However, Hunor wouldn’t have been a true inventor, if he had been satisfied with this. ![]() Thanks to its special design, it drove the molecules to the right place, aka straight to the extractor fan’s surface. A motor that is twice or three times more powerful – and obviously much louder – wouldn’t solve the problem on its own.Ĭurty, as a sticky foil, was easy to apply on the extractor fan. If an exhaust machine wants to guarantee a 100 percent smell-free result, the surface of the kitchen extractor fan should extend 1 meter in every direction (left, right, forward and backward) beyond the cooker itself. This problem has already been eliminated by ALLin Kitchen Ventilation concept’s first “manifestation”, the so-called Curty, a specially stiffened foil that was applicated on the exhaust fan. For those who cook and bake hours on a regular basis, this could add up to be almost 3000 EUR of a pointless waste of money in 10 years. In wintertime warm air escapes while during summer – if the flat is climatized – rooms get warm at a moment’s notice. This smell can only be removed with long aerations, that, however, raises the problem of wasting. Have you noticed that the minute you start to bake or cook, the smells permeate your home? The explanation is simple: steam and hot particles released from the pan follow an irregular motion that forces them to spread out not only upwards but, as an inverted cone, in every other direction as well. Other kitchen exhaust fans with different construction – unlike their promising name – are not capable of extracting the bad smells that go hand in hand with cooking and baking either. That is the seemingly unsolvable problem that concerns most of the households where people cook and bake a lot. Not to mention the damage that the combustion products and charred particles could cause to your respiratory system. (At least according to the currently available kitchen extractor fan options on the market.)ġ litre of fat per year….it is horrible just to think about the thick layers of grease that settle on your furnitures. That means that almost one-quarter of the – let’s face it, not so appealing – airborne grease gets onto your furniture. An average household produces 4 litres of airborne grease in a year, so it is easy to do the maths and realize that the remaining 25 percent of airborne grease – almost 1 litre – ends up in the space around the extractor fan. That makes them unfit for being a good extractor since the human nose can detect and consider unpleasant even 1 percent of released smell. ![]() If the resulting reading is anything but zero, then the switch is faulty and must be replaced.One of the problems is that the so-called premium kitchen exhaust fans only absorb water vapour and 75 percent of oil and fat molecules. If they appear to be intact and fault-free, use an ohm meter on the wires that relate to the power switch. Visually check the wires for any sign that something may be amiss. ![]() Turn off the power supply and remove the cover by unscrewing the fasteners that hold it in place. In this situation, the wires must be replaced. The wires can also become loose or frayed. The location of a kitchen exhaust fan can sometimes cause the wiring to melt. Check whether you can see a build up of moisture. Remove the cover after switching off the power and clean the inner surface of the cover. ![]() MoistureĪ build-up of condensation in the kitchen exhaust fan can result in moisture dripping from it and causing staining to the surface beneath. Alternatively, check whether the fuse has blown and replace it if this is the case. Check whether the appliance has tripped the circuit breaker and switch it back into place if this has occurred. If the exhaust fan fails to work at all when you switch it on, there are a few possible causes. Repair or replace any components that you find to be faulty and make sure the screws are properly tightened when you replace them. If they are correctly secured, unscrew them in order to remove the cover and check for any loose parts. After switching off the power supply, check the fasteners holding the cover in place. RattleĪ kitchen exhaust fan that rattles when it is in operation is likely to have loose or defective components that will have to be rectified. Then check the manual to determine whether it outlines any recommendations as to suppliers. Ensure that the new part is made by the same manufacturer as the fan and is the correct model. Carefully unhook them before removing the other fasteners that hold the motor to the support and reverse the steps with the new motor. Switch off the power supply and remove the cover of the fan to access its wires. If you have retained the instruction manual, keep this on hand during the removal process to help you to identify relevant components.
