Explosion -proof fans are widely used in the industrial sphere, they are installed in special exhaust cabinets. Such fans are produced from silomin or stainless carbon steel. Production from a particular material is based on the wish of the customer to have a persistent chemical fan coating or paintwork.
Similar fans are installed in ventilation systems with a rectangular or round section. The explosion -proof fan is equipped with electric motors, a design in the form of an aluminum working wheel with shovels bent forward. Separately, you should pay attention to the fact that such fans are deprived of the opportunity to adjust the speed of rotation.
Such structures, in turn, are divided into axial, roof, radial and channel. We emphasize that all products are divided into ordinary and heat -resistant. The usual can withstand the heating temperature of 800 degrees Celsius and, often used in places of high humidity, have high corrosion resistance. Heat -resistant products are used for gas or air and withstand heating up to 2000 degrees Celsius. For dusty air, airwear structures are widely used, such fans can withstand even strong fires, as they withstand the temperature of up to 6000 degrees Celsius.
In non -channel ventilation systems of insignificant length, an axial fan is often used. To withdraw explosive gases, duct fans are used, installed in production or warehouses. Radial fans, due to a low noise level, you can use public places and residential premises. Roof fans, as it is logical to assume, are installed on the roofs.
When acquiring an explosion -proof fan, it is necessary to pay attention to the availability of certificates of conformity, all the necessary permits. Pay attention to the availability of operating and installation instructions, drawings, working characteristics, descriptions and connection schemes.
Explosion -proof fan fans for air purification in the premises are divided into the first and second explosion hazard class. Not the last place is occupied by the environment in which the fan will be installed. It is quite difficult and not unsafe to choose the necessary product, you need to take into account a huge number of factors and characteristics, therefore it is better to purchase explosion -proof fans based on professional consultation.
