This is  the new G30 with the new NVLD system which still has problems,,,,lol,,,,yes this system still having problems. Here’s the old and the new NVLD ,,,,the new system was changed the new NVLD and dust filter all come together with the pipe.,,,,before you had to get the NVLD and dust filter separately ,,,,then you would have to put it all together ,,,,this is a better setup. This is the best part,,,finally my people designed something which was a long time coming,,,,a new hose release made simple,,,,all you do is move that tab with your thumb and pull the hose off,,,no more trying to squeeze the 2 tabs and pull the hose off,,,,,this was so simple and easier.
