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.
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.
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.
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.
Reduce the need for artificial snowmaking with snow cooling units
Artificial snow sysems secure economic viability in many ski regions. At the same time, they attract criticism due to their high water and energy requirements. Snow cooling units offer operators the chance to reduce their artificial snow requirements while saving costs and resources.
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.
How air purifiers can contribute to improving health protection
The question of whether or not mobile air purifiers reduce the risk of viral disease and can help to improve health protection can be answered with a ‘yes’. That is what the current study by the Institute of Fluid Mechanics and Aerodynamics at Universität der Bundeswehr München has found.
Drying of inorganic powders with vacuum and refrigeration technology
For the manufacture of tools with additive manufacturing (3D printing), very dry metal powder is required. To achieve the required degree of dryness, the powder is dried with a combined vacuum and refrigeration process. The process facilitates effective, even drying at low temperatures. With the aid of a protective atmosphere comprising inert gas, the metal powder can be shielded against the introduction of moisture or reaction with the ambient air.
How powder quality influences printing results
3D printing has developed into a powerful production technology in recent years. Alongside the 3D printing processes based on modelling and photopolymer baths, the powder process has become a commonly used method. Be it metal, plastic, glass, ceramic or composite powder, all powders have one thing in common: their degree of dryness is a key factor for the quality of the printed product.
