Xpelair C4HTS 4-inch Simply Silent Contour Extractor Fan Humidistat

Product Information

The Blauberg 100 Quiet Style TH is the perfect solution for those looking for a powerful and stylish fan that won’t break the bank. German-engineered for quality and reliability, this fan boasts a powerful airflow extraction rate of 27 litres per second, making it perfect for use in toilets and bathrooms. Electricity and wet environments don’t match and it’s vital that the extractor fan you choose is safe to use. All manufacturers of bathroom extractor fans will state an industry standard known as an “IP Rating”.

Most domestic bathroom extractors attach to a 100mm hole in the outside wall. If you’re replacing a standard-sized extractor fan, this hole will already be present and you should be able to install the new one yourself. Before you remove the old fan, it’s a good idea to take a photo of its wiring for later reference – and make absolutely sure you shut off the mains power before you take the old one’s front housing off. The extraction rate of most bathroom extractor fans ranges from 18 to 26 litres per second. In short, the higher the volume an extractor fan can extract will result in improved performance with regards to reducing moisture and odours. However, too much extraction can lead to a negative air pressure, which can result in coldness in the room.

An over-run timer is a function used by many manufacturers and it works by keeping the fan running for a specified period. This functionality can be wired into an electric shower or more commonly into the lights. Most extractor fans for domestic bathrooms attach to 100mm openings. Therefore, if you are replacing an old unit, the installation shouldn’t take too long as there is no need to create a hole in the outside wall. In terms of noise output, they’ve improved massively over the years and all of our recommendations output less than 30 dB, which is considered almost silent. When looking at the different bathroom extractor fans, all manufacturers provide the dB measurements from a distance of 3 metres. This is an industry standard and it allows you to judge which are the quietest fans. However, it’s worth noting that some fans may be quieter because they are less powerful/extract less air. IPX4 rated, the Simply Silent C4HTSR range is suitable for use in bathrooms, toilets and cloakrooms in Zone 1 if protected by 30mA RCD, otherwise Zone 2 and can be window, wall, ceiling or panel mounted.

If you don’t already have a fan, you’ll need to get in a qualified builder to make the hole and install the wiring. Be aware that there are regulations governing where your fan can be located: if you want to put a fan in Zone 1 (the area within a shower or 2.25m above a bath) or Zone 2 (60cm from Zone 1), it must be a low-voltage SELV fan with a transformer, or an AC-powered model that’s IPX5-certified. Most of our recommendations below are intended for use outside of Zone 2, but the layout of your bathroom may dictate your options. Failing to remove moisture in your bathroom after you’ve had a shower or bath can potentially lead to long-term damage. If there is a window present in the room, you can open it to allow moisture to escape but if not, using an extractor fan is the best alternative. As well as dealing with excess humidity, they are also a great way of removing bad odours in the room too.In a survey carried out by ventilation specialist Vent-Axia, 40% of respondents said that they or their children had been woken in the night by a noisy bathroom fan. Even the cheapest fans are usually very quiet out of the box, but as the motor bearings start to wear – typically after about two years with low-end models – the blades can start to oscillate against the main housing, producing an annoying rattle in the process. A higher-quality fan should last longer, but if you value quietness then at some point you’ll probably need to repair or replace your fan. How do you install a bathroom extractor fan? The quality of the bathroom extractor fan also plays a big part because once the fan begins to age, it can become noisy. This is because motor bearings can begin to wear and blades may start oscillating against the housing. Therefore, choosing the best possible fan you can get your hands on will ensure that the quality remains for many years. The Size The PureAir Sense comes with two spigots (or sleeves): one for standard 100mm installation and another for larger 125mm portals. The larger spigot is the one to fit if you want to benefit from its excellent 39l per second flow rate. That said, its standard 32l per second flow rate is still better than most and easily good enough for the majority of bathroom installations. The C4HTSR model benefits from an adjustable over-run timer and a humidistat to automatically regulate humidity levels. The timer can be set at the point of installation between 30 seconds and 30 minutes. The C4HTSR range of 4 Inch extractor fans benefit from a range of features which allow them to deliver near silent running. Advanced Ghost™ Air Movement combines long-life silent running motors with precision engineered components alongside advanced air flow management which eliminates irregular air flow paths which can cause noisy extraction.

These fans have both an overrun timer and a humidistat. There is an automatic mode and manual modes. This means the fan will either come on when the ambient humidity in the rooms goes above the set point. Or the over run timer will function the same as above to help clear excess humidity after the switch has been turned off

Comprehensive Research: Our team dedicates extensive time and effort to research and analyze products, so you can make informed decisions. The precise duration of the overrun is normally configured during installation, with most fans offering a range between 30 seconds and 30 minutes. You might as well tend towards the latter end of the scale as the cost is very low: on average, a fan like this uses around 8W. Building regulations state that in the UK, a bathroom or shower room should have a fan capable of extracting at least 15 litres per second.

Features of Xpelair Simply Silent Contour C4HTSR Include: Humidity extractor fans can be very effective in reducing excess moisture in a room or area. They work by drawing in humid air and expelling it outside, which can help prevent mould growth, reduce the risk of respiratory problems, and improve overall air quality. However, the effectiveness of a humidity extractor fan depends on several factors, such as the size of the fan, the size of the room, and how often the fan is used. It is also important to properly maintain the fan, including regularly cleaning the filters and ensuring that it is installed correctly. Overall, humidity extractor fans can be a useful tool in managing humidity levels, but it is important to do your research and choose a high-quality fan that is appropriate for your specific needs. Independent: We will tell you exactly what we think of a product and we would never recommend anything we wouldn't use ourselves. The rate at which air can be extracted from the bathroom is one way of determining the performance of an extractor fan. The measurement used for the extraction rate is litres per second (L/s) or metres cubed per hour (m3/hr).
