Air Filtration Systems
Air filtration systems describe a wide variety of equipment used to remove impurities from the air with a number of different filtration and purification schemes. Air pollution, which can be invisible to the eye, is not uncommon and ranges from dust and pollen particles to microbes, gases and chemicals. Although widespread, air pollutants can trigger serious allergic reactions and promote the spread of airborne disease. Industrial, commercial and residential buildings are often required to have an air filtration system of some sort and filters are commonly incorporated in heating and cooling appliances. Aerospace, computer, food and medical industries all rely heavily on air filtration systems to promote health and maintain product functionality as particulates can clog important equipment.
In general, most air filtration systems use an electronic blower that pulls or pushes air through a filter, or several, and then releases the purified air back into circulation. A filter is a mat or barrier made of fibers through which air, but not particulates, can pass. These panels are most commonly composed of fiberglass and mesh type materials, though there are many factors involved in choosing a filter. Porosity, efficiency, filter length, height and width or ring size, and ply vary greatly among the many air filtration systems and should be considered with relation to purification needs. Alternatives to conventional systems include ion diffusers, which neutralize the air, and ozone air filtration products, which destroy rather than trap particles. Air filtration systems range from portable residential products to fixed industrial set ups to suit all filtration and purification needs.
