The compressor you use/suggest, delivers 72L/min. The statement in the FAQ says 110L/min, but i guess, it's playing safe here. Probably you're running two machines on the exhibition with only one compressor, right? So, how much L/min might the machine really need (and to be safe).
This thread has been helpful. I'm hoping something this small would suffice for the machine I ordered (VP-2500DP-CL32 ) . I'm trying to go as small as possible as space is a premium.
