We recommend planting the posts at a distance that depends on the characteristics of the ground; if the ground is flat, put one every 5/10 meters, if it is a windy or uneven area, put them closer together.

The 6mm² thick electric wire for fences is suitable for wild boars and large animals. The wire for fencing has a tensile strength up to 100kg, 8 conductor wires and a dispersion of 0.15 ohm/m. The sling for electric fences is suitable for electric fences for horses.

To create an electric fence for animals you need: a Gemi energiser - 100% Made in Italy - for fences that carries the current to the fence, an electrified conductor wire for the fence and insulators for electrified fences screwed on the posts to hold the wire.

The electric fence for animals is neither dangerous for people nor for animals. As with everything, even for electric fences there is a standard that establishes the values ​​to be respected. The fence energiser is a product that emits intermittent pulses with a low amperage.

The Gemi electric fence - 100% Made in Italy - is used to ward off wild animals such as wild boars, deer, foxes, etc. The purpose of electric fences is to protect the territory from unsightly invasions. It is also used to contain animals such as cows, sheep, pigs etc. It has nothing to do with hunting. We have all the legal certificates available to produce and sell electric fences. This is the only legal solution for those who want to protect their plantations.

There is no problem, the smoke extractor works normally. The chimney fan is designed to ensure normal running-in of the internal bearings. The fan should initially be run in at higher speeds and after a few minutes it can be switched to lower speeds. This mode of operation should only be followed for the first month, after which it will also run at lower speeds.

The regulator of the chimney fan for fireplaces must be connected to the 220 V current and can be installed in any area, the important thing is that it is not placed near heat sources. In fact, inside the regulator of the chimney fan there is a transformer that works at high temperatures.

The weight of the fan, excluding the speed regulator, is about 20 kg.

No. The chimney fan is silent at any speed. Of course, if you set it to the sixth speed, the fan makes more than 1300 revolutions per minute, so you will hear a slight humming sound. But to solve the problem of smoke, the fan should be used at low speeds, from the first speed up to the third speed. At these speeds the sound pressure does not exceed 38 Db, i.e. zero noise.

Yes, we supply adapters for round flues (those indicated in the product drop-down menu). To order the adapter, simply select the round flue and choose the size of the adapter you wish to purchase from the drop-down menu. You have to take into consideration the external diameter because our adapter for flues fits externally to its outlet. If the chimney has an external diameter of 25 cm, the ideal chimney adapter will be 25 cm in the drop-down menu.

Yes, thanks to the suction power of the chimney fan there is no problem even on chimneys longer than 50 meters.

Certainly, our chimney fan is suitable in case of strong wind because it solves the problem of smoke.

No, the base of the chimney smoke extractor has been raised to prevent water infiltration in the event of rain.

No, the chimney fan does not plug the smoke outlet if it is switched off. For this reason it is possible to switch on the chimney fan only in certain situations, for example when raising the stove door or in case of strong wind.

The professional fan for fireplaces can be installed at any height, even on flues of 1 meter. On the other hand, the basic model of the chimney fan is recommended for chimneys over 3 m high.

There is no time limit. The chimney smoke extractor can work all day without any problem.

Yes, it is possible. There are two ways to make the electrical connection: with the 3 x 1.5 cable (to be run outside the chimney up to the speed regulator) in order to extend the first metre attached to the chimney fan. Or you can make an internal connection to the chimney with our high-temperature resistant cable, which you can purchase separately by selecting the desired quantity in the drop-down menu according to how many meters you need.

It is possible, but you have to consider the dimensions of the chimney fan. The installation of the smoke exhauster can be done in two ways: eliminating the cap of the chimney and then installing the chimney fan, or inserting inside the chimney the chimney smoke extractor, ordering in this case the smoke extractor without the cap.

If you have a square chimney with a pipe of the same height as the masonry, you must first close the gap between the pipe and the masonry and then install the chimney fan directly on the masonry. Similarly, if the pipe is only a few centimeters (or inches) high, the pipe must be brought to the same height as the masonry. In this situation you have to buy the model of chimney fan with square base, adjustable also for rectangular chimney.

The assembly of the chimney smoke extractor is do-it-yourself. Watch the tutorial video on the product sheets to assembly the chimney fan. If you encounter problems with the installation of the extractor fan, you can ask for the help of an electrician or a bricklayer. If you have any doubts about the installation of the product (e.g. connection of wires, speed regulator, etc.) our specialist technicians will be at your disposal via email, chat or telephone.

The function of the smoke extractor is to regulate the draught of the chimney, in order to solve the problem of smoke in the chimney, oven, stove, barbecue and to reproduce the natural draught of the chimney.

The base of the electric chimney fan is standard 43x43 cm, the height is 35 cm, without the brackets. Considering the brackets it is 50 cm. For more specific measurements, a diagram showing the measurements of each individual part of the electric fireplace extractor fan is available on our website.

Our electric smoke extractor has a 6-speed regulator, so you only need to set it to speeds of 1-2 to help extract smoke naturally, but not heat. Basically, at the first two speeds, we are not altering in any way the normal operation of a fireplace, which would normally disperse a very small amount of heat in the smoke rising in the flue pipe. The Gemi chimney fan sucks up the smoke that would otherwise go into the house and therefore, certainly, would not produce any heat sources for the indoor environment. It is clear that if the chimney fan does not operate at the sixth speed (usually at this speed it is used to change the air in rooms, to help start fires or to suck up the ashes), with its 2500m³/h(basic) - 3800m³/h(pro) it will be so powerful that it will also suck up the heat, because it will increase the speed of combustion of the wood and consequently partially reduce the heat. Scientific studies have shown that the Gemi smoke extractor can control heat loss, so it is advisable to use a chimney to prevent heat loss. This can be seen in the millions of satisfied customers all over the world since 1983, when the first Gemi chimney fan was created.

The basic model has a suction capacity of 2500 m³/h, a 3-year warranty and can withstand up to 300 degrees. The professional model can withstand up to 700 degrees (therefore also in case of a chimney fire) and is recommended if you have a chimney of less than 3 meters. It also has a 6-year warranty and sucks in 3800 m³/h. The steel model is built entirely in Aisi 304 stainless steel, a material that ensures greater resistance to corrosion and saltiness and therefore over time. It has a suction power of 3800m³/h and a resistance of up to 700°, guaranteed for 8 years. The top of the range offered by Gemi is the professional copper model, resistant up to 700°, with a 10-year warranty and capable of sucking up 3800 m³/h. The stainless steel fan resists corrosion and saltiness. It is fully painted on the outside (including the base) and is therefore suitable for those looking for a more aesthetically pleasing product.
