Flue gas fan

A smoke fan is a fan whose task is to operate under extreme heat conditions, usually in the event of a fire. Smoke fans are a very important part of many of today’s safety systems in tunnels and buildings. There are a variety of standards that smoke fans are classified within, it can e.g. be F200 Classification for operation at 200° C for 2 hours F300 Classification for operation at 300° C for 2 hours F400 Classification for operation at 400° C for 2 hours Our many years of experience and large product range give our customers peace of mind. Development, design and manufacture of fans for smoke gas is done with the highest precision and with the highest quality materials. A smoke fan can be designed as an axial fan or impulse fan. To choose the right smoke fan, you should start from operating data and system design, as well as whether there are any special requirements.

Sometimes spare parts are not enough and the entire fan (with or without motor) needs to be replaced. We can help you with all your existing fans. To make the exchange as accurate as possible, we want as much information as possible about e.g. operational data and media. A good start is usually to use the rating plate on your existing fan.

Safe transport of explosive, highly corrosive, toxic or harmful substances is important in many processes and it is often extremely important to prevent these substances from escaping into the environment. Here, FläktComp Sweden can contribute with high-quality fans that ensure that the gas is handled correctly and safely over time. We have extensive experience in supplying gas-tight fans in various designs for a variety of applications. Sealed fans have fan housings that can withstand large pressure differences and are equipped with high-quality shaft seals that prevent gas leakage. Often more demands are placed on the fan than just gas tightness. It is not uncommon for aggressive gases to be transported, which is why we also have extensive experience in offering special materials or advanced surface treatment methods for fan housings and impellers.

Axial fans are a type of fan that creates airflow through a fan wheel that rotates around an axis and moves the air parallel to the axis. Axial fans can also be called propeller fans and are usually delivered as a complete unit consisting of fan wheel, motor and cover. Typically axial fans are direct driven with the impeller mounted on the motor shaft. There are also other designs such as e.g. belt-driven or with shaft bearing and coupling. The axial fan’s strength is to transport large volume flows at low pressures. At higher pressures, a centrifugal fan may be a better choice. To reach higher pressures with axial fans, these can be connected in series. Usually, the efficiency of an axial fan is comparatively lower than that of a centrifugal fan. But by using guide rails, diffusers and other accessories, an axial fan can reach the same or higher efficiency. The flow of axial fans can be regulated with vane or damper or speed regulation.
