Thread: paint prep questions

hey there paint gurus........ couple of questions for you. is it possible to hook 2 compressors to a single line for a hvlp gun(a 5 psi and a 8 psi)? would that raise the cfm? and what minimum length long board should i get for blocking? this place has been a wealth of info and am looking forward to learning more in the future........ thanks, john

I use two compressors, plus an extra air tank, to assure I have lots of air, and also so I won't be shut down completely when a compressor wears out.

I usually buy 5-6 HP oiless compressors with 25-35 gallon tanks. You can usually buy them for about $300-$400 each.

I think the standard long board is about 17 inches, which is what the paper is precut for.

thanks hrp, do the compressors have to be oilless?

no- but try and get the same capicites on the holding tanks if you can, and if you get a diaphram style watch out for inline moisture.
You can also use a holding tank for extra air- such as a converted hot water tank- you will want to air this up outside to check for leaks before using indoors.
