Low-Profile Respirators

Designed to fit easily under welding helmets, this respirator has a large surface area, which minimizes breathing resistance. Replace the filter when breathing through these respirators becomes difficult. Separate intake and outflow channels keep exhaled air from saturating the filter, so air remains cool and dry.

Fitted with an N99 filter, this respirator filters out 99% of solid particles. It is not oil resistant.

Spark-Resistant Disposable Respirators

Adjustable Nosepiece

Adjustable Nosepiece and Face Seal

Often worn for welding and grinding, these respirators resist igniting from flying sparks and flames. Made of flame-retardant polyester, they meet ASTM D2859 standards for flame resistance. As you breathe in, they filter out metal fumes, harmful particles, and other contaminants. Throw them out when breathing becomes difficult or if they’re damaged or dirty. Rated N95, these respirators filter out 95% of solid particles. N95 respirators aren’t oil resistant. They’re the best choice for short-term use in areas with low levels of contaminants. To prevent your mask from filling with hot, humid air, they have an exhale valve that quickly releases your breath.

To achieve the N95 filter rating, you'll need a respirator that creates a tight seal with your face to prevent contaminants from entering through the sides. Pinch the adjustable nosepiece to tighten the fit over your nose. Choose the respirator that matches the style you have been fitted for.

Respirators with a face seal reduce gaps between the mask and your face, so they keep out contaminants better than standard respirators.

Powered Air-Purifying Respirators

These mobile respirators filter contaminants to deliver breathable air without the need for an air line connection. The pump sits on your back to allow unrestricted movement, so these respirators are often used in welding, painting, and pharmaceutical applications. Made of Tychem 2000 (formerly known as Tychem QC), these hood respirators have two layers: an outer bib for overspray protection and an inner bib that tucks into your clothing for splash protection. Respirators include a rechargeable lithium ion (Li-Ion) battery that provides approximately four hours of continuous use when fully charged. Respirators have a ratchet suspension that adjusts with an easy-turn knob.

Welding Helmets

Providing greater safety while welding than face shields, these helmets have an outer filter lens cover for protection from scratches and weld spatter. All helmets have a ratchet adjustment with an easy-turn knob.

Helmets with a flip-up lens let you expose a viewing lens.

Nylon helmets are lighter weight than fiberglass helmets.

Fiberglass helmets provide superior heat resistance.

Leather helmets are flexible, so they’re easy to maneuver in tight spots.

Style B and D helmets have an extended forehead that offers more overhead protection.

Welding Face Masks

Nomex Aramid

PBI

These face masks are double-layered to protect your head from radiant heat, flames, and welding sparks. They are designed to meet NFPA 1971 standards for structural firefighting. Check the PPE category and minimum arc rating provided for your workplace, and then select all required clothing and personal protective equipment to meet the minimum arc rating. Arc rating measures a garment’s ability to insulate the wearer from burns; the higher the arc rating, the greater the flame resistance.

Nomex aramid is heavier than PBI, yet breathable and moisture wicking. They meet NFPA 70E standards for protection against electrical arc flashes for personal protection equipment (PPE) category 2. This is the most common PPE category for standard industrial applications.

PBI is lightweight and provides better wear- and heat-resistance than Nomex.
