STANDARDFRIGOR  deviro air purifier AF650

The deviro cleans room air of fine dust, viruses and other elements that are harmful to health using a three-phase filtration system. The downstream HEPA H14 filter removes 99.995% of impurities from the air. Despite its powerful fan, the derivo is one of the quietest filtration devices in its class and can therefore also be used in work rooms.

Fields of application

  • Areas with a high turnover of people, such as supermarkets, fitness studios and restaurants
  • Noise-sensitive environments such as work rooms, control stands, offices, meeting rooms, technology control centres and medical practices
  • Industrial applications such as production areas and electronics rooms with personnel

For decades, we have implemented sophisticated air-conditioning and air filter solutions in various industrial sectors. Benefit from our experience and read interesting know-how on filtering viruses and fine dusts in our articles.

Why winter is favourable to coronavirus and weakens the immune system

Many types of viruses thrive in favourable conditions in winter. They can survive for long periods in the dry, cold air, and people spend more time indoors. On the other hand, our immune system weakens due to the dry air and lack of sunshine. This combination makes coronavirus and other pathogens more dangerous in winter than in summer. However, humidifiers and air purifiers can help to keep us healthy throughout the cold months.

Powerful, thorough, quiet: How do air purifiers work?

The filter and fan of an air purifier determine the type and quantity of pollutants it can remove from the room air. Other features such as noise emissions provide information about the locations for which an air filter device is suitable.

Correctly positioned air purifiers complement regular airing

The viral load of indoor air can be significantly reduced by regular airing combined with the use of air purifiers. These also make it possible to remove coronaviruses, fine dusts, and bacteria, even in rooms without windows, and in crane driver cabs. In order to achieve an even distribution of purified air, some rules should be observed when setting up an air filter device.

HEPA Filters: Using physical tricks to capture particles

HEPA filters are among the most efficient mechanical filters and remove up to 99.995% of contaminants from the air. They rely on the movement characteristics of different small particles to do so. Based on standardised filter classes, inefficient HEPA filters are easily distinguished from HEPA filters that are actually effective.

Why room air hygiene should also be given priority after Corona

The Corona pandemic has abruptly brought home to us how air in indoor spaces is often contaminated and dangerous to health. Air purifiers protect us from viruses, fine dust, mould spores and other airborne contaminants that will continue to affect our health and well-being after the current pandemic has been contained.
