Best Dental Compressors for 2024

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

Selection criteria for 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 engine is driven by pistons similar to those used in automobile internal combustion chambers. Early modifications of these engines used oil that could be released into the environment with the 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 air injection into the receiver in the process of closing and opening of the piston in the cylinder, while the lapping is performed "dry". In order for the pistons to work without oil, they had to be modified. So, the cylinders themselves began to be made from a more resistant material - cast iron, and a special cooler was designed to reduce the temperature that rises when the parts of the apparatus rub against each other.

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

What to look for when choosing a compressor:

1. Piston group type. As previously mentioned, oil units can release oil particles into the atmosphere, which then enter the human lungs. To prevent air pollution, carbon filters are installed on such devices. To keep the air clean, they need to be periodically cleaned 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 disadvantages are leveled by a clean air mixture without impurities, safe for human health.
2. Noise level during the operation of the installation. The maximum allowable value is 80 dB.Devices manufactured using modern technologies give an average of 60-65 dB. If such parameters still do not suit the buyer, you can purchase a sound-absorbing cabinet that will reduce the 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 volume of consumption of each of them must be summed up to select the device with the required power. The approximate flow rate of the turbine is 30-40 l / min, the saliva ejector is 20-50 l / min, the water-air pistol is 11-20 l / min. Since no compressor head is capable of supplying the 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 an air mixture until the required pressure is reached. It is from it that 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 replenishes stocks. When choosing a receiver, the first thing you should pay attention to should be the container's coating material. To prevent rusting, the tank should either be made of stainless steel or be enameled on the inside. For small medical institutions, a receiver will be sufficient, which is completely filled with a compressor in 3-4 minutes.
5. The presence of a filter. Almost all modern compressor plants are equipped with multi-layer filters with a function of retaining dust and oil particles. The better the filter, the cleaner the indoor atmosphere will be. This element is mandatory in oil devices, which are characterized by the emission of fine liquid particles.
6. Dehumidifier availability. 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 harder and longer the hardening process. Dehumidifiers are used in compressor units to reduce humidity.

You need to choose a compressor unit based on the scope of use. A small dental office will need only one compressor and a receiver. For a dentistry department, which includes two or more workplaces, it is irrational to buy several units. The best option would be to install one powerful apparatus, which, by wiring, will supply the air mixture to all workplaces. The unit must include multiple 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 disadvantages, 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 for Extending the Life of Dental Compressors

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

Weekly you need:

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

Once a month you need:

• audit all connections for tightness;
• check that the working pressure corresponds to that stated in the instruction manual;
• 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 incoming filter (if the contamination is not strong, clean it; if the dirt is not removed, the cleaning cartridge must be replaced);
• after 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 while the device is in operation and evaluate the result of the action by the noise of the released air).

Calling a specialist is required in the following cases:

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

Mercury HK-1EW-30

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

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

The unit has 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 pressure in the tank. The air filter is installed at the inlet only. The legs of the device are equipped with soft shock absorbers that prevent it from moving across the floor.

During the operation of the compressor, moisture forms, which is collected in a special container. For the catchment system to work effectively, it must be cleaned at least once a month. It is recommended to clean the air filter with the same frequency, which eventually becomes clogged with dust, which leads to increased energy consumption and poor filtration. It is recommended to carry out maintenance only by qualified personnel: once every 2-3 months, you need to wipe the dust from all elements of the device, check the reliability of the connections, check the presence of a contact in the grounding cable. The device can only be used indoors at temperatures from 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 laying in some margin. The higher the capacity of a 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, first of all, on technical characteristics (such as performance, noise level, number of serviced installations, etc.), and only then on cost.

We recommend choosing appliances with oil-free technology. In combination with a good filtration system (at least a filter is required at the inlet to the tank), 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 obstacle for the high-quality hardening of the filling material.

If the dental office is small, the size of the compressor should also be taken into account. 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 the compressor to be removed to another room, if necessary.

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