故需要注入的油很少，需要的油气分离器，过滤芯负荷也很轻，输出的压缩空气含油量自然极低。

Therefore, the oil needs to be injected is very little, the needed load of oil and gas separator, filter core is also very light, the output of oil content of compressed air is also natural low.

So it needs to the injection of oil, the oil and gas separator rarely need and filtering load is also very light, the output of the compressed air natural very low oil content.
