The insulation class of electric motors
The insulation class of electric motors is an important point to consider when selecting a motor for a specific application, such as fans, compressors, drive motors, in transportation, in light and heavy industry, as it indicates the capacity of the motor to resist electrical and thermal stresses, and therefore allows to predict its duration over […]
The advantages of advanced sleeve bearings fans (H version)
Fans with advanced sleeve bearings in direct current, also known as H version, are part of the Esmeris range of the Fandis catalog and offer numerous pros. In a previous article on our blog, we have already analyzed the difference between the use of ball bearings and sleeve bearings in compact fans. In this article, instead, […]
Cooling: a safe and certified range of fans
When it comes to cooling, fans are usually used to facilitate heat exchange with the environment, in combination with compressors and evaporators. However, the use of new gases in refrigerant circuits places them in situations of potential ignition risk, in the event of leaks. Gases in cooling circuits It has been decades since the global […]
Difference between AC, DC and EC fans
Until recently, there were two types of compact fans, those in AC alternating current and those in DC direct current. Then, the EC electronically commutated fans appeared. Let’s start by distinguishing the different types of fans through the type of power supply used. AC alternating current fans The AC fans work with the alternating voltage and […]
