Compressor comparison: Here are the most significant differences
Compressors differ in many ways. For example, you can find models with or without a tank, with oil lubrication or oil-free, with cordless battery power or connected to the mains with a cable, and finally our Silent models, known as whisper-quiet compressors. To make it easier for you to find out which compressor suits your needs, we'll explain the exact differences.
Loud or quiet: Working with whisper-quiet compressors
Compressors produce a lot of pressure – and are not exactly quiet. Especially when working for a long time, for example with compressed air tools, it is recommended to wear hearing protection, because conventional compressed air compressors reach volumes of up to 97 dB (LwA). Human hearing can be damaged from as low as 85 dB. Depending on which accessories are used, the volume will of course increase even more. For example, renovation work with the compressed air chisel hammer can be very noisy. Hearing protection is therefore essential for this work.
Turn it down with the Einhell whisper-quiet compressors. You can spot these models as they include "Silent" in their name. Thanks to their special mode of operation, the Silent compressors achieve noticeably lower noise levels and are significantly quieter than other models, at noise levels of up to 57 dB (LpA). For a better comparison: While a normal compressor with up to 75 dB (LpA) can get as loud as a washing machine during the spin cycle, the quiet compressors only reach the volume of your TV at normal room volume, at around 55 dB (LpA).
The Einhell Silent compressors are whisper-quiet compressors that operate around 40 dB quieter than conventional models.
Different drive types for various locations
With or without power connection: You need the right compressor for where you want to work. Each drive type offers its own advantages.
- Cordless compressors: The Einhell cordless compressors can be used without a power connection and cable chaos. Combined with a Power X-Change battery, they can be used wherever they are needed. Because the battery-powered models are therefore perfectly suited for mobile use, they tend to be rather compact and equipped with a carrying handle.
- Hybrid compressor: The Einhell hybrid compressor PRESSITO offers the best of both worlds and combines the advantages of cordless battery power and mains operation: The small, compact compressor is easy to carry and can be operated either with a mains cable connection or with a Power X-Change battery. Thanks to the accessories on adapters and hoses for low-pressure and high-pressure pumping, which are stored in a side compartment and in the housing, the small compressor is also perfect as a mobile companion.
- Corded compressors: Continuous performance without interruptions is no problem with corded models. If there is a power connection where your compressor is used, you can of course use the conventional compressor with a power cable. These models are particularly suitable for time-consuming, continuous work. They reliably supply the necessary energy, without worrying about battery charge levels.
Oil-free vs. oil-lubricated models
In addition, the various compressor models can be divided into oil-free and oil-lubricated models. The difference is quite simple to explain: In oil-lubricated compressors, the moving parts in the compressor are lubricated so that it does not overheat, even with very powerful applications. Oil-lubricated air compressors therefore have a long service life, are well suited for continuous operation and are extremely powerful. They are recommended for the use of mechanical compressed air tools such as impact wrenches and chisel hammers.
Oil-free compressors have their own advantages: They are usually lighter and more manageable than oil-lubricated models. In addition, apart from draining the condensate, they do not require any additional servicing. This also eliminates the need to dispose of waste oil, which makes the oil-free compressed air compressors cleaner and more environmentally friendly. Due to the lack of oil, these devices also have no problem operating at cold temperatures, as they reliably start up at any outside temperature. Due to the lack of lubrication, oil-free compressors are better suited for less powerful tasks; for example, for pure compressed air work with accessories such as tyre fillers, blow guns, sandblasting guns or paint spray guns. If mechanical compressed air tools are still to be used, it is advisable to connect a lubricator between the compressor and the tool.
Oil-lubricated compressors are better suited for powerful applications, while oil-free models are lighter and more environmentally friendly.
Air reserves: With or without a tank?
In the Einhell range you will also find compressors with and without tank. Working with compressed air tools usually requires more pressure and air volume than the compressor can deliver. The pressure boiler provides a solution for this, as the necessary air is stored there. So, if you want to tackle intensive, endurance tasks with your compressor, you should use a model with a boiler. In the Einhell range you will find models with a tank volume of up to 90 litres. If, on the other hand, you need a handy compressor you can use to inflate car tyres, balls or air mattresses, for example, a model without a tank (inflator) is also suitable.
If you are faced with intensive tasks that require time and effort, a compressor with a tank is recommended.
