The compressed air used in the spraying workshop was normal at first, but after several months of operation, the compressed air contained moisture and grease, which seriously affected the product quality. It's no problem to use the equipment like you do now at first, but it's normal for oil-water mixture to appear after several months of use. First, there is no professional degreasing equipment in this configuration, which will lead to oil pollution of gas equipment in the later stage. Secondly, because the system is equipped with an adsorption dryer, the adsorbent in the adsorption dryer has the ability to adsorb oil in compressed air at the initial stage of operation, but it has no regeneration ability. After running for a period of time, the oil absorption effect of the adsorbent reaches saturation. When the adsorbent is saturated with oil, an oil film will form on the surface of the adsorbent, which will hinder the absorbent's ability to absorb water, which is also commonly known as adsorbent "oil poisoning". To sum up, there will be no oil and no water in the initial use. After the equipment runs for a period of time, the adsorbent is "oil poisoned" and cannot absorb water and oil, resulting in oil-water pollution after degreasing. It is suggested that you add a professional degreasing device between the freeze dryer and the adsorption dryer, which can completely remove grease and protect the adsorbent in the adsorption dryer.

I hope the above can help you.
