Air End Servicing include the following

Standard bearing replacement due to high running hours as recommended by bearing manufacturer.

Bearings replacement (we use bearings the best world bearings manufacturers). Damaged bearings from heat, damaged bearings from poor lubricant quality.

Replace all Seals, O-Rings and Gaskets.

Rotor surface recovery (if necessary).

Housing geometry recovery (if necessary).

Reset from face and rear face clearance to air end manufacturers specifications.

Air end shaft seal kit replacement.

Overhauled Air Ends will reduce load on the motor and extend electric motor life and save energy

The optimal gap adjustment and rotor alignment, gaps regulation:

Gap and rotor alignment adjustment is released with using special tool, due to the highest efficiency of the air end and long lifetime of the unit is providing. The gaps adjustment are in certain ranges, which provides high efficiency.

If during compressor operation the gaps (for example, end gaps) will be adjust less than minimum value of the range, rotors heat, metal expands and it is a reason the rotor and housing contact. As rotation speed is high, shortly metal weld.

Then the screw unit can be just utilize. If the gaps are higher than maximum value of the range, efficiency decreases because of air-oil mixture leaks, as well as parameters of the cooling element and rotor lubricant are changed, that prevent to decrease the air end lifetime.
