Aircraft X checked on frequency out of climbing to 29;000 feet and stated that he was Non-RVSM.  There was nothing indicated in his flight plan that showed that Aircraft X was Non-RVSM.  There was also no coral colored box around the aircraft altitude.  Aircraft Y was in level flight at 30;000 feet on a course that I thought would clear Aircraft X.  I was still processing the fact that the Non-RVSM information from the plane and my display were at odds; so I failed to stop Aircraft X at 28;000 feet.  When I realized that the proximity was going to be too close; I turned Aircraft Y 20 degrees left.  During this time my Assist changed the equipment qualifier on Aircraft X to show he was Non-RVSM and conflict alert activated.  After separation was reestablished; Aircraft Y was cleared back on course. The pilot of Aircraft X stated that he had filed the same flight equipment numerous times and it kept showing that he was RVSM qualified when he wasn't.When a flight plan is filed it should give feedback to the pilot to show whether the altitude request is showing RVSM or NON-RVSM based on the equipment that is input.
An aircraft checked on to the Controller's frequency and advised they were Non-RVSM qualified. The aircraft flight plan suffix or radar data tag did not indicate they were Non-RVSM. The controller only used 1;000 feet vertical separation between this aircraft and another one.
