A wide range of applications are oil-free type compressors. These devices can be found in the food and pharmaceutical industries, in mechanical engineering and in everyday life. Since the device works without oil, the output is high-quality compressed air. This is the main advantage of oil-free compressors. Today, the Russian market has a wide range of devices from different manufacturers. Our experts will help determine the main selection criteria.

Compressor Selection Criteria

Design Features. Oil-free compressors differ from each other in their design.

  1. Spiral models are a simple device where two spirals play the main violin. One of them is in a static position, and the other is constantly rotating. This is how air is injected.
  2. The screw compressor consists of two chambers. In one of them, air is drawn in from the atmosphere. In another chamber, two screws rotate towards each other, forcing air.
  3. The piston device resembles the operation of an internal combustion engine. Only the piston is driven by the torque that is transmitted through the crankshaft from the electric motor.

Power and performance. The key features of an oil-free compressor are electric motor power and unit performance.

  1. For working with airbrushes or cleaning computer equipment, small models with a power of 0.3-1 kW are suitable, producing up to 180 liters of compressed air per minute.
  2. If you want to work with pneumatic tools or paint work, it is preferable to take a more powerful (1.1-1.5 kW) and productive (200-250 l / min) unit.

Receiver. Depending on the type of work performed, the size of the receiver is also selected. The smaller the volume of the tank, the faster the compressed air leaves and the compressor often has to turn on. But a large receiver makes the device heavy and dimensional, which is inconvenient for transportation or home use. Therefore, with a small flow rate of compressed air, compressors with a receiver up to 10 liters are suitable, but for volumetric work it is better to take a model with a tank of 20-50 liters.

Convenience of movement. When the compressor often has to be moved from place to place or transported, the user pays attention to such moments as weight and overall dimensions.

  1. Lightweight models (up to 20 kg) are usually equipped with legs and a carrying handle.
  2. Heavier compressors are equipped with wheels, which simplifies moving around the workshop or garage.

Equipment. Compressors and a wealth of equipment are distinguished.

  1. Novice masters should take a closer look at the devices, with which there is an air hose, a spray gun, purge and pump guns, all kinds of nozzles.
  2. Professionals already have the necessary set of additional accessories. Therefore, it is preferable for them to buy only the compressor itself.

We have selected 7 of the best oil-free type air compressors in our review. Buying them in stores in Russia is not difficult. When allocating seats, the editorial board of Ecdfburma magazine based on the conclusions of experts, not forgetting the feedback from domestic consumers.

Kraton AC-300-50-OFS

Rating: 4.8

The Kraton AC-300-50-OFS compressor stands out against competitors for its high performance. The model has a coaxial drive, which allows for a low pressure (2 kW) to create a pressure of 8 bar. The productivity of the device at the inlet reaches 300 l / min, compressed air from two compressors accumulates in the receiver with a volume of 50 l. The reverse side of high technical parameters is a large weight (40 kg), which limits the movement of the device. Experts gave the silver models of our review.

Russian users note such advantages of the compressor as a 3-year warranty, quiet operation, and rapid pressure build-up. By cons, they include one outlet for pneumatic tools, unreliable tightening of the fastening connections.

Advantages

  • high performance;
  • large receiver;
  • silent work;
  • 3 year warranty.

Disadvantages

  • heavy weight;
  • limp build quality.

Fubag HOUSE MASTER KIT

Rating: 4.7

The optimal ratio of productivity (180 l / min at the outlet), weight (18.2 kg) and price has a Fubag HOUSE MASTER KIT compressor. Experts consider the model an excellent option for working in the country or in the garage. The model is equipped with an economical electric motor (1.1 kW) and a 24-liter receiver. But most of all, the device attracts potential buyers with its rich configuration. Together with the compressor, the manufacturer supplies a spray gun, a hose, a blower nozzle and a tire inflation gun.

The third line in our review is explained by the difficulties with setting up the device. At the first start, the motor refuses to turn off after the maximum pressure has been set, only the emergency valve is activated. The problem is solved by turning the adjusting screw counterclockwise.

Advantages

  • rich equipment;
  • light weight;
  • good performance;
  • affordable price.

Disadvantages

  • adjustment required.

ABAC Start O20P

Rating: 4.6

Of the advantages, high air quality, anticorrosive coating of the receiver, and economy are noted. The single-cylinder model has a direct drive, which allows the maximum use of a small motor power (1.5 kW). The weakness of the Italian compressor is a small receiver (6 l).

Domestic users are still restrained about the device, they are not satisfied with the high price and a small supply of compressed air. There are no complaints about the build quality, anti-corrosion coating and performance.

Advantages

  • high quality;
  • lightness and compactness;
  • good performance;
