Assuming you don't already have one here is the manual:

I am not sure I understand what you are talking about. Are you refering to the power jet nozzle? Or is this something that you would purchase seperate from the filter?

thanks. I keep seeing mention of a venturi nozzle or whatever listed on alot of sites and was wondering what it is. What is your opinion of this line of filters?
