Inline Exhaust Fan

What is an inline exhaust fan?

Within Lexington Apartments, your unit’s wet areas [ensuite, bathroom & laundry] are serviced by an inline exhaust fan. The inline exhaust fan system uses ductwork inside your ceiling to vent air from the wet areas to an external wall vent. With an inline fan it is possible to create multiple inlets by using a Y Junction, thus servicing multiple wet areas with a single inline exhaust fan. An inline fan does not sit directly on the plasterboard or ceiling, instead it is typically located inside the roof space a little bit further away from the ceiling vents in the wet areas. This means the noise of the inline exhaust fan is not intrusive. The capacity of your inline fan has been chosen to meet the suggested rate of room air changes per hour which is based on the Australian Building Codes as a guideline and considers reasonable and standard situations and expectations. As an indication, the suggested air changes per hour is:

Location Air Changes Per Hour

Bathroom [toilet only] 6 – 15

Bathroom with a shower 15 – 25

Laundry [no Dryer] 6 – 15

Laundry [with Dryer] 15 – 25

In certain circumstances your inline exhaust fan may not by itself provide a complete ventilation solution for a particular area. Other factors may contribute to achieving a desired ventilation solution, which can include but is not limited to the climate, the materials in the room [e.g. tiles, windows etc], whether there is dampness or excessive humidity issues, whether enough air is coming in or whether there is good cross ventilation.

Testing your inline exhaust fan 

Your inline exhaust fan will activate once you turn on the light in one of the wet areas and will remain on until the light is switched off. When operating, your inline exhaust fan should create enough suction at the ceiling vent to hold in place a piece of tissue paper which is large enough to cover the majority of the ceiling vent. 

Maintenance of your inline exhaust fan

It is an Owner’s responsibility to keep the ceiling vent clear of dust. Therefore, it is advisable to conduct regular cleaning of the ceiling vent. Using a suitable step ladder, you should be able unscrew [anti-clockwise] and remove the central part of the ceiling vent to access &

remove any build-up of dust.

Responsibility for service costs of your inline exhaust fan

Should you have any questions or concerns that your inline exhaust fan is not operating as expected, please contact Lexington’s Building Manager in the first instance to discuss. If you choose to call a technician and the cause of the issue is not a failure of your inline exhaust fan motor or due to damaged ductwork, you may be liable for the cost of the technician.
