Drive

The method of transferring rotation from the motor shaft to the working mechanism of the compressor.

— Straight. In direct drive compressors, the operating mechanism shaft is aligned directly with the motor shaft — therefore, such models are also called coaxial. Their main advantage is the low cost due to the simplicity of the design, as well as the small dimensions of the compressor unit. However, this simplicity does not extend to repairs: it is likely that even with a small malfunction, you will have to disassemble most of the device. In addition, this option is characterized by a high level of noise, and the speed of rotation of the shaft is quite high, which greatly wears out the working mechanism. It is very difficult to create a high-performance compressor based on a direct drive, because design features adversely affect cooling efficiency. Therefore, such models usually belong to entry-level devices with low performance.

Belt. The operation of this drive is based on the use of two pulleys (one on the motor shaft, the other on the shaft of the working mechanism) connected by a drive belt. It is more bulky, somewhat more complex in design and more expensive than a straight line, but outperforms it in a number of other indicators. First of all, this is performance: separately located engine and working mechanism is much easier to cool, which allows you to create compressors of almost...any capacity without the risk of overheating. In addition, due to the difference in the diameter of the pulleys, the speed of rotation of the shaft of the working mechanism is lower than that of the engine, which further reduces heating and has a positive effect on the resource. Belt-driven compressors are easy to repair and maintain (due to the ability to access the engine and mechanism separately), and their noise level is low.

Input performance

The amount of air that the compressor is able to process per unit of time; usually stated in liters per minute. Performance, along with pressure (see below), is one of the most important parameters: it is it that primarily determines how compatible the compressor will be with one or another pneumatic tool.

It is worth choosing a model according to this indicator in such a way that it can be guaranteed to “pull out” all the tools that can be connected at the same time. Air consumption is usually directly indicated in the characteristics of each tool, and it is quite simple to calculate the total requirement. However, due to the design features, the compressor must have a certain performance margin; the specific value of this stock depends on a number of nuances.

The main point is that some companies indicate for their units the performance at the outlet (how much air is supplied to the tool), while others indicate at the inlet (how much air the compressor sucks in). Since no compressor is perfect, part of the air is inevitably lost during the compression process, so the amount of air at the outlet will always be less than at the inlet. Accordingly, if the output performance is indicated in the characteristics, a margin of 10-20% is recommended, and if the input is 35-40%.

There are also more complex techniques that allow you to more accurately derive the required performance depending on the characteristics of specific tools; they can be found in...special sources.
