Deep Cleaning of Bathroom Extraction Systems – Do you require this service?
How we can help you?
The issues that COVID have brought upon the world have also raised the profile of not only air supply systems through commercial buildings but also the extraction systems covering bathrooms and toilets especially within Hotels.
How does the deep cleaning of bathroom extraction systems work?
In many ways, a bathroom exhaust fan is not unlike the ceiling fan you may have in your bedroom – only it operates in the exact opposite way you might expect. Ceiling-mounted bathroom exhaust fans use the principle of suction to draw odours, moisture, and other elements up and out of your bathroom via a vent. The fan then passes that moisture through the ductwork where depending on the style of the hotel if might link into a larger vertical duct run which then goes up to the extraction fan on the roof.
How does the system get cleaned?
Here is the problem – a good cleaning regime by housekeeping will ensure that the small extract fan should be like this which gets a proper wipe regularly and remove any dust within the unit. If they are more thorough, they will undo the silencer and clean out what could be behind it.
However, what happens to the system next – often two rooms systems link into a cupboard on the corridor and therefore there is another area where there is a build up of fluff/dust and poor circulation. As an example, the flexi duct links from the bathroom to the vertical duct riser. Example of what can be found in the flexi duct and vertical riser are illustrated below:
The system can therefore have build-up of fluff/dust within a moisture environment that can not only create mould areas but also block the ducting at various points through the system.
