Orient Series Piston Compressors
|
Overview
XP dual-bearing series piston air compressors are referred to as air compressors hereinafter. Its matched power is 3~7.5kw, rated air displacement is 0.3~1.0 m3/min and rated discharge pressure is 0.7~1.4 MPa.
XP dual-bearing series, improved on the basis of the original XP series, adopts the seriation design, employs the double supporting structure in place of the traditional crankshafts cantilever supporting structure of micro-air compressors, and shows its superiority in stability, reliability, longevity, etc.. The rest technical performance parameters are the same as the original XP series.
The series air compressors can be widely used in pneumatic work clamps, tire aerations, spray painting, blowing process and pneumatic jet components. |
