Residents of large cities have probably already noticed that the usual shuffling of a broom in the morning has been replaced by the buzz of motors. It was the janitors who were given new equipment for cleaning the streets – knapsack blowers. Gasoline engines make these devices autonomous, the blower is conveniently placed behind the shoulders, it can be carried and transported to any distance. A knapsack blower will also come in handy in the private sector – there is a lot of work for it here.
What is the principle of operation of gasoline knapsack blowers, how to choose the right model of this device – this will be an article.
How blowers work
The principle of operation of blowers is approximately the same as that of a vacuum cleaner. The difference lies in the fact that air is not sucked into the device, but, on the contrary, is blown out of it with a certain effort.
This allows you to blow fallen leaves, grass clippings and other debris from the most inaccessible places, as well as collect it in a heap. The owner of a powerful device must understand that he is unlikely to be able to collect all the leaves from the site in one place – the blower is not designed for this.
Blowers are also used for other purposes, such as cleaning garden paths, gazebos, yards, and blowing debris from hard-to-reach places. In fact, this device does the work of a broom, garden rake and vacuum cleaner at the same time. With it, you can even collect needles from coniferous plants, wet and caked foliage, blow garbage out of dense thickets and hard-to-reach areas (such as gutters, for example), clean outbuildings and garages.
Generally, Blowers have a lot of pluses, and the performance of these devices largely depends on the type of motor and its power.
Varieties of blowers
Blowers are distinguished by size and type of motor. So, depending on what drives the engine of the device, there are:
- Electrical Modelsoperating from the network. Such devices are tied to an outlet, so their range is limited by the length of the cord. Otherwise, electric blowers are very convenient because they are light, powerful and quiet.
- Battery Models useful to summer residents, because they are very mobile and compact. Basically, these are hand-held devices that need to be kept on weight during operation. The mass of devices is small, but it increases in proportion to the capacity of the battery. Almost all battery models are low-power, their battery charge is enough for 10-20 minutes of operation.
- Petrol engine – The most powerful. Such blowers are rarely manual, because it is quite difficult to keep a working two-stroke engine with other devices on the weight. More common is a gasoline knapsack model, which, by means of belts, is conveniently located behind a person’s back.
In large private households, it is the backpack-type gasoline blower that is most often found, because this device is the most powerful and productive.
