Ah I see, yeah this is an after market (3rd party??) NW I saw on a few sites within the past couple months that claims to eliminate the start up issues, although it also eliminates a ton of air pull as well which I don't know if I'd be particularly happy with, I can live with restart issues which 80%* more air , because its on way longer than it's ever off.
*pieced together guestimation based upon some mfg specs I've seen
