Hey Vid,

I've gone through this thread and the playfield thread and see that the compressor talks sometimes get a bit sidetracked. I need a compressor for other jobs at my new house, but space is at an absolute premium. When looking at different models, I also remembered that a compressor could allow for the 2PAC applications you've detailed. Again though, space. Also if I decide to move forward with a compressor that could be suitable for 2PAC clear jobs, it needs to be portable enough to get to the greenhouse left in the backyard by the previous owners.

You once said that the cheap HF air gun requires 6 CFM @ 47psi. I'm wondering about the outcome if you bend those rules. Enter the example compressor...

This is nice because...
A) it doesn't cost $1000 and meets the rest of the needs I have.
B) it can be wheeled up my basement's bulkhead, and out to the greenhouse
C) it (almost) meets your CFM/PSI requirement and has the Cast Iron construction you favor.

So if I went ahead with this, would it be able to one day clear a playfield if I ever picked up a project that needed it? I'm guessing from the 6CFM, 47psi requirement, the pressure is more critical of the two??? If so, it looks like the above link's compressor would only be providing about 5.65 CFM, not 6.0. Does this just result in a longer application process, or does anything else change (i.e. particle velocity, air gun performance) that makes this a no-go?

Larger air compressors lack the portability (and I don't have a garage ) so I'm seeing if this is a possibility. Thanks!
