Rotors

I just purchased a pair of drilled/slotted rotors,and I am somewhat confused over the L/R packaging.I understand they are directional and only fit one side or the other,however it seems to me that the markings they have are reversed....instead of expelling pad dust/material out the outer diameter of the rotor,they have them so the material would be sucked inward.If someone could post a pic of their installation it would be appreciated.
These are "Autopart International" rotors,and they seem to be very heavy compared to the non drilled/slotted ones I have handled.I am impressed with how thick they appear to be.

You saying the slots would be rolling and basically hooking air in? Could be right...would suck in dust, but would also suck in air...personally I think they look better arcing outward the opposite way, but double check the rotors labeling...

some are and some are not...

My BAER Decela rotors ARE directional. They come with a letter inside saying you have to mount them this way or they may warp or wear out prematurly.

My powerslot rotors had L and R markings also. My slots face opposite of CRJ's...
