Hi Michael, I just thought I would give you a picture of the arrangement of the nozzles in a "conventional" spray bar system - whereby you can see the "fans" overlap (which is good practice - to get good coverage)- and to do this the slots in the fans are slightly inclined to the axis of the spray bar - as can be seen in the picture - in the link below. If the jets "collide" - you usually just get a big dribble at the collision point. I haven't used "deflected nozzles" - but I imagine you have to set the vertical elevation of the neighboring nozzles at different heights - to avoid a collision of the neighboring jets. However, maybe your supplier can advise you on this. http://www.bete.co.uk/spray-nozzle-applications/coating/spray-angles Hope this helps.
