Need compressed air? Then you are welcome to us: TOP-5 compressors

Metabo Basic 250-24 W OF is an oil–free compressor for domestic use. This design allows the unit to work even on an inclined surface (it does not need a perfectly horizontal position, as for oil). This model supplies clean air without any impurities, which is very necessary in the operation of a dental unit, or in the production of some food and pharmaceuticals. However, the lack of oil affects the rapid wear of parts.

There is a safety valve on the left side of the housing, which can be opened forcibly and reduce the overpressure in the receiver in case of failure of automation. The pressure regulator will allow you to set the amount of atmospheres that you need at the outlet for the operation of the pneumatic tool. It produces a compressor up to 8 bar, which is quite enough to connect a spray gun, a purge or a sandblasting gun. At the bottom there is a tap that allows you to simultaneously bleed air and drain water from the tank.

The Metabo compressor has large rubberized wheels and a front handle located at an angle, which allow you to conveniently and quickly roll the device to the right place. By the way, its weight is only 24 kg. The receiver is designed for 24 liters – this is a small volume, and with prolonged operation it will often turn on / off (for air refueling). A capacity of 220 L/min is quite enough for most household pneumatic tools, with the exception of demolition hammers and impact wrenches.

The Korean oil compressor from Hyundai has an enlarged piston of 46 mm, which provides an air supply of 250 L/min. Hyundai HY 2024 is equipped with two outlet tubes for connecting two pneumatic tools at the same time. The performance is enough for two purge guns or two tyre pumping tools. The receiver here is small by 24 liters, so in automatic mode the compressor will often turn on / off.

The cylinder block is made of cast iron with large ribs, which in combination with aluminium heads cools the engine well. At the bottom there is a tap for draining condensate accumulated during operation in the receiver. With the help of a rotary switch, you can set the right pressure to work with a certain type of pneumatic tool.

The connection of the pneumatic tool takes place in a matter of seconds thanks to quick-release connectors. As in Metabo BASIC 250-24 W OF 24 L Price from 8 358 up to 11 662 ₴, the Korean compressor has a convenient transport handle and two large wheels. It is worth noting that for an 8 bar oil compressor, the model is quite inexpensive.

STURM AC9323 is a German oil compressor, perfect for household needs at home and for working in small car repair shops. It produces 350 liters of compressed air per minute, which is enough for a spray gun, a grinder or an impact wrench. However, the pressure force here is 7 bar, which is relatively small, given the dimensions and the two-cylinder system, and it will definitely not be enough for an industrial demolition hammer. You can connect two pneumatic tools at the same time — the pressure is regulated at one outlet, but not at the other (7 bar is supplied at once).

The STURM AC9323 model uses a belt drive, which greatly increases the service life of the compressor head. Due to the difference in pulleys, the speed of the head is much lower than the speed of the engine. In addition, this design gives good access to each working element for repair or replacement. However, the absence of a casing on the engine can lead to the fact that it will be heavily polluted in a dusty room. The condensate drain tap will allow you to get rid of unnecessary liquid.

The design is equipped with two relays: temperature and regulating pressure. The first turns off the unit when overheating, protecting the engine from breakage, and the second turns on / off the compressor when the desired pressure is reached /dropped. A nice addition are the two air filters that come with the compressor. The front handle is very comfortable and large, but the plastic wheels are a little "pumped up", as they knock hard during transportation and are less durable than rubber ones. It is also worth noting that the weight of the STURM AC9323 is quite big — as much as 62 kg.

The Italian oil compressor Abac A29B/50 CM3 has a nominal pressure of 10 bar and is capable of delivering up to 320 liters/min of compressed air, which is enough to work with such a serious tool as an impact wrench and a bump. A gearbox with a regulator is installed on the receiver, which allows you to set the pressure required for a specific pneumatic tool. Additionally, there is a slot at the end of the receiver for connecting the tool without the possibility of adjusting the pressure (10 bar is supplied directly). The unit gains maximum pressure in just 3 minutes and 5 seconds (when turned on).

Like the compressor Sturm AC9323 50 L 230 V , the Abac A29B/50 CM3 model is equipped with a belt drive that increases the length of the "life" of the compressor head. The motor itself and the rotating pulleys are closed on one side with a casing that protects the working elements from dust and moisture, and also reduces noise. On top of the engine there is a starting capacitor and a "reset" button, which allows restarting the unit in case of an automation failure. The model is equipped with a faucet for draining excess fluid and thermal protection of the engine.

Under the air filter there is a "window" to display the oil level, and a refueling indicator. There is a valve for forced pressure relief on the body, but there is no ring on it, so it will take a lot of effort to tighten it. The cylinder body is made of cast iron with five thick ribs. They provide good cooling of the piston during the injection of air into the receiver. Separately, it is worth noting a convenient rubberized handle and two rubber legs that bend under the tank during transportation. The model costs a lot, but it can work several thousand hours before serious repairs.

FIAC AB 100-360 is a really serious unit for small auto repair shops and service stations. Two cylinders pump 10 bar in 4 minutes and 7 seconds, and this is taking into account a large receiver per 100 liters. And with a capacity of 360 L/min, you will not experience a shortage of compressed air even when working with several pneumatic tools, for example, pistols for pumping tyres or spray guns. To ensure such performance, the model is equipped with a powerful 2.2 kW three-phase motor. Please note that it can only work from a 400 V network, so it is worth finding another model for owners of single-phase networks.

The FIAC AB 100-360 compressor is equipped with quick-release connectors that allow you to connect a pneumatic tool with a minimum of time. On the body of the unit there is a bolt with a washer for connecting the standard grounding (indicated by the corresponding icon), which can be installed in any industrial premises. Nearby there is a drainage valve for draining condensate, which accumulates in the receiver from time to time. The piston system and the engine have an "open" design without a protective casing, which is why dust can settle on them during operation.

Long-term operation of the cylinders is provided by lubrication in the form of oil. Thanks to the viewing window, you can control its level and refuel if necessary. The cylinders are cooled by a cast-iron body with thick ribs. Thanks to the belt drive, the speed of the compressor head pulley is significantly reduced, which increases its service life and reduces the vibration of the unit. Three wheels are responsible for transportation (the front one has a rotary system). However, the compressor itself weighs 75 kg, which creates a problem when lifting to floors or transferring to another room. The cost of the compressor is quite high, but the service life is estimated for tens of years.
