Oil compressors: a brief educational program
Depending on how the lubrication system is organized in the compressor, oil and oil-free devices are distinguished. Oil-free models do not use lubricant directly in the air transfer process, although they also need it. But in oil compressors, special compressor oil is used without fail. The air and oil passages in this type of compressor are not isolated from each other, as in oil-free models, but intersect. Therefore, compressor oil not only lubricates the mechanism and provides cooling of parts, but is also present in the forced air.
Due to the design features, oil-filled compressors are characterized by high power, performance and reliability. They have a very very large MTBF resource. In addition, oil compressors can work continuously for a very long time. All this makes them the most suitable choice for professional and industrial applications. In addition, it is oil compressors that are used in painting, since their oil-free counterparts have a lot of hydrogen in the air discharged from which the paint bubbles.
The advantages of oil-lubricated compressors are evident. At the same time, these devices are quite expensive and bulky. They require great attention and careful maintenance: add oil to the level and check the condition of the parts after each session of using such a device. In addition, oil compressors are not very suitable for powering pneumatic tools: oil particles in the forced air do not have a very good effect on the durability and reliability of the tool. Because of this, oil compressors are not used as actively in everyday life as in construction and industry.
Oil-lubricated compressors are manufactured all over the world. Historically, the most technically advanced and reliable compressor units are produced in Germany. Under the brands Metabo and Fubag: two models from these manufacturers have made it to our top 5 oil compressors. True, the products of these companies are quite expensive, so the domestic brands Vikhr, Caliber and Wester successfully compete with European ones, offering good quality at reasonable prices. Let's take a closer look at the best oil-lubricated compressors.
Top 5 oil compressors
1. Metabo Basic 250-50 W
Oil-type electric piston compressor from a renowned German manufacturer. The power of the device is 1500 watts. This is enough to create a pressure of 8 atmospheres with an inlet capacity of 200 and an outlet capacity of 110 liters per minute. The maximum number of revolutions per minute is 2850. Horizontal receiver with a volume of 50 liters. Pressure regulation and overheating protection are provided. There is a safety valve and a pressure gauge. Noisy (81 decibels) and heavy (32 kilograms), but it works out its price tag of 12,000 rubles in full.

2. Fubag DC 320/24 CM2.5
Another oil compressor with a piston electric motor from a large German brand. This time, however, cheaper - for 10,000 rubles. But in terms of functionality, this device even surpasses the previous model. Its power is 1800 watts, pressure is 8 atmospheres, and its output capacity is as much as 320 liters per minute at a maximum of 2850 rpm. The volume of the horizontal receiver is 24 liters. A pressure gauge, wheels and a carrying handle are provided. With all the richness of functionality, this is a fairly compact unit that weighs only 25.5 kilograms.

3. CALIBER KMK-2100 / 50U
Coaxial oil compressor with a single-cylinder piston engine, which clearly shows that domestic brands are also not bastard. 2100 watts of power, 8 bar maximum pressure, 270 liters of compressed air per minute. The horizontal receiver has a solid volume of 50 liters. The design includes a pressure gauge, as well as wheels and a carrying handle. A very decent model that costs every penny out of its 8500 rubles. It will look great in a garage or even in a small paint shop: for most tasks, this compressor has enough capabilities with a margin.

CALIBER KMK-2100 / 50U
4. Wester W 006-075 OLC
A relatively inexpensive and compact piston electric oil-type compressor with a price of 7,000 rubles. A modest 750 watts of power is enough to maintain a pressure of 8 atmospheres with a capacity of 126 liters per minute at 2850 maximum rpm. The volume of the horizontal receiver is only 6 liters, so it fills up instantly. Provides pressure adjustment, safety valve, pressure gauge and oil level indicator. The unit weighs only 16.4 kilograms, so it is quite convenient to move it - especially since there is a carrying handle here, albeit without wheels. A good model for personal use or even a small car service.
Price: ₽ 6 899
Wester W 006-075 OLC
5. VORTEX KMP-210/10
Small piston compressor with oil type electric motor. The unit costs only 6,000 rubles, but it can do a lot. The power here is as much as 1600 watts, the maximum pressure is 8 atmospheres, and the inlet capacity is 210 liters per minute at 2850 rpm. The volume of the receiver is 10 liters. There are all the necessary functions like pressure regulation and overheating protection. The device is equipped with a pressure gauge and a carrying handle. At home, in the country house or in the garage, he will definitely find a place for himself, but for professional use it, perhaps, will not be enough.

Popular questions
Are oil-type compressors suitable for painting cars?
It is oil compressors that are best suited for painting cars: oil-free compressors have a lot of hydrogen in the air, so the paint can bubble. Oil models do not have this problem.
conclusions
Oil-immersed compressors are powerful and reliable devices that are used in professional and industrial environments. They require lubrication and proper care, but the many advantages outweigh these disadvantages. We hope our material has helped you with the choice of an oil compressor just for your needs.
