DC AirCube – cleans the air and creates negative pressure in the room if needed Limit values for hazardous particles in the air are constantly exceeded, resulting in a hazardous working environment. By circulating the air through a HEPA filter, class H13, at least 99.95% of particles between 0.15-0.3 µm are separated. The particle size has been chosen because it is most difficult to separate – both larger and smaller particles are easier to separate. Each filter has an individual test protocol. To relieve the HEPA filter, DC AirCube is also equipped with a simpler pre-filter (class G4) to capture larger particles. The DC AirCube can also be used to create negative pressure in a room.
Particles with diameters between 0.1-3 µm are the most critical for the lungs. A large part of these will be stored in the lungs if inhaled. Quartz, Asbestos, PCBs and Cobalt are examples of hazardous and carcinogenic substances with very small dust particles that stay suspended in the air in many workplaces. Air purifiers with HEPA H13 filters also separate viruses, bacteria and pollen particles.
Covid-19 Virus, European Centre for Disease Prevention and Control: ”In buildings where windows do not open and the ventilation system functions in a closed circuit, High-efficiency particulate air (HEPA) filtration should be used for the recycled air. Other options may include, after expert engineering advice: placing temporary HEPA filters over the vents and exhausts in the rooms housing COVID-19 patients or using a portable HEPA air filtration system placed in close proximity to where the patient was located.” (ECDC Technical Report March 2020)
