87 optimized pleats structure together with German Hankel hot melt to form more than 400 stable filter sections, gives unfolded area about 2.3 m^3. High grade filter seal enabling the filter assembly firmly and guarantee the sealing, not only prevents leakage and ensure all air flows through filter, but also reduces noise.
Special layerd media provides the combination of specific filtration technology targeting large range of particle sizes. Mechanical & inertial means captures bigger particles, which are more than ~0,5 micron, and diffusion & electrostatic mechanism effectively captures ultra fine particles as small as 20nm.
