1.4 General description of the machinery
The machinery described in this manual is motor compressor D425T4F.
The motor compressor is a piece of machinery with the capacity of generating a given quantity of compressed
air in l/m by using a diesel engine as primary energy.
The pneumatic energy finds applications in different fields of use, where "pneumatic" operation tools,
accessories and equipment are utilized. For instance: demolition hammers, drilling hammers, vibrators, drilling
machines, rammers, coating machines, etc.
Each of these tools/-accessories has its own consumption of compressed air, expressed in litters per minute.
The optimum coupling between the compressor and the tool is achieved when the compressed air consumption
does not exceed 85% of the air generated by the compressor (furthermore, it must be taken into consideration
that the quantity of compressed air required by the tool shall increase in time, proportionally to the wear of the
tool itself).
The correct compressor-tool coupling ratio allows the machinery operating in optimum conditions, as
appropriate to ensure long life-span at the highest performance.
An oversized tool - besides creating unfavourable conditions for the appropriate operation of the machinery -
shall not develop full performance, since it cannot resort to the required quantity of compressed air.
This machinery has been designed to work at ambient temperature ranging from -10°C/14°F and +40°C/125°F.
