I use a Viair 460 compressor and an air tank I got from Bunnings..
Compressor pumps tank to 110psi and I can turn the locker on & off all day (30 times or so) and still have 80 psi in tank so the compressor only really has to run to pump tyres up.
Viair 460 is rated at 1.66CFM @ 100% duty cycle.
Bunnings recharge tank.. $49 complete with gauge, pressure release & Schrader valve so it is easily filled at a servo if needed.
