That specific tool need 90 psi of air to operate correctly. My little 5 gallon air compressor (non-oil compressor) was running continuously in order to build enough air pressure, my 30 gallon (oil compressor) was more than enough. So, I think 15 to 20 gallon compressor would work, but it would likely run continuously for a while in order to keep the air pressure about 90 psi. I think this tool was designed for shop air with very large tanks with high air pressure. Home systems will work but will take a while and your smaller air compressor with run continuously, I did not want to my little 5 gallon non-oil air compressor to run for 10 to 20 minutes continuously. My 30 gallon air can run continuously for hours and it will not hurt the pump.
