the permissible exposure limit (PEL) with a half facepiece, b) 10 times the PEL with a full facepiece qualitatively fit tested, c) 50 times the PEL with a full facepiece quantitatively fit tested, or d) applicable government regulations, whichever is lower
