Great question, lets settle it. The new and only replacement turbine for TurboCat is from China and will NOT work right with the older Canadian made TurboCats. The turbine will rub on it, the fit is not right. Sorry to say but if you need a turbine for older TurboCats you will need to buy a new China made TurboCat or TurboCat Zoom. This goes for all versions such as TurboCat II, TL2000, TP210, etc. Also, note that you can take this chance to buy a new electric hose and tool kit.
