Compressor. Help plz!!!!!!!!!

[mehow86]

Hello all. I have this old champion comp. and it's taking forever to build up air, then once it does it wont last very long.....trying to sandblast my 94' ford bronco frame. Anyway, works fine for a few minutes and then starts to decrese rapidly. So someone told me to buy and extra tank which i did, and still no luck. I would like any and all forms of help.....thanks very much...mike

My opinion is that is compressor is a weee bit on the small size to be running a sandblaster without waiting for it to catch up.

As ancient as that is, it probably needed rings to begin with - but if you've been blasting around it with no filter on the compressor intake I'd almost guarantee that it does now...

ok, what size comp. is good to use?


ok, have to look into a filter for that.....thanks guys

look at the air requirements of your blaster and go from there, try and get something that will be big enough to run all the things you want and add a little to it. Sandblasters are CFM hungry units.

Like the others said running a filter is a good idea and that compressor may be tired. Also how many gallons is the tank?

One of these will keep up with a blasting project quite nicely I'm really not being a complete *** (just a little bit)... if you have a one-time high air consumption job like blasting something, it's not too expensive to just rent one of these for the day and not have to foot the bill for a huge compressor.

It's a good option as well. The last place I worked for rented compressors like you see above and larger (all the way to 3000CFM) and blast pots for large jobs, we also had the abrasives too. that may be some food for thought

ok. plz explain what CFM IS?

Cubic Feet per Minute. You could also see Standard Cubic Feet per Minute. Any compressor will have a rating of ** CFM at 100psi and ** at 120psi. Your motor is only 3/4 horse, that is not much by todays standards. You need modern compressor either way. How big will depend on how much sand blasting you are going to do in the future. What type of sand blaster is it?

Definitely too small for blasting. Looks like it's just a 1 cylinder, single stage pump. For blasting I would suggest a 2-stage compressor with a minimum 30 gallon tank, but most have a 60 gallon tank. (Thats "2-stage", not "2-cylinder", there's a big difference.) As stated above, try to find out the CFM and pressure requirements for the blaster, then get a compressor rated 25% higher than what you need. That way you're not pushing the compressor to it's limit. You have to account for pressure loss depending how far from the compressor you are, and the size and length of hose. Also you'll have to make sure you have enough power to run it. Most 2-stage compressors have at least a 5hp motor. That's a lot more draw than a 3/4hp.
