Filters for air conditioning and ventilation technology clean the air of pollutants, the use of which depends on the effectiveness of particle retention. It is also important that they can bind certain types and types of contaminants.
What is air filtration?
Filtration filtration systems process is defined as the removal of particles from a liquid or gas, and an air filter is a device used to remove particles from a liquid or gas. The physical processes by which particles are trapped in or on the filter are called filtering mechanisms. The mechanism by which particles are separated from the air in a single fiber filter bed depends, among other things, on the following factors: fiber diameter, particle diameter, air flow rate, and particle distribution in front of the filter layer. Filter units have a certain dust capacity. This is the mass of dust retained in the filter per unit area of the filter, accompanied by a condition called filter loading. Therefore, regular maintenance of the system in question and replacement of air cleaning filters are essential.
What are filters for ventilation systems used for?
Air filters indeed play a very important role in the entire ventilation system. As a result, the speed of the air flow and the correct operation of the individual components are affected and the accumulated dust is preserved. They are used in both supply and extract air systems. This protects the devices from contamination such as dust, microorganisms and germs in the room air, which often poses a hazard to individual components. For each filter, there is a specific area for particle retention so that it is precisely matched to the respective ventilation system. For example, depending on the classification, the filter insert traps large particles and is therefore used right at the beginning of the system. This captures even microscopically small impurities very effectively. Depending on the type, each filter also has an expiration date. The air filter should be serviced and replaced regularly to ensure it functions and does not interfere with the proper functioning of the entire system. Filters in warehouses, hotels, restaurants, industrial facilities or medical facilities are checked once a year in accordance with legal regulations.
Changing the ventilation filters
Because dirt builds up in the filters, excessive storage can even cause fungus and mold growth. As everyone knows, this is not an environment conducive to well-being and health. Also, a very dirty air filter may not let in as much air as it should. As a result, proper circulation in the room is significantly hindered. That is why it is worth thinking about regular maintenance, namely the replacement of the filter for air conditioning and ventilation technology. Its service life is usually between six months and two years. Even in single-family homes, ventilation should be checked at least once a year. This work is carried out with the help of experienced maintenance technicians or chimney sweeps. On this occasion, the filters of mechanical ventilation should also be changed. When in doubt, you should always follow the manufacturer's recommendations or follow the gravity ventilation guidelines. In rooms with a very high degree of contamination (garage or home workshop), the ventilation must be cleaned much more often with the help of professionals. To the manufacturer of the filters Look!
Cleaning the air filter
A worn air filter is gray and needs to be replaced. As a rule, disassembly is possible without major problems, it is enough to remove them from the insert or dismantle the front panel of the recuperator. Washing the air filter is not a particularly good idea. However, if the dirt is not too large, you can dry it carefully by reinstalling it. Once a year, the ventilation should be professionally maintained. Regardless of the type of ventilation ducts, a thorough cleaning is recommended every few years. Dirt accumulated in the filters encourages the growth of microorganisms. In addition, very dirty fine filters block the air flow in the system so much that they are located behind the fan. in the air channel temperature rise of several degrees. For gravity ventilation, window and door fans should be cleaned regularly. Even in winter, it is important to provide fresh air. For example, windows that are too tight can cause excessive humidity in the home. The ventilation grilles in the bathroom and kitchen can be cleaned with a vacuum cleaner or a brush.
What are the symptoms of a filter not working properly?
Are there problems with air circulation in the building? Do you notice foggy windows, humidity or fan noise every day? This may indicate a fault. If the mechanical and gravity vent filters are not working properly, excessive contamination may or may not be the cause. In addition, you must ensure that the filters in question are suitable for the existing system and have not been installed incorrectly. First of all, leaks and mechanical damage to individual system components must be excluded.
