The use of Roots fan we need to understand the principle of selection of Roots ventilator
Correct selection of ventilators is an important step to ensure that the ventilation system is normal and economic. The selection principle of the ventilator is: firstly, high applicability; secondly, high reliability; thirdly, good economy.
High applicability, meaning that the use of the selected fan, structure, performance parameters are in line with the conditions and requirements of the use of working conditions. If there is no need for fan varieties and machine number, can not be indiscriminate, should require the fan manufacturer to design another.
Strong reliability means that the design and manufacturing quality of the selected fan is in full compliance with the relevant national technical standards. The fan runs reliably and has a long service life.
Good economy refers to the high efficiency of the fan, low energy consumption, low noise, small size, occupy less space, low cost, easy maintenance and repair.
