Compressed air oil removal
Thread Content
The air compressors in our factory are oil-based compressors, and due to their age, the compressed air contains a relatively high level of oil. The company’s products have been upgraded, and the manufacturing process now requires that there be no oil droplets in the compressed air used to spray onto the lenses. A cold dryer, a desiccant dryer, and precision filters have already been installed; only an activated carbon filter is still missing. I’m wondering if there are any other methods to remove oil, in addition to installing this filter Thank you, expert
Air compressors come in various types; if oil can be seen spraying onto the lens at the compressor outlet, it is likely that this equipment requires a thorough inspection and repair. It’s best to send a video to see what the cause is; this is indeed a good topic. As for the oil removal methods you use, they cannot remove oil fundamentally, and they also cause a great deal of waste. There are two governance methods that might solve your problem. First, the defects in the equipment need to be rectified and repaired; second, a water scrubber should be installed to remove oil mist from the water. I’m not aware of the purpose of your compressed air; if you need moisture-free dry gas, a silica gel adsorber will also be required. . . . . Add the appropriate equipment as needed. Additionally, it is necessary to conduct calculations to determine whether equipment upgrades or the purchase of suitable new equipment is more cost-effective.
Here, I mainly use compressed air to clean the lenses, and there are high requirements for this compressed air – not only regarding its dew point but also its oil content
Just switch to an oil-free screw air compressor or a centrifugal air compressor; adding a dryer will do as well
Hehe, said so easily – just blow on the lens. If these lenses are to be used as camera lenses, they need to have quite high precision. It would be best to send a video so people can take a look.
Today, the technicians from the manufacturer came to install it. What surprised me was that for the last precision filter, they installed it with the inlet and outlet in the wrong order; they claimed it still worked, but didn’t explain why. Yet it indeed functioned properly. I don’t know what the principle is

You use gas on the laser cutting machine, right?
No, it’s used on optical glass
There is also a specialized compressed air degreasing device, namely the Bausch degreaser, which has become quite popular recently. This device seems to be completely different from precision filters; it’s worth taking a look at.
