Since the plastering machine distributes the material on the wall, compressed air is needed for its operation. This is necessary to be able to distribute the material evenly on the surface.
Usually, this requires a compressor that is able to compress the air and thus build up compressed air.
In principle, cleaning machines are usually sold without a compressor, since a compressor is usually already available, especially in the factory. Thus, there may already be a device that can be reused for another purpose.
Obi and Bauhaus, for example, offer the possibility of renting a compressor.
For private users, however, it makes little sense to buy an expensive compressor, as the price for this can easily run into several hundred euros. Some companies therefore offer the possibility of renting compressors for a certain period of time.
For the private user, this is often the cheaper way, unless the compressor is to be used for a longer period of time and/or for other purposes.
