It sounds like the real issue is your compressor is not powerful enough, or the pressure is to low going to the piston. The "blaster" tank they are referring to is just a small perhaps 5 gallon tank hooked up in line between the piston and the compressor, your compressor charges the tank and the tanks pressure activates the piston.
I get mine at Harbor freight
make sure to have the pressure set right for the prop you are using, do not exceed the max PSI listed. put a regulator between the storage tank and the prop.
There are far better pneumatic guru's on the board than I, and I hope they fill in any blanks I might have left out .
