Sealed systems should only really get air in when draining the system and re-filling apart from that providing the system pipework is installed correctly and there are no leaks its not as often as an open vented system which is more prone to corrosion aswell.
Ok thanks thats what i meant do they oftern get them whn refilling? like open vented do.

All systems get air in them when re-filling, the system will only get so much full with water until the air has no where to go and then compresses and gathers in the rads until released via the vents. Airlocks can sometimes be there due to poor pipework or if your really unlucky just be there and be a pain to get rid of. When re-filling make sure you start from the bottom and work your way up
