7960 P100 Filter Disk Nuisance Organic Vapor.All Moldex Particulate Filters are NIOSH certified. The7950 P100 Particulate Filter Disk has an efficiency levelof 99.97% or greater against both oil and non-oil basedparticulate aerosols. The P100 Particulate Filter issuitable for most welding applications. Use the #7960 P100Filter Disk when nuisance levels of OV/Ozone are present.All Moldex Particulate Filters are NIOSH certified. The7960 P100 Particulate Filter Disks have an efficiency levelof 99.97% or greater against both oil and non-oil basedparticulate aerosols. The #7960 also offers relief fromnuisance levels of OV/Ozone. For contaminants, such asasbestos, lead, inorganic arsenic, cadmium and MDA thatfall under an OSHA substance specific standard requiring aHigh Efficiency Particulate Air (HEPA) filter. Can also beused in applications such as pharmaceutical, battery,nuclear, welding and metal processing. Also for use inenvironments where oil-based particulates are present. P100Particulate filter disks are lighter than traditionalfilter cartridges, allow for wider field of vision becauseof low profile design and are encased in plastic fordurability and rough handling. P100 disks fit under weldinghelmets, are easy twist on/twist off, with bayonet styleattachment, have an efficiency level of 99.97% or greateragainst both oil and non-oil based particulate aerosols.Meets heat and flame resistance in accordance withANSI/ISEA 110-2003 Section 7.11.1. 100% PVC-Free.1/bg, 30bg/cs
