喷砂使用的空气由压缩机出来需要经过冷凝器与滤清器过滤。每次使用前需用白纸进行检测(方法:压缩空气对白纸吹1分钟,距离100~150mm,观察是否有水分或油污)。


 

The air used for sandblasting is filtered by condenser and filter when it comes out of compressor. White paper shall be used for detection before each use.

The method is as follows: blow white paper with compressed air for 1 minute, with a distance of 100-150 mm, and observe whether there is water or oil stain.
