Air Blower Uses and Industrial Applications

There are many air blower uses in the industrial processes that require compressed air with a comparatively low operating pressure of about 0.3 to 4 bar. In this range, we name it low pressure.

Low pressure blower and compressor technologies are used in a variety of applications for an array of purposes in the Middle East. For example, low pressure technology is used for pneumatic conveying processes in cement factory; for the aeration of clarifiers in the sewage plant; for creating bubble curtains in a fish farm etc. Let’s explore how different industries use air blowers for critical processes.

In the wastewater treatment industry, plants treat wastewater using aerobic biological processes to digest waste by-products. In other words, millions of bacteria feed on organic waste, breaking it up into carbon dioxide, nitrogen gas and water. Because bacteria need oxygen, large amounts of air are blown into aeration tanks. This process requires continuous operation of air  blowers and a reliable, steady flow of clean, 100% oil-free air.

Whether it’s helping to guarantee water quality, installing an efficient feeding system, creating a protective bubble curtain, or moving live organisms from one place to another, the aquaculture industry deals regularly with air blower applications that require compressed air or oxygen. Many of the processes within the cultivation of fresh or saltwater populations of organisms such as fish, crustaceans, and mollusks are dependent on the delivery of Class 0-certified clean, oil-free air or in case of dense populations - oxygen generators.

The moving, mixing, heating, and cooling processes of cement manufacturing [link to cement industry page] are achieved through the use of blower technology. From pneumatic conveying and combustion air to cooling air and aeration, many processes wouldn’t be able to take place without low-pressure equipment.

In coal-fired plants, where the burning of fossil fuels results in the release of sulfur dioxide, low pressure blowers are used to remove sulfur dioxide from the exhaust flue gases. The resulting process of flue gas desulfurization helps meet government requirements for reducing emissions. Since coal-fired plants must be up and running 24/7, the plants use air blowers that can provide the correct amount of air based on demand, with virtually zero downtime.

Low pressure, oil-free blowers play an integral role in the food and beverage industry. The main subsegments that use low-pressure air for numerous applications in this industry include meat processing, poultry, dairy product manufacturing, preserved fruits and vegetables, as well as brewing and beverage processes. The primary use of low-pressure air in this market is pneumatic conveying in both vacuum and pressure. Many food manufacturers use air blowers to operate wastewater treatment facilities independent from their municipalities to decontaminate process or sewage water and to treat organic waste.

Oil-free air solutions for the textile industry are used in applications such as adjusting the flow in order to influence fiber characteristics, aerating the water used during the production of textiles that must be treated before it can be released back into nature, pneumatic transport of fabrics, and PET chips.

These air blower machines play a key role in powering petroleum refining, or the variety of processes employed in converting crude oil into useful products, including gasoline, kerosene, jet fuel, and diesel oil. Within petroleum refining, sulfur recovery and thermal incineration/oxidation are two of the key processes powered by low pressure blowers.

Many manufacturing processes use dilute phase pneumatic conveying to transport any dry bulk materials, including powders, granular forms, and chips and pellets. A reliable stream of low-pressure oil-free air is essential to keep the production running smoothly. And because manufacturing plants that use pneumatic conveying have employees working nearby, blowers that utilize low noise and low vibration technologies are necessary for worker’s safety.

Energy consumption typically takes up to 80% of a blower’s total cost, so saving energy is incredibly important when it comes to the industrial air blower uses. There are different types of low-pressure blower technologies available to the industrial plant operator, categorized as lobe, screw, centrifugal, and multistage options. Choosing the right air blower technology for your applications will assure the reliability and performance of your equipment in order to maintain continuous operation in the factory.
