The smells of fried onions from the neighbors, puddles under the windows and on the walls, fungus and mold in the bathroom, aromas from the restroom hovering around the apartment ... It looks like you have problems with ventilation. We've broken down the top 4 inch inline duct fan so you can choose the best one for your space's needs.
The modern market is filled with models of duct fans for every taste and budget. The principle of work is divided into:
Mechanical - the most simple
4 inch inline duct fan comes with an external (connection to a light switch) or built-in switch. This type of fan is the most economical. But not practical! Turning on with the light, the fan may not have time to draw out moisture and air while you are in the bathroom or restroom.
Fans equipped with a timer, as well as mechanical ones, are connected to the switch. But they continue to work for the programmed time (from 2 to 30 minutes) after turning off the light.
The humidity sensor is usually an optional feature for fans with a delayed shutdown timer. When the humidity level is above normal, the fan automatically turns on until it does its job.
The motion sensor activates the fan only when there is someone in the room, significantly saving energy costs.
Before choosing a duct fan, you need to check the “viability” of your ventilation ducts in your multi-storey building. Make it easy. Open a window for ventilation, and attach a sheet of thin paper (toilet paper, paper handkerchief) to the duct opening.
If it holds, then the ventilation duct is working and you can start choosing a 4 inch inline duct fan. If not, then you need to contact the utility services to solve the problem, since the problem of lack of air ventilation cannot be solved even by buying the strongest fan.
The first step in choosing 4 inch inline duct fan is measuring the diameter of the ventilation duct. The most popular models come with a connection diameter of 100 mm and 150 mm. But in the modern market you can find models of any non-standard connection sizes - from 110 to 400 mm.
It is necessary to proceed, first of all, from the area of \u200b\u200bthe room. For bathrooms up to 9 sq.m., the capacity should not be less than 90 m3/h. If the bathroom is combined with a restroom - add another 30-40 m3 / hour, total - at least 120 m3 / hour. If the bathroom area is more than 9 sq.m - look at the fans with a capacity of 150 m3 / h and more.
Be aware that fans make noise. And if it is too strong, it will certainly interfere with the residents, especially at night. Therefore, pay attention to the noise level that the fan you choose produces.
Up to 25 dB - you will hardly notice its operation, from 25 to 32 dB - barely audible noise, from 32 to 40 dB - audible during switching on and during operation, over 40 dB - a rather noisy fan, but is allowed for use in residential premises from 7:00 am to 11:00 pm.
And of course, not the last place is occupied by the style of the interior and the fan in it. To make the device inconspicuous, to put an accent or to complement the interior is not a difficult task now.
4 inch inline duct fan manufacturers bring to the market all new models in a different color palette, with decor and lighting. Decide what color you need and choose the best of the models presented in the top.
As mentioned above, the modern choice of fans pleases. Though red, even green, square or round, quiet or very quiet, with a humidity sensor or with a timer ... But, most importantly, as with the purchase of any household appliances, it is necessary that the device be of high quality.
