Efficiency of our smoke evacuation systems

In our webcast you will discover how ULPA filters work and why the IES 3 smoke evacuation system can also effectively filter SARS-CoV-2 viruses and nanoparticles with a very high probability.

According to current knowledge, the particle size of the SARS-CoV-2 virus is between 60 and 140 nm.

We can assume that our smoke evacuation devices effectively filter SARS-CoV-2 viruses with a very high probability:  The main filter cartridge for IES 3 contains a ULPA-15 filter that removes 99.9995% of all particles from 0.1 μm. (= 100 nm). Particles that are smaller than 0.1 μm or larger than 0.3 μm are trapped with even higher efficiency than 99.9995%, due to physical mechanisms like diffusion effect, barrier effect and sieving effect.

Apart from the particle size, filter efficiency is also influenced by the inflow velocity. That means if the volume flow is too high, the filter efficiency is compromised. Therefore, we limited the maximum volume flow of the IES 3 to 300l/min to ensure a reliable filtration performance of 99.9995 % of all particles at each possible device setting.

Further personal protection measures, such as FFP-3 masks, additionally increase the safety of the operating personnel.
