how many fills from guppy 88 cu in to fx crown

some imported

compressors fail yes some are junk I have been threw it , but wow pumping a impact is too much for me by hand . hw about starting like we all did first start with a tank and have it filled then go to a compressor atleast this is how I did it now I have a compressor a big 97 cuft full size tank and a guppy which holds like 90 cuin , for 2 fills out in field or in my car or at the range here



BTW I did have my china compressor from Modair for 1.5 yrs but I repaired it till I shot it , but to fill a big tank was a nite-mare the air-max i got now fills a big tank in like 5 min fills a gun in 30 seconds .

and I never looked back , I learned buying cheap junk costs more in long run who else agrees ?????

I agree, in most cases spending more up front will save money in the long run. I bought an Omega compressor from AOA and so far it has been trouble free (knock on wood), but I only use it to fill my guns. I don't own a tank at all. I usually take two guns when I go out and at 40-50 shots each it's more than enough for a full day's shooting for me.

I didnt have enough info to run the numbers but this calc. is self explanatory :

If you have a shop compressor "boosters" , shoebox & altros, are slower filling but simple & reliable.

88cu/in isn't a lot of air i believe the bottle on a crown is 480cc you need something larger imo. btw i have a Chinese compresor for over 6months now i use to top off a 109cu/ft carbon fiber tank and it has worked great for me. I bought it on ebay for 300.00 delivered. It will fill my impact in like a minute but i dont use it like that i like filling off my tank better its a more accurate/slower fill from the tank.i get around 20 250 bar fills from my tank that i fill from the compressor. it takes like 30 to 40 minutes to top off my large 109cu/ft bottle.
