New Silent Sub Floor Ventilation Kits

Many customers are after a sub floor ventilation solution that is quiet. The main reasons for this are the fan motor may be installed within relatively close proximity to a living space, such as a living room or bedroom. For them it is important to not be able to hear the motor in any way, both in terms of a motor humming or airflow flowing through it.

A quiet solution to ventilating your underfloor area

We are pleased to introduce our new range of silent underfloor ventilation kits. Our quiet sub floor kits include the popular TT Silent Mixflow inline fan. This fan has been specifically engineered to operate very quietly and has the decibel figures to back this up. For example the 150mm model is rated at only 33 dB(A) when wired to the high speed, which is very quiet indeed. Our silent kits are designed to service large underfloor areas, despite being quiet they are also still powerful motors capable of helping eliminate any issues you may have in your sub floor area such as dampness or mould growth.

We have recently launched the new range of Ventair Airbus fans, including a model with an all new low profile square cover and a model with an integrated LED light. The Airbus is a popular ceiling mounted exhaust fan as it comes with a powerful motor capable of long distance duct runs. There are not many ceiling mounted fans on the market that have this capability.

These new fans are part of our ceiling mounted exhaust fans category.

Run on timers for exhaust fans are designed to keep the fan operating beyond the point of you switching the fan off. This ensures that the room is ventilated adequately.

When would I need one?

Run on timers are popular for rental properties, as generally tenants may not be as vigilant as homeowners when it comes to leaving the fan on until all steam has been removed from the bathroom. If the fan is not left operating for long enough then over time this can create issues covered in this blog post.

They can also be popular if you have the fan wired to a light switch – invariably when you leave the bathroom you will turn the light switch off – therefore the run on timer ensures that the fan stays operating beyond this period.

What Run on Timer options do you have?

We sell two types of run on timers:

The first is an adjustable 2-30 minute run on timer. This gives you the ability to pick exactly how long you want the fan to run for (as long as its between 2-30 mins). This would need to be wired by an electrician and is compatible with most fans that we sell, including inline options.

The second option is a fixed 7 minute run on timer. This is a fixed 7 minute timer and is only compatible with fans that have an axial motor. If you are unsure of compatibility its always best to ask us, however with products that are compatible with this fan we will have the timer listed as an accessory.

Please note: All run on timers will need to be hardwired to the fan/motor by a qualified electrician.

We are excited to announce the launch of a new ceiling mounted exhaust fan! The Fanco VP Exhaust fan is a high quality ceiling mounted fan with a powerful centrifugal motor. The centrifugal motor has many benefits – the main one is that the fan can be ducted long lengths without adversely effecting the performance of the motor too much. Many ceiling mounted fans are generally only designed to be ducted a couple of meters – however this model provides the exception! With a powerful capacity of 310 m3/hr the fan will work well in both domestic and commercial situations.

Another benefit of the fan is that it can be installed in relatively confined spaces. The motor is only 165mm high which naturally makes it a good choice if you have limited roof cavity space. The fan can be connected to 125mm ducting and has a very modern minimalistic cover.

The IXL Eco Ventflo is a new high capacity ceiling mounted exhaust fan from IXL. The fan has a sleek round silver cover with a powerful extraction rate. The fan also includes a backdraft shutter which makes it suitable for 5 star energy homes where exhausting into the roof cavity is permitted.

The fan is available in 2 sizes a 200 and 250 model:

  • 200 model
  • 250 model


  • Self sealing back draft shutters eliminate unwanted cold/hot air from entering the room when the fan is not in use
  • The exhaust fan is IP24 rated so that it can be positioned directly above a shower
  • Stylish and unobtrusive design means it suits any bathroom or wherever an exhaust fan is needed
  • 3 year replacement warranty for peace of mind

Many older style ceiling exhaust fans are non ductable, meaning they simply exhaust into the roofspace. Here we will briefly take a look at the difference between a ductable fan and non ductable exhaust fan and the benefits of each model.

Non Ductable Fans

As mentioned non ductable fans simply exhaust into the roofspace. For this to be a viable solution you would need to have a well ventilated roofspace in the first place to avoid problems down the track. This is an easier system to install as you do not have to connect ducting and an external vent.

Ductable Fans

Most modern fans on the market are now what you would call ‘ductable’. This means they have an outlet on the motor allowing for connection to flexible ducting. Depending on the model this duct size will generally be either 100mm, 125mm or 150mm for a domestic exhaust fan. Our most popular choice as a ductable fan is the Luna andMetro range, as they come with a back draft shutter and operate quietly. The obvious benefit of a ducted system is the exhausted air is going straight to the outside and not into the roofspace.

I want to replace my old non ductable fan for a ducted system…

This can be easily done – firstly you would need to measure the hole size of your old fan, so remove it completely and measure the diameter of the hole. You can then visit our range of ceiling exhaust fans and pick a fan with the same hole size. You would then need to run ducting from the fan to your external vent. At Pure Ventilation we stock a huge range of accessories to go with your fan, you can view all of this here.

The Edmonds AiroMatic is the first of Edmonds range of ventilators developed using advanced CFD (Computational Fluid Dynamics) software, as used in the aerospace industry. This software has allowed Edmonds to produce a ventilator with a higher flow rate and efficiency than other ventilators while reducing its overall noise level and physical size.

The unique Edmonds design speed controller allows the selection of three fixed speeds, allowing just the right amount of flow to be set to suit the severity of the conditions without increasing power consumption.


  • Removal of heat trapped in the roof cavity of a home in summer.
  • Removal of moisture trapped in the roof cavity of a home in winter.

Temperature Control – Cooling mode

Set to automatic the unit senses temperature and switches on at low speed when the roof space temperature reaches 30°C. As the temperature rises, the inverter technology used in the Edmonds AiroMatic, proportionally increases speed until the maximum speed is reached at 45°C.
This means that the fan is only drawing as much power as needed to keep the roof space cool.
One of the benefits of reducing roof space temperature is improving air conditioning efficiency and reducing the cost of running them.

Condensation Control – Drying mode
Condensation can potentially cause mould, mildew and building damage. Using any of the three speed manual control settings, the AiroMatic can effectively draw fresh and dry air into the roof cavity, removing moisture and helping to protect your home and the health of your family.

A window exhaust fan is generally a popular choice for bathroom installation and they are typically found in apartments and unit blocks. In this post we will look at suitable positioning, how the fan is installed and wiring options.

A window can be a good choice of location for an exhaust fan as they are generally located opposite the door. With any bathroom exhaust fan your aim is to create a good cross flow of ventilation, allowing for the greatest amount of air circulation possible. So ‘fresh’ air enters under the gap between the door and the floor and is exhausted out via the window fan across the room. See the below diagram for an ideal setup:

If your window is poorly positioned you may wish to consider other means of exhausting, such as a wall mounted fan or roof mounted fan.

We find that most people are looking to replace an existing fan that may be very old. The process of finding a suitable replacement is simple, all you have to do is completely remove the old fan and measure the hole in mm. With this measurement you can go through our range and find the most appropriate fan. If its a new installation all you would need to do is hire a glazier to cut the required hole. Most fans come with a cutting template to assist with this.

Wiring Options for a window fan

All window fans need to be hardwired by an electrician. At Pure Ventilation you have the option of purchasing the fan with a lead and plug, meaning our technicians will install the plug to the fan. This ensures simple plug in installation like any other household appliance, such as a kettle etc. The fan can also be wired to an optional on/off wall switch (electrician required) meaning it would have to manually be turned on/off by the user. A popular choice for rental apartments is wiring the fan to the light switch. This ensures the fan is always turned on with the light, which avoids careless tennants who may not use the fan otherwise!

Roof Exhaust fans are a great solution where there is limited installation space for a fan, or to move the fan motor outside the room to reduce the noise generated. They are suitable for a range of applications – from bathrooms and toilets to range-hood alternatives. Our roof exhaust fans have varying capacities and we have particular models for installation for both metal and tiled roofs to suit your particular needs.

There are two primary fan variants:


  • Axial fans – suitable for small-medium spaces (toilet, powder room, laundry)
  • Centrifugal fans – suitable for larger spaces and range-hood alternatives


Calculating Volume

Calculate the area of the room you wish to install the roof exhaust fan (Length x Width x Height). Then multiply this number by the number of air changes required (approximately 10 for a standalone toilet and 15 for a shower). This will give you the approximate capacity (or airflow) required to ventilate the room.
