Reduce the water vapor in the compressed air of the two methods can also help reduce the oil content of compressed air.
不同类型的绝缘材料会从空气中吸收不同量的水分，所以最好选择水蒸气不容易在其上形成连续膜的绝缘材料。
Different types of insulators will absorb varying amounts of water from the air, so it's best to choose an insulator on which water vapor doesn't readily form a continuous film.
