Dental Air Compressors: Choosing the Right One

Comments Off on Dental Air Compressors: Choosing the Right One

Every day, dental practices rely on air compressors to provide safe and comfortable services to their patients. However, new air compressors can be a serious investment for most practices, making it essential to select the right one for your office.

Three main factors go into choosing the right air compressor for your dental practice:

  • Power: Most dental offices require compressors to operate between one and five horsepower to efficiently run their equipment
  • Pressure: Each dental tool necessitates a specific amount of pressure to run properly, and air compressors must provide enough pressure to safely operate all your tools simultaneously
  • Production: Make sure your compressor choice exceeds your practice’s required cubic feet per minute (CFM) or liters per minute (LPM) ratings to ensure it can easily handle your dental equipment and accommodate new additions as necessary.

What to Consider When Choosing a Dental Air Compressor

The above considerations govern selecting the compressor with the right physical attributes for your practice’s needs. Some of the most important decisions that factor into optimizing your air compressor’s power, pressure, and production levels include those concerning:


You should consider both the size of your practice as well as the desired size of the air compressor in relation to it. Most dental air compressors measure output in one of two ways:

  • Cubic feet per minute (CFM)
  • Liters per minute (LPM)

Dental chairs typically require 50 LPM or 2 CFM of air per chair. Additionally, you should account for the number of personnel who regularly use your equipment, as too much simultaneous use could strain a system that’s not prepared for it.

Use of Oil

Most dental environments benefit from using oil-free compressors. Oil-based compressors risk contaminating surrounding fluids, which could imperil patient health. Oil-free air compressors also require less maintenance and upkeep because they work with less volatile substances.


Most compressors rate power output either in kilowatts (kW) or horsepower (HP). 1 kW equals 1.34 HP.

This power range governs a compressor’s ability to pump air. Dental air compressors come in a range of power ratings, but for most dental offices, compressors with 1–5 HP (~0.75–3.7 kW) get the job done.


All dental air compressors run on motors. The motor runs the compressor, and the compressor has one or two pistons depending on the model.


All dental tools have specific pressure requirements. Many measure their pressure requirements in bars, which equal ~14.5 psi each. Most dental applications use pressures of 5 bars, but to avoid straining your equipment, it’s usually a good idea to generate slightly more pressure than each tool requires.

Using Air Compressors for Food and Beverage Applications

Comments Off on Using Air Compressors for Food and Beverage Applications

The importance of using air compressors for food and beverage processing applications cannot be overstated. Many steps of the manufacturing process benefit from the use of compressed air, such as:

• Food mixing
• Packaging movement
• Pumping fluids
• Air filtration

This last step is arguably the most important role of air compressors in the food and beverage industry. Filtering out contaminated air is essential to creating sanitary food products, helping you preserve customer health and avoid liability.

For this reason, air compressors used in food manufacturing environments must be held to the highest standards. For example, if your processes fill a ready-to-eat package with contaminated air, the dirt or bacteria in that air will travel directly to your customer. This poses a risk not only to them, but to your business as well.

Therefore, choosing a dependable, efficient, and oil-free air compressor for your manufacturing application is vital for ensuring that you deliver the highest-quality products possible. Here, we outline a few of the ways you can best incorporate air compressors into your facility.

Applications for Food and Beverage Air Compressors

Compressed air is a powerful tool for many different applications within the food and beverage industry. Imagine a hypothetical manufacturing facility that uses compressed air for the production of yogurt. In one area of the factory, compressed air pushes flavoring powders through tubes to mix them with uncultured yogurt. In another area, compressed air supplies oxygen to the yogurt as it cultures. Once the yogurt finishes culturing, additional processes place it into containers cleaned using compressed air. Throughout these automated process, the air also opens valves and actuators for filling and bottling.

Although this is only one example of the use of compressed air in food processing, this technique can benefit food processing applications in many different ways. Air compressors can spray oil and dispense liquids such as soft drinks, condiments, or beer. Compressed air generators can produce ozone to treat water or to generate nitrogen to create nitrogenized beer. The air can be used directly on the food as an air knife or on the packaging for agitation, transfer, or sealing.

The uses for food-grade air compressors are almost endless. Some other applications for air compressors include:

● Bakeries (to spray vegetable oil)
● Coffee automats
● Packaging
● Mixing foods
● Pilot air

Uses for Food and Beverage Air Compressors

Because of the wide range of pressures that air compressors can generate, they can be used in many different places on your product line. Here are just a few examples of how food and beverage processors use air compressors every day:

• As raw ingredients and materials enter a factory, compressed air sorts them based on weight
• High-pressure compressed air peels and slices fruits and vegetables such as carrots, onions, and apples
• Worker use compressed air to wash down packaging machines and keep the factory sanitary
• Compressed air pushes fillings into pie crusts or other stuffed pastries
• Diaphragm pumps move around the liquid filling to ensure even distribution
• Low-pressure compressed air blows off crumbs from baked products
• Workers use blow-molding to create specialized packaging
• Compressed air cleans packages and vacuum seals food products inside
• Cold compressed air freezes products for shipping and retail

As you can see, compressed air is integral to every step of the manufacturing process in the food and beverage industry. Because of its usefulness, some people call compressed air the fourth utility, saying that it is just as important to manufacturing as running water, heat, and electricity.
