Organic Vapour Respirator — HFM Half Face Mask PAPR Gas System | AYO WX
Choose your system:
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 PAPR Gas System for organic vapours, other toxic gases and dust
AYO WX HFM Gas is a hose-free organic vapour respirator that also protects against other toxic gases. 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.
The main unit sits around the neck with no hose and no belt, so it is worn much like a non-powered half mask while breath-responsive airflow does the work.
Australia’s workplace exposure limits for many solvents fall on 1 December 2026. See what changes in our Workplace Exposure Limits 2026 guide.
