One of the main reasons, why the need to install filters - is the need to supply air purification, which is always in the ventilation and air conditioning systems. The bag filter is installed in shopping malls, airports, large office buildings, business centers, etc.. d. Inlet air filter cleans both the shallow, and coarse dust. Today, relevant not only pocket filters. have rolled, tape and other types of. but definitely pocket filters more in demand. Since they have a serious area of material. For this reason, the filter can last for long and uninterrupted.
If you explain in simple terms exactly, without pocket filters in large rooms the level of particulate air pollution would be very serious. Of course, Filters are constantly faced with the enormous load - their working conditions can not be called soft. But thanks to the ventilation filter other elements are used for a long time. To those elements include the fans, and, eg, heat exchangers. Thus, if there is no filter in the ventilation system, its service life is reduced. Therefore, it is not installed and used only for the sake of clean air.
