Choosing the right bathroom fan can be confusing, pick the wrong one and you'll be re-painting the ceiling or re-grouting quicker than you think due to mould and moisture. Bathrooms are defined as areas of increased electrical hazard and it is necessary to fit ventilation products that meet a minimum of IPX5 in zone 1 and IPX4 in zone 2. This means that when installed and connected electrically, the product should prevent the ingress of water splashing and remain electrically safe in use. Building Regulations stipulate that a bathroom extractor fan must extract at least 15L/s in a standard domestic bathroom, Most 4 inch models far exceed this minimum requirement, and nowadays the standard is 85m3/hr(23.61l/s)
Ablectrics have been dealing with the biggest names for years. Airflow, Blauberg and Vent Axia are all available from stock and all provide us with the information needed to keep your bathroom moisture free. The majority of fans fitted in bathrooms are wall mounted 4 inch, Most have timers, some have humidity controls. If you want to avoid having a fan on the wall the alternative is a inline fan, these hide in the loft with a run of ducting leading to a small slim round grill on the ceiling(as well as another heading outside). With the fan not being in the room this keeps the noise even to a minimum. Noisy fans are the most common complaint in a bathroom(especially during the night when trying to not wake others), this can be avoided though a number of quiet fans and our most popular ones are the Airflow Quietair QT100T, the Blauberg Calm and the Vent Axia Svara App controlled fan.

Types of Fan
There are a few different types of extractor fan for you to be aware of. The most common are Axial(connected directly through an external wall and are used when the air doesn't need to be moved long distances or Centrifugal(designed for bathrooms that are not close to an external wall and move air longer distances) Axial fans extracted air is forced to move parallel to the shaft about which the blades rotate, Centrifugal fans extract air at right angles to the intake of the fan, and spin the air outwards to the outlet by deflection and centrifugal force producing a higher output.
Classification of zones for your bathroom
There are currently 3 zones in a bathroom and each one needs a different rating:
Zone 0: The interior of the bath or shower tray)not applicable to fans, more for lighting)
Zone 1: The exterior of the bath or shower tray to a height of 2.25 metres above the floor.
Zone 2: Extends to 0.60 metres beyond Zone 1 to a height of 2.25 metres above the floor.
