How to run Yong Heng Compressor - Part 2, Tips, Tricks and Traps

In Part 1 we setup our Yong Heng, now it's time to learn the secrets to successfully running our compressor and charging our tanks or PCP. In Part 3 we will learn important safety considerations when working with high pressure gear including compressor safety.

[@robgee7788]

Thank you for this video series. I am setting up the same system you have here and you brought up a bunch of things that I didn't consider. This helped me quite a lot. Many thanks!

[@CaliforniaTravelVideos]

Agreed LOL (after the Covid era shutting down paintballing for over a year, I find it helpful to refresh my recollection too)

[@jonathanstaley3883]

Very cool comprehensive video! Thanks a million!

[@22lr_plinking]

I’ve watched a lot of videos on yong hengs and you touched on what others missed. Excellent job and very much appreciated thank u👍👍👍

[@CaliforniaTravelVideos]

Thank you Vinny and it's great that we all have one another to learn from and share. I must say that once I started watching all the YH videos, forum posts, etc, from time to time it had me wondering what was possible, true, necessary, best practices, practical and affordable. And I hope I came across as balancing most of these factors rather than promoting my personal view or setup and lessons learned... which admittedly vary from others setups, priorities and working conditions/environments. Good luck Vinny and I hope you enjoy your new gear.

With out a doubt this is the best Yong Heng video I have seen to date. I have used mine 3 times now and I wonder why they make them with the auto shut off if they want you to bleed the air before shutting down. I will stand there and watch mine and not use the auto shut off, I have it set at around 4500 psi in case I should get side tracked. Which is not likely, I will only fill my tank to about 4200/4300 psi . I don't shoot as much as I would like to, once I check to see if I'm still on it is hunting time. I will say this, at my age (67) my Yong Heng is by far better that the Hill pump I purchased LOL. I love my 25 cal. Benjamin Marauder Gen 2 it is super accurate , but man is it an air hog 16 shots per( fill 3000psi) at 821 fps average. My FX Bobcat MKll 84 to 90 shots per (fill 3200 psi) at 873 fps and it to is amazingly accurate. I just hope this air compressor will last for ever, I will do my part and take care of it and service it regularly. Again great video.

[@StrokerNormH1]

Great videos (both part one and two)! Concise & awesome presentation! I just received my YH today & am sure that I will be able to set up my Yong Heng safely & properly tomorrow night.

[@themc69]

Great video. I watched many videos for the this compressor. You added many things that other missed. I now feel I can use mine safely. The first run will be today. Thank you.

[@moonlitnite49]

Awesome, it's nice for everyone to share their experiences and "lessons learned," or as the tongue-in-cheek badge on my cap says... Bad Decisions Make Good Stories! I'm sure you''ll have and exciting time as you leave the launchpad as we all have done - welcome to Compressor World, Yong Heng style...

[@kurt9399]

I see a few points of contention from my view . The main observations are no Safety Glasses and bleeding back wards thought the filter system seems to be a bad idea. Distilled water and a small amount automotive antifreeze to reduce the effect corrosion.

[@PseudoSane]

Super helpful, thanks!

[@CaliforniaTravelVideos]

Many thanks and good luck with your new addition.

[@Eric_McBrearty]

Very informative, Thanks for such a thorough explanation of your setup.

[@TerryThomas812]

much help appreciated. thank you

[@CaliforniaTravelVideos]

Good show Pete - glad to hear you are also happy with your Yong Heng. Agreed, initially it does seem odd to have an auto shutoff when the compressor seems to last longer by first bleeding the line. But wait a moment, let's step back and think about this a bit more... YH itself does not make specific warranties about fitness for use in a given situation or environment and I think we will all agree after looking at the two-stage piston, crankshaft and cooling system, it is not designed and engineered for rough use, or long run sessions either. And because it provides so much pressure volume in such a short time, I would guess the tolerances on the two-stage piston are being stressed more than competing products that cost 5-20 times as much. So I agree with other YH careful users who take extra steps to avoid taking extra changes by stressing the compressor more than necessary. Of course, some folks are fine ordering parts for broken pistons, etc. and the cost of parts is very affordable and replacement time is only an hour or two once you know what you are doing. But for me and others, we treat our YH very carefully and want it to last. And I'm with you, charging to 4300 is fine. For your Benjamin Marauder Gen 2, I've read others who pump by hand say you should get 16 shots from 3000 to 2000 PSI for their 25 cal (bottom limit) but everyone has their own idea on the best pressure range so it sounds like you do not have a leak. And as you know, if you are shooting longer than 40 yards distance from the target, the pressure will start affecting your accuracy. Happy trails!

[@METEORPaintball]

Great informative video!

[@barzdun]

excellent video!

[@yellowsnow6541]

im subbing. so much good information

[@letitride54]

Great video,

[@ProjectAnubisUSA]

Heads-up: Don’t forget the more filter media, check valves, etc. you have to push the air through the harder it is on the small compressor causing it to heat up faster due to air restriction. Try breathing through a straw the same principle applies. Question: what fittings do you have (sizes) so we can find them easy please.

[@CaliforniaTravelVideos]

Regarding your question about replacement filter ordering: You can search eBay for "I ordered 2 packages of 50 on eBay 50PCS Pump Filter For Electric High Pressure YONG HENG 30MPa Air Compressor" The packaging on my bag shows SKU722300-14338973 PCK (Made in China), also shows numbers 1204-0-11475 and E2-H-02-22. FYI - the Item price was $17.18 (for 100), Item number 222860027664 from the eBay contact. Good luck!

[@ProjectAnubisUSA]

Is that a Christmas 🎄 tree stand with pvc you mounted too? 🤔🤫🤐

[@CaliforniaTravelVideos]

@@ProjectAnubisUSA Nailed it! (any port in the storm - lol)

[@jackagain8346]

When I'm done I also blow out the water lines so there's no water left in the piston head jackets.

[@michael-tichaelnistler4107]

Terrific idea - many thanks for sharing :)

[@robwoodall7162]

Great utube vid

[@feidaikind]

Good morning, sir, First of all, thank you for this video, which is very instructive. I wanted to buy this little compressor, but seeing all this system you've added, it scares me a little bit... I don't know what to think about all this. If I embark on this adventure, without any knowledge, on all these filters added, I'm afraid I won't buy it and do the right thing...

[@CaliforniaTravelVideos]

Greetings Stephane. Sorry if I made setting up the Yong Heng compressor seem too complicated. And while it's built-in cloth fiber "cigarette filter" seems a bit inadequate for my preference, even adding an inline charcoal filter would be helpful to keep water vapor from getting into your gear. The main points are to ensure you have good oil in the motor, try to keep the water cool and prevent the YH from getting too hot. Good luck!

[@bobrussell4049]

Please recommend a one-way valve with foster fittings and source as you discussed.

[@headcrackersilentsniper9111]

Amazon..type in one way check valve

[@JMSynthetics]

If you have a one way valve on your scuba tank why did you wait to open the valve? wouldnt it auto normalize?

[@CaliforniaTravelVideos]

Good point JM (actually the one-way I've added is on the filter, no one-way on the tank). Since most watching the video will not have added the additional one-way check valve, I thought it best to show this technique. The idea is to ensure we don't needlessly cause too much pressure from the tank or filters to hit the delicate Yong Heng compressor piston and values. So I'll always error on the side of caution, equalizing pressure on both sides before opening valves. Thanks again for pointing out the benefit of a one-way valve and let's not forget we need a pressure relief value on the OTHER SIDE in order to be able to disconnect the hose and filters! In my case I have a pressure release valve on the filter.

[@JMSynthetics]

California Travel Videos thank you for taking the time to reply, i just got one of these hca yong heng pumps myself to refill paintball tanks so i have been watching videos for setup and use and yours was very detailed but wonder about the valve, do you have links to the dual filter setup you used?

[@ivasmith8184]

Thanks, great video. Did you mention the oil you use? Did I miss it? Did I see a royal purple bottle? That is what I bought. Brian Smith

[@moonlitnite49]

For sure, I use Royal Purple Synfilm 100 - WTG!

[@CaliforniaTravelVideos]

@Matt E Agreed, and we should definitely be mindful to use our eyes and NOSES! If your oil starts to smell bad, STOP NOW and replace that oil!!! And of course, look in the sight glass from time to time and notice when the color begins to darken. And of course, try to avoid prolonged run times with the temperature running 60+C. While this temperature would not be a problem with a different compressor with a design meant for continuous long time operation, such is not the situation with the Yong Heng. Our secondary high pressure piston is quite fragile and the true temperature at that point is 10+ degrees higher than the digital reading on the first stage piston we are viewing. Further, the water cooling tubes are quite small and cannot transfer the heat away that quickly. So we should try not to run the compressor for more than 20-30 minutes before letting it cool down for a brief rest period (releasing pressure from the bleed valve as we shutoff the valve to the air tank (if you don't have a one-way valve).

[@40motomike]

Link to the connections you used? valves etc?

[@ja001son]

I have this pump and mine stalls and shuts off at 1000psi with both bleeders closed, suggestions? Edit, it's set to shut off at 3000

[@hiseminencetheholymacdiarmada]

I run a desiccant filter on the intake. I have a half gallon mason jar with color changing desiccant. I want the air to be dry before it ever comes into the compressor.

[@moonlitnite49]

Assuming you live in an area with moderate to high humidity, that sounds like an excellent idea to reduce moisture before it gets into the YH. And as I found out, just be sure you have a sufficient amount of airflow input to your compressor inlet.

[@hiseminencetheholymacdiarmada]

Yes, I live in the south and it’s very humid here. I also have the TUXING air dryer on the output, I run it with half molecular sieve and half activated charcoal. For my job, I use an SCBA and I fill my own tanks. The air is completely odorless and completely dry. These little machines are awesome!

[@headcrackersilentsniper9111]

I thought distilled water was the recommended method? On the forum all the guys recommended using distilled water to avoid corrosion, but you say no.? Please explain

[@robwoodall7162]

We’re did you get water pump

[@CaliforniaTravelVideos]

While you won't be able to push 400+ Gallons Per Minute with a better pump, something like this one will certainly push muck more water through your YH is certainly helpful: www.amazon.com/dp/B01LHC8UX8/

[@unballisticr.i.pdadloveand7055]

I can’t believe no one is using 3 sponges either side of the tube and fill the tube with Rice cheap and works fantastic

[@CaliforniaTravelVideos]

Good point - makes one wonder why Yong Heng didn't think of that!

[@truthspeaker2062]

It sounds different with others yong heng's compressor

[@CaliforniaTravelVideos]

Perhaps that's because I am using a high quality $360 Countryman E6 microphone connected to a Sennheiser wireless transceiver - this helps prevent loud compressor noise to overwhelm hearing me when speaking. Many folks use the microphone on the camera which make the compressor sound different.

[@cornfields-crosshairs4182]

@@CaliforniaTravelVideos I love your neediness......what DON'T you think of?!?! Hahaha!!

[@TheGregWallace]

why don't you stir your water to make it cooler?

[@CaliforniaTravelVideos]

Since the ice is in bags and isolated from the water, stirring the water is not applicable. If cooler water temperatures were required, adding more ice bags would be helpful... or even running an external air fan on the piston head.

[@TheGregWallace]

@@CaliforniaTravelVideos why would you have the ice in a bag?

[@moonlitnite49]

Sorry if that wasn't clear in the video: 1. Yong Heng compressors quickly get hot and have minimal cooling, considering the design (high pressure output, low cost) 2. Adding ice to the intake water supply help to cool the YH 3. To provide extra cooling and water less likely to create corrosion of the YH valves, PURIFIED water (not distilled) with coolant additives are used instead of tap water that contains minerals and other contaminants. 4. Separating the ice from the water (using a bag) allows the water to be cooled without coming in contact with the 5 gallon water supply 5. When not in use, the 5 gallon bucket with the mixture of Purified water and coolants is covered to avoid evaporation and contaminants from getting in the water supply. FYI - a case of Nestle Pure Life Purified Water 16.9 oz 12 each bottles costs $2.48 on Amazon, which is 1.5 gallons so buy 2 cases for $4.96 (3 gallons leaves room for some coolant and a bag or bags of replaceable ice). And 2 bottles of Royal Purple Ice Coolant costs $12.00

[@TheGregWallace]

@@moonlitnite49 freeze the distilled water into ice cubes.

[@CaliforniaTravelVideos]

Hi Greg. Yes, if I had a really big freezer, I could simply freeze some of the PURIFIED water (distilled is not recommended) and simply add it back with the room temperature water in the 5 gallon bucket. But if I'm running the compressor for maybe 15-20 minutes, I'd go through 2 one gallon ziplock bags worth of water, which I'd have to make a day or two ahead of time and find precious space in the icebox. Since my freezer compartment always has plenty of premade ice, I've found it easier to just dump some in a ziplock freezer bag and float it in the 5 gallon tub until it melts. But for those with a large freezer, I really like your idea.

[@kenjackson4177]

Sorry but I have to correct you on something, Oil and Oxygen don’t mix,,,, oil and high pressure Air are common everyday in motors and pumps. Some may think I’m being picky with language, but if we are going to be careful and precise, we need to be correct.

[@CaliforniaTravelVideos]

Yikes, agreed and sorry if I gave the impression mixing oil and high pressure was acceptable - NOT!!! In fact even water vapors can be harmful to high pressure metal assemblies that can corrode, rust and eventually rot away!

[@TheDWZemke]

Lol we need to be precise and accurate. Nothing that being exact and wrong.... they are two different concepts... sorry Ken..

[@kenjackson4177]

TheDWZemke So are you commenting on my grammar or chemistry? At least point out my mistake if you are going to comment, but the Chemistry clearly points to Oxygen and petro carbons being a bad mix.

[@seantyree8443]

1 bar is 14.5038 i was told

[@binness]

@sean tyree and you are correct, the man doing the video is wrong, but he states it with such conviction that people believe him, also the picture of the head that he shows with a kind of propeller is also wrong, the Yong Heng does not have that, one wonders how much reliance should be placed on the rest of his information ?

[@binness]

People are praising you, but if they searched out the information that you have on here, they would see that some of it is totally wrong, I won't thumb you down for it, however people should be aware that you are wrong, I will mention but 2 things, firstly you got the pressure conversion number wrong, secondly the second stage head that you show with the propeller thing is not true, or at least not in the legitimate Yong Heng

[@CaliforniaTravelVideos]

Thanks for your feedback - always great to hear from others. Please feel free to share your pressure conversion chart information and links to your photos of the two-stage YH compression heads.
