Air bursts from rotor head

I need some suggestions... I have a newer system (3 wks old) and the backyard zone has 6 rotor heads on it. The problem is the one right outside our bedroom window is the only one that bursts air (like when you turn a garden hose on) periodically for the first 5-7 minutes the zone is running. This head is the lowest one in the zone, so I don't know if that makes a difference or not. At 4am in the morning, it will walk you right up with the loud air bursts. I have irritrol 450 rotors. Is there any way to resolve this??? I would expect a burst or two, but not multiple ones for 5 minutes or more. It does spray plenty of water during that time, it just spits out air bursts (loudly) every 15-30 seconds. I have about 80psi coming out of the house so I don't think it is starved for pressure. None of my other zones do this... Ideas??? ?(

Since the head is on the low point of the line, I'd suggest installing a rotor with a check valve built into it. That way the pipe wont drain in that location and you'll have much less air in the line.
If I can't fix it, it's broken!
