Mattei Air Compressors

Rotary Vane vs. Rotary Screw Air Compressors

Mattei’s rotary vane technology is simple and features a single off-set rotor which is supported by two (2) white metal Babbitt bushings (like the connecting rods in your engine) and spins at but 1,800 rpm or less. Blades/vanes slide in and out of the rotor to form compression pockets. Zero-wear Meehanite™ treating process prevents wear to the stator wall or the cast iron blades that ride on a thin film of lubricant. Backed by a 10 Year Warranty, the rotor stator unit (RSU) is exceptionally durable and efficient, and it is not uncommon to get over 100,000 hours of service life out of our airends (RSU) without a rebuild.

In comparison, rotary screw air compressors are complex and sensitive to precise tolerances and are composed of two parallel rotors with external helical profiles (screws) which enables the two rotors to engage, one into the other. The two rotors are fitted with four (4) roller bearings and two (2) thrust bearings and placed inside a stator made from two cylinders which intersect longitudinally and in which the rotors turn with a critical minimum clearance at speeds between 3,000 and 8,000 rpm via belts and sheaves or gears. Oil is used to seal, cool and compress the air which results in blow-hole losses and declining efficiencies outside of the ideal speed range. Engineered bearing life is 50,000 hours, but installed airend life tends to be between 35,000 and 40,000 hours between major overhauls.
