Filters are designed for use in ventilation, air-conditioning systems to clean the air from air pollutants. Filters trap dust, solid particles circulating in the air as well as protect the ductwork from unfavorable weather conditions. They vary in rating depending on the degree of air cleanliness that the density of the filtering material ensures. SanTech manufactures G4 filters which guarantee a high level of air quality.
The company also offers simple mechanical filters which remove dust and solid particles by capturing them on fine sieves. They are used in case there is no need for highly efficient protection, however, primary air filtration is desirable.
