A furniture factory in Binh Duong was running two piston compressors that had reached the point where maintenance cost more than the machines were worth. Air quality at the spray booth was also marginal, with visible oil carry-over reaching the guns.
What was installed
A single 11 kW screw compressor with a receiver and a refrigerated dryer, sized to the spray booth and the pneumatic tools on the assembly lines. The old piston units were kept as emergency backup only.
Result
Pressure at the booth is steady through the shift instead of dipping when a second gun starts, and the oil carry-over that was reaching the finish has gone. Maintenance is now one service a year rather than a continuing repair list.
