Growing demand for high-end air treatment systems drives the global industrial air filtration market. Whether you need to collect process exhaust discharge, smells, VOCs, or corrosive ambient air, there are solutions to your demands. Keeping clean air in your facility is essential for employee health and safety.
Filtration Media
A wide range of filter media materials is available from water filtration and air filter supplier Richmond. The material determines how much contaminant is removed, whether physical capture or chemical adsorption. Some common filter media include gravel to reduce sediment, resin to remove tannins from water and catalytic carbon to reduce chlorine, taste and odor. Reverse osmosis is also an excellent method of eliminating many impurities from water.
Many modern filters use multi-media systems that combine a dense, fine layer of media, such as sand, with a coarser upper layer, like crushed anthracite coal. The rough layer helps remove larger particles before they reach the fine layer, which extends the filter’s life. KDF media is another highly effective chlorine removal option that can be used upstream of a carbon filter to extend the life of the carbon. It’s also cheaper to operate and performs well at higher temperatures.
HEPA
High-quality HEPA industrial air filters are essential to ensuring that your facility adheres to regulatory and industry standards for a safe working environment. These filters can help to prevent the spread of airborne bacteria and microbes that can cause illnesses in your employees. These filters, known as HEPA filters because of their ability to trap airborne particles as small as 0.3 microns, stand for “High-Efficiency Particulate Arrestance.” These microscopic pollutants include pet dander, smoke, pollen, mold spores, and other common allergens.
When a HEPA filter works correctly, it can trap these particles using three mechanisms. The first is called diffusion, wherein the particles collide with gas molecules and are delayed in passing through the filter. It can make it easier for them to stick to fibers through interception or impaction. Pharmaceutical clean rooms, for instance, are required by regulations.
ULPA
HEPA filters work well in industrial applications, such as pharmaceutical and biomedical manufacturing and clean rooms. In these environments, it is crucial to preserve the quality of products and materials from contaminants like airborne bacteria and viruses. ULPA filters are similar to HEPA because they contain filter material folded into a frame and can catch small particles from the air that passes through them. These filters achieve high levels of filtration by limiting the speed at which air can penetrate them and using multiple trapping methods, including diffusion, interception and inertial impaction.
Another advantage of ULPA filters is that they can handle higher concentrations of salt and chloride. It’s important for oil & gas environments and helps protect against costly downtime caused by corrosion. Unlike HEPA, however, ULPA filters do not remove gases, fumes and odors. Additional pre-filtration may be necessary for these types of environments.
Poly/Cotton
Cotton is a natural fabric from nature, making it comparatively eco-friendly and breathable. Polyester, on the other hand, is a synthetic material that is derived from petroleum products. Combining the two materials results in a breathable and durable fabric that’s also affordable. Polycotton fabrics are a popular choice for medical scrubs because they offer the best of both worlds – softness and breathability. In demanding work environments where employees get hot and sweaty, it’s important for their clothing to absorb moisture. The percentage of cotton and polyester used in the blend varies depending on the desired properties of the final product. Still, the combination of both fibers provides a lightweight yet sturdy fabric. These fabrics are also available with added features such as flame resistance (FR), static electricity reduction and UV protection. They can be further enhanced with technologies like nanotechnology, which allow them to perform better than they would.
