Preventive maintenance The benefit of preventive maintenance is without question. An unforeseen machinery breakdown is accompanied by a production shutdown, a loss of income and may even force a delivery limitation. Correct maintenance, as well as properly planned and precise implementation of necessary repair, saves time and money. How do you carry out maintenance? Detailed information about the maintenance of your pneumatic tool can be found in the instruction manual. If you no longer have the manual in your possession then you can request either a printed or pdf-file version from us at...

The quality of the compressed air is a critical factor for the The use of an air filter is just as important. Dirty air can block the lifespan of an air tool. The integration of a water separator as vanes and damage the motor. well as a central air dryer protects not only the air system, but also the air tool from corrosion. In regard to air quality according to ISO 8573-1, we recommend: *) for tools that are operated without lubrication, it is sufficient to use a filter with 8pm. To attain the proper air quality, we recommend the DEPRAG A regular inspection of the air filter for impurities...

Lubricated or non-lubricated operation of tools? DEPRAG pneumatic screwdrivers, air motors and vane operated tools can be operated without lubricant. This causes a reduction in power of approx. 15%. The optimum life-span and performance of an air vane motor is achieved by 1-2 drops of oil in 1 m³ air consumption. A larger amount of oil does not bring any advantages, it just increases the use of oil and burden on the environment. The air consumption data for your machine can be found in the relevant brochure. Advantages of oiled compressed air: - Lubrication prevents the direct contact and...

Maintenance intervals An example of how to determine the required maintenance interval of a screwdriver spindle follows. The screwdriver spindle is used under the following operational conditions: Using the formula (see below), a maintenance interval every 2 million cycles is necessary, which equals about 1100 operating hours. – The air quality fulfils the demanded requirement. – The screwdriver spindle is operated oil-free. – The screwdriver spindle is operated at its medium power level. – The cycle time for one assembly is two seconds. The maintenance interval changes when operating...

How to repair an air vane motor Components of the vane motor Gap between rotor and bearing cover 6 Rotor cylinder Rotor Bearing cover Gap between rotor and rotor cylinder Bearing cover Rotor cylinder Bearing cover Vanes Air inlet channel Exhaust channel After the dismantling of the vane motor and thorough cleaning of all parts, the following parts must be evaluated closely regarding further usability: – Rotor Cylinder: The rotor cylinder must be exchanged if deep grooves or indentations are found on the surface of the rotor cylinder, which are signs of polluted compressed air! The rotor...

How to repair an air vane motor Components of the planetary gear DEPRAG air tools mainly use planetary gear drives, to achieve a high torque capability. During repair as well as maintenance, the following parts must be tested for wear and if necessary replaced: – Ball Bearings: Ball bearings can only be re-installed if they rotate perfectly. Usually, ball bearings are replaced after long-term use, in order to guarantee their functionality. – Gear Support: The encased bearing pins in the gear supports must be surface tested for grooves. If the bearing pins show grooves or unevenness, then...
