Pneumo riveters are specialized pneumatic and pneumohydraulic riveting tools that can work with the largest rivet diameters, as well as install heavy-duty pin connections. Such pneumatic tools require connection to compressed air supply systems supplied by a compressor, and it is also desirable to use a compressed air preparation unit to remove foreign moisture and dust. But these are the most powerful and productive of all riveters. The riveting process itself takes place in a matter of seconds and requires almost no effort from the operator. This allows the uninterrupted use of such pneumatic models on large production lines and for the assembly of massive metal structures.
