Oil Type Air Compressor Rating
Oil-type air compressors are becoming more and more popular in everyday life. They outperform oil-free counterparts in terms of continuous operation duration, increased resource and efficiency.
Oil-type compressors are installations, the cooling principle of which is based on the circulation of a lubricating fluid (crankcase oil) in a closed circuit. In addition to the function of heat removal, oil in these units is used to lubricate rubbing surfaces, which include bearing assemblies and a crank mechanism (a pair of crankshaft-connecting rod of the piston) by spraying and whipping into a fine suspension.
Best Belt Driven Oil Compressors
Metabo Basic 250-24 W
The smallest and, concurrently, the noisiest representative of the rating, whose power is 1.5 kW. Metabo Basic 250-24 W is a typical model of a reciprocating air compressor for a garage or for a home, the capacity of which (200 liters per minute) is enough for any utility (or design) business. The inlet pressure at the outlet of the system can be up to eight bar, while the crankshaft speed with one piston does not exceed the threshold of 2850 rpm.
From a safety point of view, the Metabo Basic 250-24 W is the clear leader in the category, since it only contains a control valve, a safety relief valve, and an overheating protection that responds well to minor exceeding the permissible temperature values. Adds color to the "home" model of the compressor and the fact that its weight is only 27 kg, which greatly facilitates any transportation manipulations.
Remeza SB4 / S-100.LB30A
A high-quality model of an oil compressor with an electric motor from a Belarusian manufacturer, the cost of which adequately corresponds to the declared performance characteristics and additional functionality. Power indicators of Remeza СБ4 / С-100.LB30A remain at the level of the opponents in terms of rating (2.2 kW), however, the efficiency in terms of performance significantly "outstrips" some of them. Dispensing up to 420 liters of air per minute, this unit can be used in a small production or service enterprise, since its characteristics will be very redundant for a garage.
Judging by the reviews of experts, the main plus of the model, given its overall dimensions, is that the working circuit is equipped with a sensitive overheating protection system that responds to the minimum output of indicators beyond the relevant limit. A slight disappointment on the part of users was the weight parameter (88 kg), which complicates the transportation of the compressor unit and the receiver, but in fact this is the only nuance among the advantages of Remeza SB4 / S-100.LB30A.
Denzel PC 2 / 100-370
An extremely interesting representative of the oil belt compressor segment, the advantages of which are the low price and the presence of important regulating / protective elements. Despite not the highest percentage of efficiency, Denzel PC 2 / 100-370 has sufficient potential for comfortable work with pneumatic devices in a garage workshop or a small enterprise with the required main channel for compressed air supply.
The capacity of this unit is 370 liters per minute, which for a power of 2.2 kW is, if not the largest, but a very high indicator. Much more interesting are the advantages of Denzel PC 2 / 100-370, reflected in user reviews. In addition to the presence of pressure regulation and an overheating protection relay, this model turns out to be lighter than its own kind (only 69 kilograms). Together with good durability, such a selection of useful supplements is a significant factor for taking a leading position.
Fubag VCF / 100 CM3
The 2.2 kW electric oil compressor is the benchmark for quality and durability among belt driven models. Minute capacity of Fubag VCF / 100 CM3 at its peak can be 440 liters, and this is the best result in the list of nominees.
Consumers call the indirect advantages of this compressor the presence of an accurate (which is important) pressure gauge, a 100-liter receiver and a two-stage process of compressing air to a pressure of 10 bar. A small nuance is the noise level, which can reach 79 dB, but with proper arrangement of the working space, this harmful factor can be leveled. In general, Fubag VCF / 100 CM3 is the most durable compressor in this segment, and in terms of price-quality combination leaves the vast majority of direct competitors out of business.
Best Direct Drive Oil Lubricated Compressors
PATRIOT Euro 24-240
An electrically driven Chinese compressor, the main feature of which is the abnormally low weight of the structure. This is explained, first of all, by the desire of manufacturers to save on materials of manufacture, in connection with which the total massiveness of the elements was 17 kilograms. However, this nuance did not affect the performance of PATRIOT Euro 24-240 in any way: at 1.5 kW of power, the compressor capacity is almost 240 liters of air every minute, with the possibility of a reserve of 10% (24 liters) in the installed receiver.
User reviews are interpreted as mostly complementary, with rare indications of disadvantages due to the low price. There are not so many of those here, but they are all tied to the fragility of plastic parts. One of the "weak" points of the structure is a rough plastic casing, a careless blow on which (even a light one) can lead to a break. There were also complaints about valve taps, but this is, rather, the fate of that minimum percentage of defective goods (up to 4%), rather than a "sore" of the entire series.
Fubag FС 230/24 CM2
German compressor "kid", the performance of which is close to that of Quattro Elementi KM 50-380. Great for the garage and home workshop, even despite the loud (even by the standards of enterprises) noise emission equal to 80 dB. The most important feature of the Fubag FС 230/24 CM2 is as follows: consuming only 1.5 kW of energy, the compressor produces 230 liters of compressed air every minute (at a pressure of eight bar), some of which is used to replenish the 24-liter receiver.
As an additional incentive to purchase, the manufacturers equipped the Fubag FС 230/24 CM2 with a control valve to correct the required pressure, as well as protection against overheating, which is especially important in the later stages of compressor operation. Considering all of the above, as well as the acquisition cost, we can talk about the next act of domination of Fubag over its competitors. At least in the 1.5 kW compressor niche.
Quattro Elementi KM 50-380
A rather expensive oil compressor made by an Italian company, the volume of air supply at the outlet of which, with a power of 2.2 kW, reaches 290 liters per minute. The development of Quattro Elementi KM 50-380 was carried out taking into account the requirements of small industries that widely use pneumatic equipment. Behind the impressive design of this product, including the pipes and connecting wires, there is a very high percentage of the working resource, which will require very tough operating methods. This fact was repeatedly voiced and noted by experts who recommended the compressor for purchase from a number of similar ones.
As for consumer opinion, in their reviews, users put in the first place not the technical capabilities of Quattro Elementi KM 50-380, but the visual side. Well, as a method of initial engagement, the "brutal" black art trick worked great, and we have no doubt that the technical side is also capable of supporting this stimulating impulse.
VORTEX KMP-300/50
A small direct drive air compressor that achieves an impressive 300 liters per minute. This result is achieved thanks to the 2 kW of nominal power built into the electric motor of a fairly compact unit. There is a 50-liter receiver, the volume of which is quite enough for long-term work with pneumatic equipment in a small workshop or service enterprise.
From the point of view of users, a pleasant addition to the capabilities of VORTEX KMP-300/50 has become a pressure regulator, as well as an overheating protection circuit, introduced into the design to prevent emergencies. In a similar way, the owners of the model also speak about its good transport data, since 20 kg of weight is easy to carry with the help of two wheels. Given a low price and a very good selection of technical parameters, the domestic development fits perfectly into the rating of the best.
