The difference between axial and inline fans is that inline fans are much more powerful. Are Inline Fans Better?Īn inline fan works similarly to a standard wall mounted axial fan, removing stale or moisture laden air from a room to reduce the risk of mould and damp problems. This means that one inline fan can be used to service multiple rooms or one large room. Multiple Inlet Points - Inline fans can be joined to several inlet/outlets via Y junctions or BTOs. This makes inline fans suited to longer ducting runs in which other standard extractor fans would struggle.Įxtract from Anywhere- Whereas standard axial fans must be installed according to the bathroom zone regulations, the extraction point of an inline fan can be placed anywhere in the bathroom as the fan itself will be installed far enough away from any water sources to be safe. Powerful Extraction & Suitable for Long Ducting Runs- Inline fan motors are more powerful than those in axial fans. There is also a range of silent inline extractor fans on the market which ensure you will not hear the fan running at all. Reduced Noise Levels- Because the fan is located in the roof noise levels are greatly reduced. Kits such as National Ventilation UMDTKLED and Airflow AV100T, provide an attractive and practical feature to the bathroom.

Inline fan grilles can also be combined with lighting. Installing the fan unit outside of the bathroom means that the internal grille can be located anywhere in the bathroom - even directly above a shower. Ducting runs from the ceiling grille to the fan and then from the fan to an external grille which is generally installed discreetly under the eaves of the roof. Inline fans are powerful and very discreet as the fan is installed in the roof or loft space above the bathroom, meaning the only visible evidence is a small flush mounted grille. What is an Inline Fan?Īn inline fan is an extractor fan that is installed directly inside a duct run rather than at the end. Our best budget inline fan is the Envirovent SILMV160/100T a compact, ultra-quiet inline fan with a timer and two-speed motor which provides an extraction rate of up to 180m³/hr.

How Much Electricity Does an Inline Fan Use?Īre Inline Fans Better at Pushing or Pulling?ĭo Bathroom Extractor Fans Need To Vent Outside? Our range of inline extractor fans include models from Vent Axia, Manrose, Envirovent, National Ventilation and Airflow and are compliant with building regulations, making them suitable for new builds or as replacement fans.įor more information about inline fans, please see our FAQs which provide answers to questions such as what size inline fan you require, how to install and which is the best inline fan. Inline fans are generally more powerful and faster at extracting air, with some models also including a mixed flow feature to create a turbine effect, pushing air through the ducting quicker, making these ideal for rooms with heavy shower use, high humidity or with smells that require extraction. All you will see from the ventilated room is the duct where air is extracted from. Inline fans are installed in lofts or ceiling joist space, meaning the mechanics are out of sight and often also in places where fan noise is less of a nuisance. Please drop us a line if you have any specialist requirements.Inline fans are ideal if you are looking for a discreet yet powerful solution to your ventilation requirements. If you have access to roof space, an inline extractor fan system would be quieter and more efficient. The silent fans are particularly popular. Units with integral or inline back draft dampers stop drafts coming back down the ducting and prevent condensation build up within the system.īathroom extractor fans generally need to extract between 10 and 20 times the volume of the area of the room it is applied every hour, depending on use, i.e a 12m3 bathroom / shower area would require an airflow of 120m3/hr to 240m3/hr. Use a centrifugal bathroom fan if your duct run is longer than a 1.5 mtr and up to 12 mtr, although they are physically larger this type of fan motor offer greater pressure. Bathroom Extractor Fans, quiet fans for wall, ceiling and window mounting, high airflow low dB shower fan options, intermittent or constant extraction available on 230V or SELV Low voltage.īathroom fans of axial type are suitable for mounting through the wall and in the ceiling if using a very short duct run.
