The maximum flow of air or motor flow of air indicates the theoretical capability of the device. This parameter of the hood (motor) is measured during idle operation. By connecting the duct and working in the appropriate mode of extraction, the flow of air will be lower. However, high-performance motors will also give a high flow of air in extraction mode.
Lighting method provided as standard in the hood.
— Incandescent lamp. The simplest and most affordable of modern lighting sources. The main advantage of incandescent lamps is their low cost. In addition, they give a fairly eye-pleasing light in warm colours. On the other hand, such lamps are the most energy-intensive. Besides, they get very hot during operation.
— Halogen lamp. An improved version of the incandescent lamps described above. They are distinguished by higher brightness at lower power consumption while also having a spectrum of luminescence that is pleasing to the eye. At the same time, halogen lamps are still inferior in terms of efficiency to fluorescent and LED lamps.
— Fluorescent lamp. Also known as "fluorescent light bulbs" or "energy-saving light bulbs". One of the advantages of such lamps is just low power consumption — many times lower than that of incandescent lamps (although higher than that of LEDs). The light from fluorescent lamps is white, rather cold; this can be both an advantage and a disadvantage, depending on personal preferences and interior features. But of the unambiguous shortcomings, it is worth noting that most of these lamps contain mercury vapour in the flask; because of this, failed light bulbs must be disposed of according to special rules, and a broken lamp can become a source of health problems.
—
Light-emitting diodes (LED). The most advanced of mod
...ern lighting sources. LEDs are highly energy-efficient. They are more economical than incandescent lamps, and they practically do not heat up during operation. The light from such sources is neutral white, which is quite suitable for most cases. The disadvantage of LEDs is a rather high price.
Note that many modern hoods allow you to replace a regular light source — for example, a halogen lamp can be changed to a fluorescent or LED lamp with the same base.The duct diameter characterizes the size of the hood outlet to which the ducts are connected. The standard is either
120 mm or
150 mm. In many cases, an adapter from one diameter to another can additionally be included with the device. However, when replacing the hood with a new one, it is still better to operate with the existing pipe diameter and not use adapters.
