Fan-powered reusable full-face mask respirator

Fan-powered reusable full-face mask respirator​​​

General information

  • They are supplied in different shapes and sizes.
  • They have inlet and outlet valves which must be in good condition.
  • These respirators may be worn continuously for more than one hour.
  • They can be cleaned and used many times, as recommended by the manufacturer.
  • In general, reusable full-face respirators are made from flexible rubber or silicone material.
  • Full face masks cover the whole area of the face. Some makes are fitted with an inner half mask.
  • 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.
  • 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.
  • 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).

Do

  • Fit the straps as recommended.
  • Select the right size mask for each wearer.
  • Choose respirators that have a flow indicator.
  • Always fit two identical filters to a twin filter mask.
  • Change used filters at the manufacturer's recommended frequency.
  • 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.
  • Ensure you have the right filter(s) for the substance - particle or gas or vapour, or the required combination.

Don't

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