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.
Atlantic Blowers is proud to announce that we have finally added centrifugal fans to our selection of products. Adding this product line allows us to expand our capability to meet higher flow demands. centrifugal fans are broken up into 4 family types: ABCF-100 series, ABCF-200 series, ABCF-300 series, and ABCF-400 series, respectively. Because of their high airflow capacity, centrifugal fans are perfect for numerous industrial environments such as: laboratories, commercial buildings, restaurants, automotive stations, factories, and home ventilation.

Atlantic Blowers Tube Axial Fans are durable, versatile, and cost effective. Our tube axial fans consist of an outer metal housing and a cast aluminum fan directly coupled to an explosion proof motor (standard). Depending on the size, our fans come foot mounted with a portable handle, or caster-mounted making them easy to maneuver. One of the more prefereable features in an axial fan is it's power to performance ratio. These fans are incredibly efficient when it comes to moving air volume. For example, an 8" diameter fan can move 1942 CFM with only a 0.5 HP motor! This is achieved because of the axial fan's unique design.
