Easy to say, ULPA is an acronym for "ultra-low particulate air." An ULPA filter is designed to remove at least 99.999% of dust, pollen, mold, bacteria and any airborne particles with a size of 100 nanometers or larger from the air. ULPA filters are made of a spun-hooked glass fiber, rolled into a paper-like material, which is then pleated, increasing the filter's surface area. They are also available in a wide variety of sizes and styles including wood board, galvanized, aluminum and stainless steel frames. Here is a brief introduction about ULPA filters design.
High efficiency is so important in ULPA filters design. Efficiency is the ability of HEPA filters & ULPA filters to remove a certain amount of particles of a certain size with a specific airflow. ULPA filters screen particles larger than 0.3 μm and are 99.9995% efficient in removing particles that are 0.12 μm and larger. When these high efficiency filters are used with a pre-filter, they can last for several years in a cleanroom environment. In addition to this, because airflow capacity will decrease and the static pressure will increase with time, ULPA filters have the ability to become even more efficient as the filter loads.
HEPA & ULPA Filters are used widely in air filtration and purification systems to control airborne particulate levels and to stop the spread of toxic agents or infectious diseases. HEPA & ULPA Filters are ideal for use in many areas including: semiconductor manufacturing, pharmaceutical processing, research laboratories, electronics, food processing, and medical device manufacturing. Especially, in ULPA filters design, ULPA filters are often used in HVAC systems, biological safety cabinets, laminar flow hoods and various healthcare facilities worldwide. Laminar flow hoods are not designed to control infectious diseases or toxins, but medical facilities such as isolation rooms, Intensive Care Units (ICU's), and surgical centers. Operating rooms also use ULPA filters to remove infection and contamination by airborne microorganisms such as viruses, molds, and spores.
Specially designed for use in cleanrooms and precision assembly areas, ULPA filters come in a wide range of sizes for many applications. They can also be used in final-filtration applications with purification filters. The filtration medium consists of highly efficient micro porous polyurethane mini pleats that are held in place with rigid plastic separators that keep the filter medium from nesting together. The design channels the air flow with optimal efficiency and reduces resistance. The Bag filter is sealed into a sturdy aluminum frame with a fire-retardant adhesive.
Since different processes of air filtration and purification need different levels of air cleansing and purification, these factors should be taken into consideration in ULPA filters design. If you are in need of HEPA & ULPA Filters, you can visit www.hefilter.com for more information.
