An efficient ventilation system is essential for any quality business, but they come with so many separate components it can be difficult to know where to start. As all systems are made up of fans and blowers, the best place to start is knowing the difference between common fan types.
Regenerative blowers have many surprising applications that you may not know about. They're used in a wide variety of industries, from medicine, to manufacturing, to waste processing, to food processing. These low-maintenance machines are especially helpful in the lattermost industry; food processing and packaging relies heavily on several types of fans and blowers. Read on to learn more about the use of high-pressure regenerative blowers and fans in food processing.
The earliest mention of centrifugal fans was in 1556 by Georg Pawer in his book "De Re Metallica," which explains how centrifugal fans were used to ventilate mines. This type of machine was essential during this time period to help keep mine workers safe on the job. However, shortly after this period, centrifugal fans fell into disuse, and this technology remained largely unutilized for several centuries.
In the early nineteenth century, pressure blowers started to appear in several different industries once again. This slow growth in The Marquis de Chabannes began advocating for their use 1815, taking out a British patent that same year. Meanwhile, in America, pressure blowers began to be used for steamships. In 1827 in New Jersey, Edwin A. Stevens used a pressure blower to blow air into the boilers of the steamship North America . A similar installation was done in 1832 by Swedish-American engineer John Ericcson. Shortly after, in 1832, a Russian engineer designed a centrifugal fan to be used in a wide variety of industries. This design is the basis for modern-day centrifugal fans.
Modern Day Applications
Currently, pressure blowers, axial fans, and centrifugal fans have applications in many different industries. Today, they are frequently found in food manufacturing and processing, where knife blowers are used to dry products before final packaging and regenerative blowers are used to move fragile food items. Additionally, regenerative blowers are used in waste management, dentistry and medicine, and even in modern spa systems.
Overall, these fascinating, low-maintenance machines have greatly impacted industries across the world for centuries. As technology develops, these machines will see greater use and wider application far into the future.

A typical restaurant already holds a maze of contaminants in its food preparation and in the cleanliness of its employees that handle the food. Another important aspect of a restaurant's cleanliness is its ventilation system. Installing proper ventilation systems with high pressure centrifugal blowers and cooling equipment is as important for a restaurant as following food preparation procedures.
Across all sorts of industries, air handling typically needs to be high-quality and low-cost. That's often why centrifugal fans are the ideal choice. Because centrifugal fans can be produced quickly and easily, this often saves businesses on production costs. Also, because they produce a truly steady airflow, your business won't ever have to compromise on quality. But what are some other reasons centrifugal air blowers are often the go-to choice? We'll discuss their benefits in today's post.
What is an air knife blower and what is it used for?Air knife systems discharge pressurized air in order to clean and/or dry a given product, typically in a conveyor belt setting. They're used to blow off liquids, dust, and debris from a material's service prior to packaging. They can also be used to cool down a product's surface. Air blower manufacturers can produce air knives with slightly different appearances, but they are made of metal, are relatively thin, and resemble half-cylinders.
How to air knife blowers work?Generally speaking, air knife blower systems are considered to be one of the best methods of removing unwanted substances from product surfaces. Although most are used in conjunction with a conveyor belt, some systems actually have mobile air knife blowers that remove foreign substances from products that remain stationary during this process.
Regardless of the setup, the process is essentially the same. There are two basic types of air knives: those powered with compressed air and those powered with blowers. Compressed air knives are generally not thought to be as efficiency as those powered with blowers. With blower-powered air knives, a high-speed, centrifugal blower delivers pressurized air to the air knife blower through a connective pipework system. Then, the air knife blowers discharge that air, which combines with the product and removes debris or liquid from its surface. It's a relatively simple process that is highly effective and fast.
What should I do if I need air blowers for my business?The good news is that air blower manufacturers have all sorts of air knife blower models to choose from, all with a variety of lengths to offer. That said, selecting one can feel overwhelming. That's why it's best to contact your air blower manufacturers with any questions or concerns you may have. With their help, you should be able to decide on the precise model that will fit both your needs and your budget.

- Location: The environment in which a centrifugal system operates will make a huge difference as to what type of blower is needed. Hazardous environments, for example, will require you to prioritize a non-sparking model (such as a fully aluminum blower) from your industrial blower manufacturers. Those who work in particularly dusty environments may need to give careful thought to the type of motor they choose, as certain models may have shorter lifespans when there's excess debris. In these situations and in outdoor environments, a TEFC (Totally Enclosed Fan Cooled) electric motor may be appropriate. Stainless steel blowers are best for those working in particularly humid locations. Keep in mind that the air temperature can impact the type of model you select from air blower manufacturers, too. In higher temperatures, belt drive blowers with steel wheels or industrial blowers with heat slingers often work best. You may need to consult with your air blower manufacturers to hear their specific recommendations for your environmental concerns.
- Air Quality: This one goes hand-in-hand with the previous consideration. But the air quality in your environment matters a lot. Even the type of dust might impact your choice of blower. If the air is only mildly dusty, a backward inclined blower might do the job, though a high-pressure or radial blower may also be appropriate. Heavier amounts of dust in the air may call for a blower built to handle industrial materials. As we mentioned earlier, air with combustible materials or excess humidity will require different types of blowers.
- Pressure Needed: Centrifugal blowers can be geared either more towards pressure, or towards producing more flow (air volume). But before you choose, you'll need to know a bit more about your air duct system and how much pressure you need to achieve your goal. Complicated duct systems usually require blowers with more power. Smaller blowers are often direct drive models, which are generally more efficient and reliable, are less complex to assemble, and don't require as much maintenance. But belt drive blowers are bigger and more flexible. You'll want to take a close look at your duct system to ensure the type of blower chosen will live up to your expectations.
Choosing the right centrifugal blower for your needs may seem a bit complex, but we're here to help. Please contact us today with any questions you might have or to learn more about the models we have available.
- Rotating Blades May Cause Injury
All industrial fans and blowers contain rotating drive components or blades. If caution is not taken in proximity to these blades, injury can occur. Both direct and indirect contact with propelling blades can cause harm to an individual. Guards surrounding the blades should never be removed unless the unit is de-energized. It's important to lock, tag, and test the system to ensure this has been done prior to inspecting or doing any work on a fan. Otherwise, serious physical injury can occur. It's also important to wear proper eye protection and respiratory protection and to take care when walking around these fans. A strong wind can cause propeller rotation even when units are non-operational, which can lead to blowing dust. It could also cause the propeller blades to move through force, which could cause injury or knock an individual on the ground. To prevent this possibility, individuals must maintain a safe distance from the fan's wheel at all times and the propeller must be secured.
- Hot Surface Areas Can Cause Burns
Regenerative blower manufacturers will point out that their equipment is considered to be contact-free; they're able to operate for up to 40,000 hours without the need for service. But that's not the case for every blower out there. Some fans do need to be handled more frequently. However, because of the materials used and the mass of this equipment, it's vital to remember just how hot these fans can get. Even after they are de-energized, fan motors can retain their heat for long periods of time. Don't assume that shutting off the blower will offer an immediate cool-down period. They can maintain temperatures in excess of 220 degrees Fahrenheit long after they're shut down. That's why when you are asked to maintain or even stand in close proximity to centrifugal fans, axial blowers, or other equipment like this, you must be mindful and take steps to prevent injuries. Give these elements enough time to cool down before commencing work on them or touching them.
- Loose Parts Could Be Disastrous
Centrifugal air blowers, air knife blowers, and other fan systems are meant to stand the test of time. However, no piece of machinery can last forever -- particularly if it is not properly maintained. There have been rare occasions in which internal components of an industrial fan have malfunctioned or dislodged in some way. To prevent this from occurring, these fans must be maintained on a regular basis and inspected thoroughly before operation. If you have a loose blade or other part and the fan is turned on, serious injuries and other problems could occur. Make sure to have all centrifugal air blowers and other fans installed and maintained by trusted professionals.
