Oil-free compressors are widely used. These devices can be found in the food and pharmaceutical industries, in mechanical engineering and in everyday life. As the device operates without oil, it produces high quality compressed air. This is the main advantage of oil-free compressors. Today the Russian market offers a wide range of devices from different manufacturers. Our experts will help you determine the main selection criteria.

Compressor selection criteria

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

1. The spiral models are a simple device where two spirals play the main violin. One of them is in a static position, while the other is constantly rotating. This is how air is pumped.
2. The screw compressor consists of two chambers. One of them sucks in air from the atmosphere. In the other 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 characteristics of an oil-free compressor are the power of the electric motor and the capacity of the unit.

1. For work 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 need to work with pneumatic tools or carry out painting work, then it is preferable to take a more powerful (1.1-1.5 kW) and efficient (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 more often the compressor has to be turned on. But a large receiver makes the device heavy and bulky, which is inconvenient for transportation or home use. Therefore, with a low consumption of compressed air, compressors with a receiver up to 10 liters are suitable, and for large-scale works it is better to take a model with a tank of 20-50 liters.

Convenience of movement. When the compressor is frequently moved from place to place or transported, the user pays attention to issues such as weight and dimensions.

1. Lightweight models (up to 20 kg) are usually equipped with legs and a carrying handle.
2. Heavier compressors are equipped with castors, making it easier to move around the workshop or garage.

Equipment. Compressors differ in the richness of the equipment.

1. Novice craftsmen should take a closer look at the devices that come with an air hose, a paint spray gun, blowing and pumping guns, and all kinds of nozzles.
2. Professionals already have the necessary set of additional accessories. Therefore, for them, it seems preferable to buy only the compressor itself.

We've handpicked the top 7 best oil-free air compressors to review. It will not be difficult to buy them in stores in Russia. When allocating seats, the editorial board of the magazine took the conclusions of experts as a basis, not forgetting about the responses of domestic consumers.

Craton AC-300-50-OFS

Rating: 4.8

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

Russian users note the compressor's advantages such as a 3-year warranty, quiet operation, and fast pressure build-up. On the downside, they include one outlet for a pneumatic tool, unreliable tightening of fasteners.

Advantages

• high performance;
• large receiver;
• quiet work;
• 3-year warranty.

disadvantages

• heavy weight;
• the build quality is lame.

Fubag HOUSE MASTER KIT

Rating: 4.7

The Fubag HOUSE MASTER KIT compressor has an optimal ratio of productivity (180 l / min at the outlet), weight (18.2 kg) and price. 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 set. Together with the compressor, the manufacturer supplies a spray gun, a hose, a blow off nozzle and a tire inflation gun.

The third line in our review is explained by the difficulties in setting up the device. At the first start, the motor refuses to turn off after reaching the maximum pressure, only the emergency valve is triggered. The problem is solved by turning the adjusting bolt counterclockwise.

Advantages

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

disadvantages

• adjustment required.

ABAC Start O20P

Rating: 4.6

The Italian ABAC Start O20P compressor is distinguished by its ease of use. Experts classify the model as an industrial class for its high productivity (230 l / min), the ability to adjust the pressure and low weight (14 kg). Among the advantages are high air quality, anti-corrosion coating of the receiver, and efficiency. The single-cylinder model has a direct drive, which makes it possible to make the most of the low motor power (1.5 kW). The weak point of the Italian compressor is the small receiver (6 l).

Domestic users are still restrained in their attitude to the device, they are not satisfied with the high price and 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;

The unit is perfect for working with airbrushes and pneumatic staplers. A comfortable wide handle is available for carrying the compact device. The compressor can be operated both vertically and horizontally. The amount of incoming air and pressure can be adjusted.

Domestic consumers like compactness, lightness, affordable price and ease of use. But the noise level does not suit users, as well as the real maximum pressure level (6.9 bar).

Advantages

• profitability;
• lightness and compactness;

However, experts consider the main advantages of the model to be compactness, lightness and good quality. The compressor falls into the 6th place in our review because of the small receiver.

Many users find the 2 liter supply of compressed air insufficient. Within 8 s, the receiver is emptied, so the compressor has to work constantly.

Advantages

• compactness and lightness;
• rich equipment;
• affordable price;
• high-quality assembly.
