Dental Air Compressor: What it is & How to Choose it?

08 Apr, 2022

No matter what the size of the dental office, professional dental tools are the secret of a successful dental office. Dental tools play a vital role in patients’ oral health. Among these dental tools, the dental compressor is one of the most important machines. This post covers the introduction about the dental air compressor and how to choose dental products air compressor.


What is a Compressor

The dental compressor is dental equipment that creates high-quality, high-pressure air. This high-quality air would be delivered through specialize lines to dental operatories and is used to run the dental handpieces that the dentists use to clean and treat a patient’s teeth. Generally speaking, the dental air compressor has developed into two main types: oil free air compressor and lubricated dental air compressor. Today, the oil-free air compressor is the most commonly used in dental practice, due to its feature of oil-free.


How Does the Dental Air Compressor Works?

The process of compressing air is similar to the operation of an internal combustion engine. Also, the dental air compressor parts are also similar to a small gas engine. It consist of a head, a piston, connecting rod, crankshaft, and cylinder.

●First: The dental air compressor head draws air in by the downward movement of the piston in the cylinder.

●Second: As the upward movement of the piston, the air also be compressed.

●Third: The increased pressure drives the discharge valve to open, let the air move into the tank.

●Fourth: Much pressure is built up in the tank by each stroke till reaches its capacity. Also, accumulated pressure also controls the switch of the motor.

●Fifth: The two-stage compressor also would follow the above operation with the addition of a second cylinder, which air is pumped into to create greater pressure.

Why is A Dental Air Compressor Important?

To make you deeply understand the importance of the dental air compressor, I would like to say that the dental air compressor is like the heart and lungs of a living being. Therefore, the dentists could not make the surgery without the dental air compressor. Furthermore, dental handpieces require a continuous flow of high-quality, nearly medical-grade air to drive them to run.

How to Choose the Dental Compressor?

Since we have already known the importance of the dental air compressor, how do we choose the right dental air compressor for the surgery?5 factors you need to take into consideration during the selection of the dental compressor.


Quality of Air Output

Clean and high-quality air is the a crucial part of dental surgery, because it is being sprayed directly into the patient’s oral cavity. Furthermore, the unclean air also may cause some health accident. Because of it, the oil free dental air compressor is introduced by dental supply manufacturers for the purpose of solving the problem of the air containing oil. In addition to purchasing a good air compressor, the oil free air compressor maintenance is also important.



Then, when you choose different sizes of the dental air compressor, you also need to pay attention to the power output. The power output determines the pumping air ability of the compressors. Most compressors rate power output either in kilowatts (kW) or horsepower (HP). 1 kW equals 1.34 HP. Generally speaking, the 24l 1.5 hp oil free air compressor is enough for most dental office works.



All dental equipment require specifically the pressure. The pressure requirements are measured in bars, which equal ~14.5 psi each. Most dental tools require pressures of 5 bars. Therefore, it is a wise idea to generate slightly more pressure than each tool requires, in case the lack of pressure.


Size of Practice

The size of your office (number of operatory chairs and practitioners) is the factor that determines the size and number of air compressor you should equip. If everything is not taken into the consideration, your work efficiency would badly be affected by the number of dental air compressors. Typically, the dental products air compressor with a slightly larger capacity for your size has less running time, making less overall noise.



The location of the mechanical or utility room would affect the acceptance of noise of patients and dentists. The location of the mechanical or utility room would affect the noise acceptance of the patients and dentists. Although the oil free dental air compressor could produce cleaner air, the oil free dental air compressor runs noisier than oil-lubricated motors. Then, if you want to get a compressor with less noise, a silent oil free air compressor is highly recommended.


Last Words

All in all, the dental compressor takes a place in the dental practice and a quiet oil free air compressor is a relatively wise option for your dental offices. If you want to know more details about the dental air compressor, you could consult the dental air compressors manufacturer to find the best dental air compressor.
