To remind you, fans are devices that provide air flow by creating a pressure difference. They work by suction from the motor part and blowing from the fan part. There are two <a href=\"https:\/\/blog.kampa.com.tr\/en\/fan-usage-areas-and-types\/\" target=\"_blank\" rel=\"noreferrer noopener\">types of fans<\/a>, axial and radial.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"fan-secimi-yapilirken-4-parametreye-dikkat-edilmeli\">4 Parameters to Consider When Fan Selection<\/h2>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Required air flow rate<\/li>\n\n\n\n<li>Pressure losses<\/li>\n\n\n\n<li>Acceptable sound level<\/li>\n\n\n\n<li>Electrical power connection type<\/li>\n<\/ul>\n\n\n\n<p>The air exchange required for the environment to be ventilated is important in fan selection; it is related to the intended use of the environment, the number and activities of the living beings and objects in it.

Where will the fan be installed? Ceiling, wall, chimney or ventilation pipe.<\/p>\n\n\n\n<p>Another issue is the voltage of the electricity to be connected to the fan. Since our example is based on an office, let&#8217;s proceed with the fan selection from there. Fans are usually mounted on the wall or glass in offices. Since household electricity will be used, a single-phase fan should be preferred.<\/p>\n\n\n\n<p>So I need an axial, single phase, glass or wall mounted fan with a flow rate of 795<sup>m3<\/sup> \/ hour. Let&#8217;s analyze the graphics under the products.<\/p>\n\n\n\n<p>When I evaluate these two images, the first thing I have to decide is whether it is a wall type or a window type. Suppose I choose a wall type fan. The air flow rate I needed was 650 + 145 =795 m3 \/ hour.<\/p>\n\n\n\n<p>In this context, the most suitable fan for me would be the D 25 model with a flow rate of 800 m3 \/ hour.
