When using pneumatic tools, there are various parameters that must be observed in order to achieve the best possible result.
Our operating instructions contain technical information, e.g. details of working pressure, hose diameter, etc. These details must be observed as they have a significant influence on the performance of the pneumatic tool.
These specifications must be observed as they have a significant influence on the performance of the pneumatic tool.
Working pressure
- Reducing the recommended working pressure by 1 bar leads to a reduction in performance of up to 25 %.
- A hose diameter that is too small or a hose length that is too long will reduce the air flow rate and thus the performance of the product.
- A working pressure higher than specified promotes earlier wear of the tool.
Compressor
- A pneumatic air tool is operated with compressed air. A compressor is required to generate the compressed air. The compressor must be selected so that it can continuously generate the required amount of compressed air.
- In the operating instructions for our pneumatic tools, we specify how much air is required to achieve the required performance. Depending on the model, our impact wrenches require between 70 and 283 litres of compressed air per minute at a working pressure of around 6.3 bar.
- The specifications on the compressor are often given as "unpressurised".
This means that if "150 litres per minute" is indicated on a compressor, this is the amount of compressed air that the compressor produces without pressure in the boiler. - As the required working pressure increases, the amount of air produced decreases. A large workshop compressor is required to generate and store 150 litres of compressed air per minute at a working pressure of 6.3 bar. An "ordinary household compressor" with a 25-litre compressed air tank generates an average of 200 litres of compressed air per minute. The motor (usually approx. 1.5 kW / 2 hp) works against a pressure of at least 6.3 bar in the compressed air tank. This often leaves an effective potential of only one tenth, i.e. around 15 litres per minute.
- It is therefore advisable to compare the data between the compressor and the tool to be used.
Compressed air hose
- The hose diameter and length are decisive for the full performance of the compressed air tools.
The inner diameter of the hose should not be less than 10 mm to ensure the necessary air flow rate. The shorter the hose from the compressor to the device, the lower the friction loss and the full pressure generated by the compressor is available to the device. Please be sure to observe the recommended inner diameter of the hose specified in the operating instructions. - Tip: be sure to take a look at our pressure loss calculator
Maintenance and care
- Clean, dry air and daily oiling guarantee the lengthy service life of your air tools
- The longevity of the pneumatic tool is crucially dependent on maintenance.
- Observe the information in the operating instructions regarding storage and maintenance.
Pneumatic tools
The performance of an impact wrench operated on compressed air is influenced by various parameters. A key factor is the compressed-air system to which the impact wrench is connected. As compressed-air systems vary from user to user, it is not possible to specify reliable torque values that apply to all such systems.
For professional workshop use, you will need a large workshop compressor with a tank capacity of at least 200 litres
Smaller compressors are usually unable to supply the impact wrench with a sufficient supply of air over the long term. This means you have to keep taking breaks whilst working so that the compressor can refill the air tank.
The working pressure is always measured directly on the device whilst air is flowing through it. Why not have a look at our pressure loss calculator too?
The air connection nipples we supply usually have sealant applied to the thread; furthermore, most air connection nipples have tapered threads. It is therefore usually not possible to screw them all the way down to the bottom of the thread. If the thread alone does not provide a sufficient seal, you can help by using a little Teflon tape, for example.
Air quality is specified in ISO 8573-1. According to this standard, the air should be as dry as possible (no condensation), oiled (for corrosion protection and lubrication) and free from foreign particles. After the compressor, your system should therefore at least include a water separator, a fine filter and a lubricator.
