Best way to fill up tanks at home

Answer would likely be a shoebox compressor, basically a booster that takes 120psi from a standard shop compressor and boosts it to up to 4500 psi.

my only concern would be how much power it sucks up doing so so you may be trading off in paying more in your electric bill. Maybe some other members can chime in to see how true this is.

other option would be to call around to some air supply places and see how much a nitrogen tank lease would run you. Usually a $100/yr lease for the tanks and $180 for fill ups. Downside is the tank is huge (weighs almost 400 lbs) and alot of places don’t deliver. You would also need to provide your own fittings which would run around $200-400 depending on what you wanted to do.
 
There is cheap and then there is easy. From experience the easiest is the nitrogen tank. If you don’t count dealing with the tank itself. Once it is in place nothing to it. About $500 to start. Couple hundred a year on the average for gas. It’s what I’ve gone to after having an expensive compressor fail.

This is probably the most expensive part of air gunnng. If you can conveniently get your tank filled stick with it. 

Cheap? Probably the Chinese compressors . I have no idea how easy they are to use. I’m not convinced that they produce clean and dry air or that their life span makes them the way to go but it seems they are pretty popular 

there is a ton of information on this forum about this. Read it and pick your own poison 
 
The shoebox is more of a booster as it requires an additional shop compressor that will produce 100 psi and the shoebox will boost that up to 4500 psi. But it's very slow. About 10 hours to fill a tank from 0 to 4500 psi if I'm not mistaken. Cheapest way is to go with the yong heng. It's only $230 with no tax and free shipping on ebay. People have use it with good success. Go look up yong heng on youtube and you will see many reviews from folks who used it for years and it's still working fine for them. 
 
If I were to purchase a yong hang compressor what else would I need to fill my tanks

Oil of course. I suggest getting royal purple 100 iso oil. But other oils for compressor will do fine too. It comes with all fittings to fit any pcp that has a quick disconnect. Last, you can get a gold filter, not needed but does help filter out dirty, oil, and water to get the driest air. Just search gold filter on ebay. They run about $70 to 80. Go watch youtube videos on the compressor before you jump into it to know what you are doing. 

This guy does a great review on his yong heng compressor.

I use a Yong Hang compressor and coudn't be happier with it. Yes, I did purchase a filter for 30 bucks but have been using this compressor for over 7 months with no problems. I am also airing up my friends tanks so it has gotten a lot of use. I have changed the oil maybe 4 times after using for gosh knows how many hours of use. If it craps out tomorrow I would just buy another. Good Luck whatever direction you go.



Luck! Russ
 
I am happy with my Yong Heng. Total cost was around $300 with all the external filtering riggings. The set up may not be able to produce breathable air but certainly clean enough for our toys.

Yes, it's made in China but I don't have any problems with that. Some see Chinese products as disposable items because they break down some times but I do not share the same view. Just recently there has been numerous reports on this forum about $2K worth Daystate compressors breaking down as well. Some just didn't work well right from the beginning. The important thing is whether it can be fixed when it breaks down. At less for me this is where the Yong Heng shines because the construction of the compressor is simple so you can service it all by yourself. Spare parts are readily available at very low cost. No more worries about support. 

If you decide to buy one, make sure that you get one with the new-version first-stage piston which has got a thicker top. There has been reports on the top cracking after some use although it has not happened on mine.
 
I bought the shoe box i think it was $540 including shipping i had a good size compressor allready ( but a pan cake compressor for $100 )i spent $120 on a 3 stage filter which is actually 3 in a row and the last one has dessicant before i use it i put the dessicant on a paper plate in the microwave for about 3 minutes or untill it turns blue then i give it 5 minutes to cool off then pour it back in and let it roll i have a 75cu ft tank if its at 3500 psi it takes it about 2 or 3 hours to refill i dont pay attention to it shuts off on its own i have a 30 gallon compresor and it kicks on about every 15 or 20 minutes i think for my situation its perfect


 
The Yong Heng gets my vote. I bought one last year and probably have 40 or 50 refills on my 90 cubic inch tanks. About $225 on ebay, It comes with a cheesy short filter setup, you can add more filtration but I haven't found it makes much difference. If you want breathable air in your gun, go to a scuba shop. Whole lot cheaper. Small tanks, about 11 minutes from 3000 to 4500 PSI.

Secret is to clear your water and oil accumulator valves every 3 minutes or so. That prevents build up that the filters must use. I live in a fairly dry climate (Desert west), so water isn't nearly as much of a problem as other folks deal with. In Minnesota, you might deal with a touch more humidity than me, so a desiccant filter might help. I have one, purchased on eBay for around $20. 

Make sure you buy the 110 volt version unless you have a 220 outlet available. You'll need a 30 amp circuit, as it's rated for something like 27 amps. 5 gallon bucket for cooling water and if you run for a long period of time, nice to have ice blocks in the freezer to cool the water, or a way to refill the bucket while it's running. Really is a fairly simple setup.

Having your own compressor really allows freedom to shoot. Before compressor, I really rationed air because I had to drive across town to get tanks filled and they could be real jerks about the whole thing.

After compressor, I could spend hours on the chronograph without worries. Made degassing my gun for maintenance less traumatic by far! I hated wasting air!
