evaQvent AB was started in 2019 by Gunnar Johanson and Urban Svedberg. After several years of research on the risks associated with unpacking of contaminated shipping containers, we developed a method and tools to facilitate pre-ventilation. The arrival concentrations of harmful levels of chemicals can be reduced by 90% within 4 hours, often faster. We now offer a complete package with extraction fan, suction hoses and our own evaQplate, the device that attaches to the container.
