We choose the duct for extraction. What is important: beauty, life or security?
Good owners want to create in your homea unique atmosphere of comfort and beauty. A special interior, a choice of furniture and stylish accessories are thought through by them to trifles. But it is equally important that there is always fresh air in the room, and in the elegant living room there is no smell of borscht or cutlets. The ventilation system requires special attention also in the event that you do not want to see the mold on the wallpaper and the dampness in your favorite bathroom. Fans in bathrooms will get rid of unpleasant smells and excessive humidity, and in the kitchen it is better to resort to the help of special equipment.
Duct for ventilation is not the last placewhere there is a struggle for the purity of the air. The buyer faces a difficult task: to make the right choice in favor of a round, flat, steel, plastic or corrugated version. The task for all is one - the withdrawal of air into the ventilation shaft. By the way, a flexible air duct for hoods has gained special popularity with most consumers due to the simplicity of installation and a small price. Work on its laying will require a minimum of time, and accurate preliminary measurements are not necessary. In addition, they have high tightness and a service life of more than ten years. The pros are obvious. But it is worth to know that the duct for drawing, made of a thin aluminum sheet during the operation of the fan can make a rustling sound. Choosing is more dense, although it does not guarantee a complete absence of rustling.
A plastic duct for drawing can berectangular or round. Both options have a rather aesthetic appearance. The circular cross section is optimally suited for heat absorption and noise insulation. Flat form is very convenient when stacked in shtobu. It also allows you to place pipes that take air out of the kitchen, and above the top of the cabinets, and with a successful installation they can remain virtually unnoticed. The advantages include absolute safety for health, excellent hygienic properties and simple care. Minus - low fire resistance.
When choosing a duct for drawing, it is worth remembering thatfor the turns you need plastic fittings: corners, elbows (bends) and transitions. To correct the length of straight sections suitable for a regular saw for a hacksaw.
A good work of the system requires attention and a non-professional approach. When planning, it is worth considering the recommendations common to all.
First, the air duct for the hood should ideallyhave a small length, and all kinds of twists and turns it is generally desirable to avoid. Each of them affects the productivity of the hood, reducing it by 7-15%. Secondly, the tightness of all joints should be ideal. It is extremely important that the cross-sectional area remains constant throughout the air removal path. Otherwise, when the air duct is narrowed, it will be more difficult for the fan to "push" the air. And this is fraught with increased noise and energy costs, and the hood itself will be subject to faster wear and tear. And note: a slight slope of the horizontal section of the ducts, directed towards the outlet, will be a tangible plus in the work of the exhaust system as a whole.
