Budget (YH Like) Compressor Tips Compilation and experiences

Jump to latest Follow Reply
Even using a good synthetic compressor oil and keeping your tampon filter changed you can still have the smell of oil in your tank or rifle. If you want to eliminate the smell you would need to run a carbon filter in line to remove the odor. We are not breathing this air, it's just for our guns and the smell won't hurt them but oil could so keep up with your tampon filter.

For sure, just change oil to a RP and yes, it stink less, but still smells ... WARNING: Do not use this air to breath! ;)

As I said in another post, you need a gold filter and desiccant beads .. There are posts on this hack.. Basic gist is to cut the tampon into 1 1/2 -two inch pieces sections for the inlet and outlet of the filter .. Get one of the clear report covers from a local store and cut to length to fit between inlet and outlet threads and cut so when you roll it up it fits in the filter like a sleeve.. Place a tampon piece on one end insert the sleeve you made and fill so the other tampon piece will fit.. .. I setup the filter vertically on a tripod with my tank that I am filling above it.. I have a fill nipple on the inlet so pressure will be trapped in the filter and the fill hose to the tank.. That way you do not have to close the tank vale when your waiting for the compressor to cool down on a long run as stated in a post before this in this thread.. Remember if you are filling your gun do not use the fill nipple ,just a normal nipple as you will have no way to bleed the pressure off the line..

I have seriously been considering getting one of these!! My local dive shop is super sympathetic to the airgun community but it would be nice to have the ability to fill my tanks at a minutes notice. Not to mention if something happens and they are closed!! Thank you for the helpful tips!!

Hi AGN,I always worry about the water flow, so I was wondering if it would hurt anything if I put some food coloring in the water so I can see [ just by looking at the hoses ] if it's circulating? I ran it once when I thought the pump was on and of course it was'nt. Fortunately it's breaker kicked it off and it still works.

Suggestion: Drill a small hole in the top of the bucket so the return hose goes there and never touch the water, that way you alway see

I've used a plastic tool box for a long time with my YH. Holds enough ice for a large tank top off from 3000 to 4500 and the handle makes it easy to carry when done. Much as noted for the buckets, I drilled a hole just below the closed lid and ran the lines through those holes. The return goes through just a couple of inches so it stays above water level. Just a glance verifies water flow.

I'm using a plastic ammo box from Harbor Freight for a cooling reservoir. It holds 2 gallons with about 3 inches of airspace above the fluid level so more could be added if I wanted to. It's got a rubber sealed lid so it can be moved without spilling any fluid. I mounted 3 hose barbs through the lid. one for outlet one for return and one for vent / temp probe. With this setup I haven't seen the pump temperature go above 58*C yet. Although the biggest thing it's filled so far is topping off a 3 liter bottle which took less than 10 minutes. Fluid temp rose about 16*F. I must add that the pump is out in my unheated camper and ambient temps have been fairly low 40* to 60*F so it could certainly run hotter when the weather warms up into the 90s. Right now I'm using Dexcool at 50 / 50 mix for cooling since as I said the camper is unheated when not in use and it's been pretty cold since I got it. If this is not satisfactory when warmer I have small transmission cooler / radiator I'm going to mount in front of the pump's cooling fan and see if that keeps temps under control.

On another older thread I saw concern for the temps of the stainless high pressure lines. It was posited that the final line was getting over 200*F. I can't find anything on the pump registering higher than 128*F and that includes low pressure cylinder and final high pressure SS line. And yes 126*F is very uncomfortable to touch. But not at all too hot for a 300 BAR pump IMHO.

Yesterday when I was ready to pump my tanks, it happen something that I like to share. I have the auto stop version.

I made the setup as usual, then I connect the power supply cord, first to the wall then to the pump, and the pump turn on immediately, . I realize that the power button was on, since I forgot to turn it off (since is auto shut off can happen), so no worries I turn the pump off. That took like 3 seconds.

I did wait like 20 seconds and turn the pump on, only to realize that it won't start...I repeat the process several times (switching on and off) and just a buzz from the pump, but not working...try it like 2 minutes and nothing, so I decide to take the cover out. When I took the power cable it was almost melt hot, never happend that before...so I took it out, remove the cap, everything was normal, my first thought was...damn, need a new pump. (more than a Year using it).

So I reconnect everything in the right order with the pump off, turn it on and it was working like nothing happend. I fill my tank as usual....

what could happen? maybe an electrician can explain me? was weird...

When I used my YH ( genuine version ) the other day, the sound was a bit abnormal. It seems that something is not running smoothly or it is struggling against some load but the symptom disappeared after about half a minute and it worked fine afterwards. I also noticed that the pressure wouldn't build up at all in the first 20 seconds or so and it suddenly jumped up before steadily going to 4500 psi in the usual manner. I have the feeling that it will quit working soon. Can anyone share your thoughts on what might have going wrong ? Can it be the check valve ?

Sadly it was not just an oring, piston rip 😔
