    Long story short, I couldn’t get good groups with my Impact and I decided to investigate. I found oil at the bottle and and the reg wasn’t working properly. Opened up the reg and found oil. Traced it back to my compressor. DO NOT BUY A YONG HENG COMPRESSOR!!!!!!!

    That's why its important you need to use the tampon filter and desiccant filter. I would think all air compressors are similar as they all use oil and create moisture.

    This is concerning! I am sorry for your trouble Helimech. I have a Tuxing two cylinder that has me wondering about it. I can smell that exhaust it puts out filling from my gun when I shoot. I did just change oil and the lower tampon was oily some, there was some moisture present in the desiccant on the low end but all the upper end along with the charcoal and upper tampon were dry.

    Guess I best do some homework today.

    I'm not trying to sound snotty so please don't take this the wrong way but proper filtration would have prevented this problem. I run a coalescing filter along with desiccant and molecular sieve and my guns are dry and clean after years of use.

    I did use the tampon and desiccant filters.

    Can i ask what you used for oil? I haven't noticed oil with my guns although the tampons do get dirty. BTW i use SAE 30 nondetergent.

    Sorry my computers old and didn't want to play the video so i didn't see the filters you use.

    How often do you change the tampons?

    Shooting buddy of mine changes both of his tampon filters at every fill and has no issues…

    Your aiguns are not ruined, It's going to take time to clean but I don't see where it would cost money. Hundreds of people use these compressors for every one that has problems.

    I like to run the big filter in the vertically. I use an Alpha filter and don't get any oil… just water gets blown out the bottom of the filter after filling my 74cf tank every time.

    Sorry to hear about the damage. I've always suspected oil contamination with the Yong Heng compressors. All pistons and cylinders wear. The Yong Heng is no exception to the rule and I doubt any filter is bullet proof.

    I refuse to use any compressor that incorporates petroleum products. I can handle  a little water or white lithium but oil and high pressure air are a bad combination. Not only will compressed oil mix with water under high pressure but it creates carbon deposits that can ignite and explode in HPA tanks or air cylinders.

    Out of the thousands of people using them, how many times has this happened?

    Don't really know but it only takes one and if your that one in a million your day just got real bad. I hear a lot about the cylinders on the Yong Heng compressors exploding. Wonder if that could be due to carbon deposits or simply mechanical failure. At any rate I wouldn't want to be in the same room when it happens.

    There is a chance of being stuck by a meteor but I'm not wearing a helmet every time I got outside. I'm sure your chance of being injured in a car accident is thousands of times higher but you still ride in cars. Everything we do is a calculated risk… we either lock ourselves away or live our lives.

    Filtering compressed air is 2 part, oil/particulates and moisture. Always filter the oil out first, then the moisture. The farther away you can mount the filters the better, as that will give the moisture/oil time to cool/condense to droplets and be much easier to remove than vapor. Run you compressor in short bursts to avoid getting high outlet temps that won't allow moisture to condense. Using a cooling water bath before/or submerge the desiccant filter in an ice water bath might help. Also paying attention to keeping the temp of the compressor coolant water very low might also help. Just some thoughts from someone very familiar with compressors/gases/filters.

    Filtration temperature, among other factors, has an significant impact on the filtering process. Filter efficiency is also impacted by the oil concentration in the compressed air as well as the amount of free water. Don't over fill your compressor with oil, not even a little. Efficiency specs in the filter specifications always applies to a specific air temperature, usually 70°.

    Good point but even if the carbon deposits don't ignite they will destroy your equipment because an explosion is the only way you'll ever remove them.

    I don't see it happening with a proper filter. How many millions of scuba tanks have been filled by a compressor using oil? Our government sold the law that says 25% synthetic additives can be called 100% synthetic oil. The risk is extremely low when exercising due diligence.

    Dont buy a ford or a dodge or a chevy guys ive heard some have broken down in the past.  Stern warning.

    Heres a piece of cotton at my final output from my YH.  Zero moisture or oil residue signs,  ive had my gun completely apart with zero signs of moisture inside.

    Check filter media and change as needed, simple.
