Dual Cartridge Filter Retainer
Replacement filter retainer for dual cartridge respirator applications.
Use the #501 retainer with appropriate 3M 6000-series cartridge to hold a pre-filter ahead of the cartridge vapor filter - this combination affords reliable protection against both oil and non-oil based particles, as well as certain dusts and mists.
Applicable for spray painting, lacquering, petrochemical and chemical manufacturing.
Use with pre-filters - 3M Particulate Filter (Sku #37163) or #5P71
