Welding Fume & Vapour Respirator — HFM-W Welding Half Face Mask PAPR Gas System | AYO WX
The system includes everything to get started, but to save the trouble of buying new filters soon, we recommend buying some packs of spare filters to suit your working conditions and frequency of use.
Includes one AYO WX HEPA Filter – Gas + one gas cartridge of your choice.
No hose, no belt welding gas PAPR System for welding fume, organic vapours and other toxic gases
AYO WX HFM-W Gas is a welding half face mask PAPR for welding fumes plus gases and vapours. Its low-profile mask fits under most common welding helmets. Its Gas Filter Unit combines a gas cartridge with a HEPA particulate filter.
Choose the gas cartridge that matches the gases in your work:
A2-EU cartridge: protects against Type A organic gases and vapours, such as solvents, with a boiling point above 65 °C. It has the higher organic vapour capacity (Class 2), so it is the choice for solvent work.
A1B1E1K1-EU cartridge: protects against Type A organic gases and vapours, Type B inorganic gases such as chlorine and hydrogen sulphide, Type E acid gases such as sulphur dioxide, and Type K ammonia and certain amines. Choose it when any of these gases are present, on their own or with solvents.
The HEPA Filter in the Gas Filter Unit protects against airborne particulates.
