Compressed air, in fact, is used as a means of transmitting energy to drive operating machines (rock drills and tools, pumps, hoists, motors, etc.) or in cases where ventilation is difficult (for example in tunnels) or, again, used by all earth moving machines to carry out excavation, loading, transport and levelling of geological materials and debris.
Mattei rotary vane compressors, the result of an advanced and constantly evolving design, offer a valid solution to these needs: the low rotation speed of the air end and the high volumetric efficiency determine energy savings of more than 15% compared to other rotary compressors. Moreover, rotary vane compressors do not use ball bearings or thrust bearings, but use oil-lubricated brass bearings that do not wear out over time.
The technological innovation of the vanes allows the compressor to reach 100,000 operating hours while maintaining constant performance and limiting maintenance operations to oil changes at scheduled intervals, air filter cleaning or replacement and radiator cleaning. The greatest efficiency and construction technology allow Mattei compressors to offer the lowest Life Cycle Cost on the market.
In addition, in quarries and construction sites, earth moving machines work on uneven or steeply sloping ground, which puts the proper functioning of the systems to the test and makes it essential to adopt air compressors capable of ensuring construction characteristics that prevent damage, while maintaining the high performance and safety levels required. The configuration of the lubrication and oil injection system of a Mattei compressor is designed in such a way as not to compromise its operation even at high inclinations. This construction feature allows the compressor to maintain high operating performance even in particularly critical conditions.
