To maintain the exterior of the dryer

Hand dryers should be regularly cleaned as part of your washroom cleaning schedule.

  • The exterior of the dryer, including the automatic controller lens and the air inlet grille, should be cleaned with a damp cloth
  • DO NOT use aggressive cleaners or solvents as they can permanently damage the surface.
  • A proprietary furniture polish can be used, however performing a test on a small area is recommended
  • Airdri dryers are drip proof (IP21 or better, see rating label), DO NOT allow liquids to enter the unit


To maintain the interior of the dryer

Interior hand dryer cleaning and maintenance must be undertaken by a competent person every six months or more frequently in a dusty/high usage environment.

  • Turn off all power to the dryer
  • Remove the cover
  • Using a small brush or vacuum, carefully clean out the build-up of dust and lint
  • Check the length of the motor brushes. If less than ½” (12.7mm), replace. Check that motor brushes are installed correctly and that the brushes are worn evenly
  • Clean controller lens
  • Replace cover
  • Turn power back on
  • Test operation of unit
