Overview

• The 3M 7502 comes from the 7500 Series, the most comfortable tier of 3M half facepieces, offered here in size medium. The facepiece is advanced silicone that gives a softer feel on the face and greater durability than conventional materials, with a unique adjustment design that reduces pressure points — the factors that actually determine whether a worker keeps the respirator on for a full shift. The Cool Flow™ exhalation valve makes a tangible difference in hot conditions, making exhalation easier and cutting heat and moisture build-up inside the respirator. The four-point head harness works in two modes: standard, and drop-down, which lets the respirator be lowered from the face during a pause without removing the hard hat. The solid exhalation valve cover directs exhaled breath and moisture downward, protecting the valve area from debris and making cleaning easier. Cartridges attach through a bayonet connection compatible with 6000 Series cartridges, 2000, 2200, 5000 and 7000 Series filters, and dual airline systems. The respirator is NIOSH approved with an Assigned Protection Factor of 10, is grey/blue, is supplied one per bag, and has spare parts and a head harness assembly available. Available through Al-Najma Al-Wataniyah with guaranteed quality and fast delivery across Riyadh, Dammam, and all KSA regions.

Documentation & Standards

• The respirator is approved by NIOSH, the US federal agency responsible for testing and approving respiratory protective devices, and its head harness carries the CE mark with notified body number 2797 and the European standard reference EN 140:1998 for half masks — combining American and European approval in one product, which eases acceptance in projects citing either reference. An Assigned Protection Factor of 10 means a properly fitted respirator reduces the contaminant concentration reaching the wearer to one tenth of the surrounding air. Actual protection is delivered by the complete assembly: the facepiece together with the 3M cartridge or filter matched to the contaminant. Product documentation and approval certificates can be provided on request to support project files. We also recommend verifying SASO/SABER requirements for respiratory protective equipment before supply.
• Additional reference standards for the Saudi market:
• NIOSH 42 CFR Part 84 (respirator approval in the United States)
• EN 140:1998 (half masks and quarter masks) · EN 14387 (gas filters) · EN 143 (particle filters)
• OSHA 29 CFR 1910.134 (respiratory protection programmes, fit testing and assigned protection factors)

Frequently Asked Questions

Q1: What does the silicone facepiece add?

• Silicone is softer on the face than conventional materials, reducing pressure and raising comfort over long shifts, and it is more durable and easier to clean, keeping its flexibility through repeated use — the factors that keep a worker wearing the respirator.

Q2: What does the Cool Flow valve do?

• It is an exhalation valve designed to make breathing out easier and to cut heat and moisture build-up inside the respirator, giving a cooler, drier feel — a tangible difference in hot climates and physically demanding work.

Q3: What is the drop-down mode for?

• It lets the respirator be lowered from the face during a pause and hang around the neck without removing the hard hat or readjusting the harness, saving time and preserving the verified fit.

Q4: Does the respirator facepiece alone protect against gases and dust?

• The respirator body is the facepiece; actual protection comes from the cartridge or filter fitted to it for the contaminant: particulate filters for dust and fume, gas and vapour cartridges for solvents, and combination cartridges for both. Our sales team can help you choose.

Q5: Is delivery available to Riyadh, Dammam, and all KSA regions?

• Yes, supply is available across all KSA regions with bulk quantities available for B2B projects and equipping full work crews.
