Best Dental Compressors for 2022

The quality of dental services provided directly depends not only on the experience and professionalism of the doctor, but also on the technical equipment of the dental office.

The doctor's working instruments are powered by a unit with a compressor that injects compressed air into them under pressure. Such an installation is quite expensive, therefore, before choosing a specific modification, it is necessary to compare popular models not only in terms of price, but also in terms of functionality, scope, main characteristics, power, noise level, and other parameters.

Criteria for choosing a dental compressor

In order not to make mistakes when choosing an air flow generator, you need to understand the basic principles of the device. The compressor motor is driven by pistons similar to those used in automobile combustion chambers. Early modifications of such engines worked with the use of oil, which could enter the environment with air.

Over time, such motors were abandoned, and now oil-free piston groups are used in dentistry. The principle of their operation is based on forcing air into the receiver in the process of closing and opening the piston in the cylinder, while grinding is done “dry”. In order for the pistons to work without oil, they had to be modified. So, the cylinders themselves began to be produced from a more resistant material - cast iron, and a special cooler was designed to reduce the temperature that rises when parts of the apparatus rub against each other.

The air pumped by the compressor is used at all stages of the operation of the dental unit - the operation of the turbine in the handpiece, the supply of a compressed air mixture for dust blowing, the suction of saliva from the patient's oral cavity.

What to look for when choosing a compressor:

1. Piston type. As previously mentioned, oil aggregates can release oil particles into the atmosphere, which then enter the human lungs. To prevent air pollution, carbon filters are installed on such devices. In order to keep the air clean, they need to be cleaned periodically or changed as needed.Oil-free devices are characterized by increased wear due to the fact that the rubbing parts are not lubricated. They also make a lot of noise. However, these shortcomings are leveled by a pure air mixture without impurities, safe for human health.
2. Noise level during operation of the installation. The maximum allowable value is 80 dB. Devices made using modern technologies give an average value of 60-65 dB. If such parameters still do not suit the buyer, you can purchase a noise-absorbing cabinet that will reduce noise to a minimum value of 40-50 dB.
3. Operating pressure. This parameter is measured in liters per minute. Since one compressor can be used not for one, but for several dental units, it is important to calculate this figure correctly. Since such dental equipment can be used to power several consumers at the same time, the consumption of each of them must be summed up to select the device of the required power. The approximate flow rate of the turbine is 30-40 l / min, saliva ejector - 20-50 l / min, water-air gun - 11-20 l / min. Since no compressor head is capable of supplying an air mixture to different consumers at the same time with different parameters, a receiver is built into the unit.
4. receiver volume. The receiver is a tank that is filled with air mixture until the required pressure is reached. It is from it that the air is distributed to all consumers. In order to maintain the required pressure in the chamber, it has a special sensor, at the signal of which the pump refills. When choosing a receiver, the first thing you should pay attention to should be the coating material of the tank.To prevent rust, the tank must either be made of stainless steel or be enameled on the inside. For small medical institutions, a receiver will be enough, which is completely filled with a compressor in 3-4 minutes.
5. The presence of a filter. Almost all modern compressor units are equipped with multi-layer filters with the function of retaining dust and oil particles. The better the filter, the cleaner the atmosphere in the room will be. This element is mandatory in oil devices, which are characterized by the release of fine particles of liquid.
6. The presence of a dryer. The air mixture has such a parameter as humidity, which directly affects the rate of hardening of the filling material. The higher the water content, the more difficult and longer the hardening processes occur. Dryers are used in compressor units to reduce humidity.

It is necessary to choose a compressor installation based on the scope of use. A small dental office will only need one compressor and receiver. For the department of dentistry, which includes two or more workplaces, it is not rational to buy several units. The best option would be to install one powerful device, which, through the wiring, will supply the air mixture to all workplaces. The unit must include several heads and receivers for efficient operation. Compared to buying several devices, this option has a number of advantages: budget price, inexpensive maintenance, reliable operation (if one of the heads fails, the rest remain in working order).Among the shortcomings, one can single out an increased noise level, as well as the possibility of incorrect calculation of the required power, due to which the device will not be able to provide all the necessary consumers.

Tips and Tricks to Extend the Life of Dental Compressors

Caring for air mixture injection devices is simple and does not require special skills and knowledge.

Weekly need:

• remove condensate that has accumulated in the receiver - this is easy to do by draining water under low pressure (up to 2 bar);
• remove liquid that has accumulated in the condenser.

Once a month you need:

• check all connections for tightness;
• check that the operating pressure corresponds to that stated in the operating instructions;
• carry out wet cleaning of the condenser and radiator (due to the accumulation of dust, they give off heat worse and cool the unit more slowly).

Once a year is required:

• check the cleanliness of the inlet filter (if the contamination is not strong, clean it; if the dirt is not removed, the cleaning cartridge needs to be replaced);
• turning off the device, check the tightness of the ring on the outlet valve;
• check the functionality of the safety valve (it is enough to press it during operation of the device and evaluate the result of the action by the noise of the exhaust air).

Calling a specialist is required in the following cases:

• during the operation of the device, a loud noise is heard, vibration has increased;
• the pressure in the working chamber is gaining more slowly than usual, or the device does not reach the working pressure;
• fans in the cooling system do not work;
• the unit spontaneously turns on at a time when none of the consumers is active;
• the device is too hot;
• the device does not turn on.

Mercury HK-1EW-30

One of the most budget models made in China. Like others discussed in this article, it works on oil-free technology. Instead of oil, a special polymer with a reduced coefficient of friction is used in the piston group. This technology prevents harmful substances from entering the air and provides the required sanitary conditions. The compressor is capable of serving only one unit.

The mini system consists of a compressor, an air tank, pushbutton switches, piping, a fine filter and an air valve.

The unit is equipped with a drain valve that releases excess air when the pressure rises above the set value. There is a built-in pressure gauge that displays the current value of the pressure in the tank. The air filter is installed only at the inlet. The legs of the device are equipped with soft shock absorbers that prevent it from moving on the floor.

When the compressor is running, moisture is formed, which is collected in a special container.For efficient operation of the catchment system, it must be cleaned at least once a month. With the same frequency, it is recommended to clean the air filter, which eventually becomes clogged with dust, which leads to increased energy consumption and poor filtration. Maintenance is recommended to be carried out only by qualified personnel: every 2-3 months you need to wipe the dust from all elements of the device, check the reliability of the connections, check for contact in the grounding cable. The device can only be used indoors at a temperature of 5 to 40 °C.

Conclusion

When choosing a compressor for a dental office, it is recommended to make a preliminary calculation of the performance of the existing equipment, while providing some margin. The higher the performance of the compressor unit, the more it will be able to serve, and the less load will fall on one cylinder.

When choosing a specific model, it is worth focusing primarily on technical characteristics (such as performance, noise level, number of units serviced, etc.), and only then on cost.

We recommend that you choose instruments with oil-free technology. Combined with a good filtration system (at a minimum, a filter is required at the tank inlet), this will keep the air clean at the required level. Another important parameter is the presence of a dehumidifier that removes excess moisture from the air, since high humidity is a significant hindrance for the high-quality hardening of the filling material.

If the dental office is small, you should also take into account the dimensions of the compressor. Since there are a large number of modifications on the market, you can pick up a device of almost any size. There are also mobile models that allow you to remove the compressor to another room, if necessary.

We hope that our article will help you make the right choice and buy the right unit at the best price.
