Ventilation Fans: what type of extractor fans you need, where, and why

Ventilation plays a huge part in all of our lives, keeping the air in our homes safe to breathe and free from contaminants. There is no question of whether you should have a quality ventilation system installed, but the big question is which one and what ventilation fans should be installed where? Airflow has sought to answer this question with a variety of fans that all comply with Building Regulation laws. These regulations state that a minimum flow rate is needed from an extractor fan when installed in a ‘wet room’ of any kind. The term ‘wet room’ covers toilets, bathrooms, utility rooms and kitchens as these rooms all use water frequently. There is no ‘one size fits all’ ventilation fan solution, so it is important that you purchase the right fan for the job in question. In this article, we would like to inform you of which ventilation fan should be placed in which wet room of your home, to prevent damp and other contaminants. The importance of minimum airflow rates in wet rooms Airflow rates are recorded in litres per second (l/sec). Here are the following minimum airflow rates for each kind of wet room: Toilets = 6 l/sec Bathrooms = 15 l/sec Utility rooms = 30 l/sec Kitchens = 60 l/sec (30 l/sec in kitchens where the fan is placed adjacent to the hob. This is also the minimum flow rate expected from a ducted cooker hood). Why is it so important that airflow rates meet these minimum levels in each of these rooms? The primary reason is that insufficient airflow results in condensation, damp and eventually mould if it goes untreated. However, if you ensure the fan that you have installed performs at the correct airflow rate, then the excess moisture will be eliminated. This means there will be no risk of the growth of mould in your wet rooms. What are the different ventilation fan types and their features? Axial fans Axial fans are a type of fan that causes the air to flow in an ‘axis’ motion, which runs parallel to the shaft where the blades rotate. This creates a pressure difference which causes airflow through the fan. They provide high performance and volume levels, considering their small profile - and they are very unobtrusive. We at Sparks sell some excellent axial fans with very slim proportions. For instance, Envirovent’s Silent Extractor Fan is only 146.5mm in diameter and provides an impressive 78l/s. This makes it highly suitable for kitchens where it will operate with minimal fuss: silent and discreet. Axial fans must overcome a limited amount of ‘backpressure’ (which is caused by internal components). This means it should not be used on longer duct runs - 1.5 metres and over - and on ducts with a minimum of two 90 degree bends.Buy Silent Extractor Fan 150mm Centrifugal Fans Centrifugal fans extract air at a right angle to the fan’s intake and spins the air outwards by using centrifugal force. The impeller rotates, causing air to enter the fan near the shaft and move in a straight line to the opening in the fan casing. This allows the fan to produce more pressure for a certain air volume and is therefore able to push the extracted air along far longer duct runs. Centrifugal fans are often more expensive than their axial counterparts and are sometimes larger to accommodate their greater power. However, this is not the case with some newer, sleek models that look very alike to axial fans. Mixed Flow fans Mixed Flow fans combine some of the high-volume flow aspects of the axial fan with the pressure delivery of the backward-curved centrifugal fan. These fans come highly recommended by the trusted site Professional Electrician, as they are able to combine convenient size and strong performance. For example, the Airflow Aventa is slim, 6 inches long, and provides two fans in parallel for double the flow - producing an exceptional 552m3/hr. They are very popular in kitchens and bathrooms, as they produce high airflow rates needed for kitchens. Furthermore, they are ideal for short to medium duct runs - in toilets and smaller utility rooms for instance.Buy Airflow Aventa Mixed Flow Fans Which ventilation fan type should go where? As stated before, there is no uniform solution of where to place your ventilation fan. You must consider a variety of factors, such as the length of a duct and the number of bends in it. These things will create a resistance to the fan’s airflow that it must overcome to reach its ‘operational performance’. With axial fans, the use of an axial impeller is ideal for bathrooms, toilets and smaller rooms, where the fan is to be ducted straight through the wall or installed in a window. Axial fans are suited for fitting through the wall or ceiling, as well as along short runs of ducting applications. The powerful centrifugal fans are often found in kitchens or very large utility rooms. They are frequently placed in rooms that do not have exterior walls. This is because such rooms do not have natural ventilation, and this means they require a long duct run to reach the outside of the building. Meanwhile, mixed flow fans are seen to bring the best of both centrifugal and axial fans together, with both power and discreteness. They are a perfect choice to bridge the performance gap between axial and centrifugal fans.

Health Problems caused by Condensation and Top Tips to Avoid its Build-up

When moisture makes contact with a cooler surface, such as a window or wall, the warm air around it is unable to hold the same amount of moisture. This means the water is released onto the colder surface, creating droplets of water - referred to as ‘condensation’. Condensation may also form in areas where airflow is limited, such as behind bedroom furniture or inside wardrobes. Any area that is not open to light and the occasional bit of airing is susceptible to condensation. The main problem associated with condensation is mould, which may start to form on clothes, furniture and walls if the problem is left unchecked. Ventilation specialists such as Envirovent have been working for decades to provide products that prevent these conditions. Condensation - spotting the problem early on With the rise of so-called ‘energy conscious’ housing, many of us have implemented energy-efficient ways to stop heat escaping our homes. These measures include insulation, draft-proofing, double-glazing and the blocking of chimneys - all of which increase the humidity of our indoor air, which leads to condensation. If your home is suffering from condensation you will start to see signs very quickly. Look out for the following: Steaming windows. Wet walls. Damp areas on walls. Wallpaper may be peeling. There may be signs of mould growth (most commonly in unaired spaces). There may be a musty smell on your clothes. Black dots appearing on your window frames. Soft furnishings and fabrics become more prone to mould and mildew. Don’t become complacent when it comes to condensation. Steaming windows are the most obvious sign that you have an underlying problem that needs to be resolved. If you do not react fast enough, you will leave yourself vulnerable to a recurring issue that may have debilitating effects on the residents of your household. Wet windows are the first sign, and will inevitably lead to problems such as damp patches on walls, peeling wallpaper and - worst of all black mould growth. However, it is one of the most common problems that home-owners will have to face, and one which can be tackled if you follow our advice. If you wish to carry out a completely free home survey, provided by Envirovent (a company which was established to provide healthy ventilation through eco-efficient means), then click here to arrange one at your convenience. Damage and health problems posed by condensation Condensation remains arguably the largest cause of dampness in indoor areas, and can eventually lead to the growth of mould. If left unaddressed, condensation can damage property by fraying curtains, peeling wallpaper and creating a generally musty environment. The health problems associated with mould have to be emphasised also, for mould can lead to a litany of ailments. Prolonged exposure to copious levels of indoor dampness can reduce lung function and cause chronic health problems such as asthma. When exposed to mould, those who already suffer from asthma and allergies are more likely to have more severe symptoms.It can lead to other serious medical conditions, such as bronchitis and pneumonia. According to the World Health Organization (WHO), a considerable proportion of the world’s 300 million cases of childhood asthma are attributable to exposure to indoor dampness and mould. It is a problem for the entire family, or any group of residents that live in a mould-infested building.Buy Silent Fans at Sparks Our tips for avoiding the build-up of condensation With careful planning, you will be able to prevent condensation from forming in your home - before it becomes a problem. Condensation prevention techniques help ensure that your property remains both damp and mould-free. This will save you having to spend more money in the future by continuously removing condensation. Here are our tips: Try to keep your interior temperature reasonably constant. Avoid drying clothes indoors. Do not dry your clothes over any type of radiator. Ensure tumble driers are properly vented or that the condensation build-up is regularly emptied. Keep your furniture a good distance away from your walls. Do not switch off or disable extractor fans for an extended period of time. Ensure your extractor fans are well maintained and offer sufficient airflow. Many of us fall victim to spotting condensation and not thinking it is not a serious problem. We may only open a window to air out the room in response, but sometimes this is simply not enough. Opening a window may exacerbate the problem, as the weather outdoors has more moisture and higher humidity than the inside of your home. If humidity levels reach 50% or above, then this could trigger the worsening of existing allergies and asthma conditions. A great tip for preventing condensation and dangerous humidity levels is to get yourself a dehumidifier. They prevent condensation by providing a continuous source of fresh air into your home. A prime level of ventilation is essential for locations such as the kitchen, or wherever you wash and dry your clothes. Good ventilation is also required in your bathroom to eliminate moisture that is produced by taking a shower or bath. However, there are a few downsides to dehumidifiers. They must be emptied on a regular basis and are only effective in the room where they are placed. They can consume anywhere between 50 to 800 watts in a single day. However, these slight setbacks are worth it, if it means staving off the ultimate enemy - harmful and mouldy living conditions.
