Fan-powered reusable full-face mask respirator


  • This type uses a motorised fan to pull air through filters. It does not depend on wearer's breathing. However if the motor fails, the wearer can pull air through the filter for exit to a safe place
  • Full face masks cover the whole area of the face. Some makes are fitted with an inner half mask
  • They are supplied in different shapes and sizes
  • In general, reusable full-face respirators are made from flexible rubber or silicone material
  • They can be cleaned and used many times, as recommended by the manufacturer
  • A full-face mask can be used with particle filters, gas filters, vapour filters or a combination of gas, vapour and particle filters as specified by the manufacturer
  • They have inlet and outlet valves which must be in good condition
  • These respirators may be worn continuously for more than one hour
  • These respirators are OK for medium work rate (work involving sustained hand and arm movements, or similar to brisk walking) to heavy work rate (manual work requiring a lot of exertion and energy)


  • Ensure you have the right filter(s) for the substance - particle or gas or vapour, or the required combination
  • Always fit two identical filters to a twin filter mask
  • Change used filters at the manufacturer's recommended frequency
  • Select the right size mask for each wearer
  • Fit-testing for each wearer is required when using this RPE for the first time
  • Ensure that wearers check the RPE fits correctly every time, as recommended by the manufacturer
  • Choose respirators that have a flow indicator
  • Fit the straps as recommended


  • Use in oxygen-deficient atmospheres - e.g. confined spaces
  • Use filters other than those recommended by the manufacturer
  • Store in dirty areas between uses
  • Damage or deform the mask when putting it away
  • Get dirt inside the mask, or clean the mask, straps or filters with solvent
  • Use a damaged respirator - filters, straps, valves
  • Keep working if the fan stops, or if the set flow rate isn't held
  • Use AX filters with this device
  • Make DIY modifications to the RPE
