30 pint dehumidifiers


Mounted on it’s side, secured with special feet that swivel out.  A public toilet installation ducting moisture through an extractor fan.  The extractor fan was in operation when the toilet was occupied but the same vent was use to vent moisture continuously all day and every day when needed.

Note a top cover without a handle can also be obtained if required.


Mounted upside down.  The curved ducting lengths have been used to help avoid dead air spots that can occur if the dehumidifier is placed in a corner of a room or an alcove. In that instance, dry air would circulate over and over in the same area and not be dispersed to the rest of the room.  Two ways to overcome this; either extend the dry air outlet with ducting or add additional fans to help circulate the air around the room being dried.

Example A – Most common installation

Actually, you don’t need to install.  Just put the dehumidifier in a room and vent moisture to the outside even through a slightly opened window

EXAMPLE B simple WALL or CEILING install 

Example c drying mounted out of sight 

The swivel out feet on these models allow then to be anchored to any point with suitable fixings easily.  Ideal for walls, boats, ceilings or vehicles 

Do not treat the dehumidifier as a fan that gives instant, totally dry air

Every time air passes through the DryFan it is dried about 30% and again by 30% for every repeated cycle through the DryFan.
