Have you checked with the people at Home Depot? They should have
everything you need.

All you need for connection is a male air hose quick connect
fitting. That you should be able to find at any auto parts store,
HD, or online. Harbor Freight Tools has them cheap. The fitting
has male pipe threads, generally 3/8" on the other end so you just use
whatever pvc plumbing parts necessary to make up either a permanent or
temporary fitting that you can connect to your system at the
appropriate spot. I added a permanent one together with a ball valve
to my system.

Whether you can successfully blow out the system with a small
compressor is a different story. I do mine easily with an old Sears
shop compressor,that has babye a 15 gallon tank and does 9 CFM at
40psi. I let the tank get up to about 80psi, then turn on a
zone. I only have 3 rotors per zone and 7 zones so it works OK.
Used it one year on a friends house that had 10 zones, from 6 to 10
heads per zone. That was much more difficult and took a very long
time because these smaller compressors can't deliver the air volume to
do it effectively and quickly. The pros use large gas powered
compressors that can blow out several zones at once in a couple
minutes.
