3M Full Mask Respirator FF-400

3M FF-400 Series Full Mask Respirator
This 3M Ultimate FX Respirator is a reusable full-face respirator with soft, silicone nose cup and face seal that offers comfort, durability, and ease of cleaning. 3M FF-400 can be accessorized to operate in two modes: negative pressure air purifying or dual airline supplied air. Use this full face respirator with 2000 or 6000 series 3M cartridges and filters. This respirator incorporates a durable, long-lasting Head Harness with a six-strap configuration for a secure fit. Paint and stain resistant Scotchgard protector lens causes some liquids to bead up on the surface so they can be wiped off easily. Optional lens covers can be purchased for the 3M FF-401, FF-402 and FF-403 respirators and allow the user to work with applications that would otherwise quickly cause the lens to become dirty and render the mask useless.
