How much are you paying for the filter kit for a NEC 2000C projector with specifications close to original? I understand the manufacturer had done away with the plastic frame filters which were OEM. Any truth to that?
Thanks
Lance

I've never seen a plastic frame filter in any NEC and I've installed gobs of them. The factory filters are of much higher quality than the Chinese versions. But because NEC wants so much $$$ for them everyone has switched over to the Chinese version. Generally, the Chinese filters for NEC are under ten bucks each.

Why? The openings are so large they pass large bugs and even moths! It's like the filter that will never ever clog up though... but other than sheets of paper and tools what will it actually filter out?

You got to be kidding...

Mark, those are not Barco's filters or if they are they are not the current ones.

Yes, the Barco/Kinoton filters are completely different, but these pictures from Mark show the ones that Gordon mentioned for Christie and NEC I think. Looks like a joke to me.

Yes, that's the NEC filter. Like a coarse woven door screen basically. It's gonna let everything right on through.

Are those for the lamphouse inlet? Maybe NEC decided filtered air was not needed for the lamphouse. Obviously those are just for preventing someone from dropping items in the projector.

Marco...

They are available for all styles of NEC filters. I would never use them around here. In this Desert area there is way too much dust and dirt.

I have tested ALL the available filters for NEC over the long term and the filters sold my MIT are by far the best. They fit really tight and seem to seal much better than any of the others out there. AS a result all of my customers will be using the MIT filters or the original NEC filters which always worked fine.

The following images are of a projector that has run with the crappy Strong filters for about three years. Note that the top of the light dump heat sink is nearly plugged up. This entire light engine had to be pulled and cleaned including the area between the light input prism and the actual light engine prism itself. It's not too difficult to pull a clean microfiber rag though that area and get the crud out. The light engine prism itself is sealed in a way similar to how Barco seals theirs. None the less there is a fan right above this engine blowing anything that can manage to get into the projector right into the light engine proper.
That internal fan absolutely needs a heppa filter on it to obviate this sort of issue and I am working on getting a filter that fits it.
Customer was lucky this was only dust and not mixed with popcorn oil or it may not have been possible to clean it on site.

After cleaning it up....

Even the heat exchanger itself was about 60% plugged up. A straw taped to a shop vac clears this crud out easily.

Well i don't know where you got that Chinese Filter from but the ones we bought dont look like that
They have a very fine interior matrix mesh between the two outer screens
so far we have noticed no increase with internal dust compared to the original Christie and NEC filters we used in the past

That's the one Strong supplies. You will learn the hard way after running with the mesh filters for several years! NEC charges $2500 USD JUST to clean a light engine and they have to be cycled through Strong or MIT. May as well add to all your grief you claim you are having...

Just curious to see if anyone has found a suitable 3rd party replacement for the NEC NC2000C filters. Specifically I would like to find the hard plastic frame with cloth baffles which can be washed and reused.

Strong's NEC filters are not OEM and I think the same is true for MITs. I doubt you are going to find many that want to make washables...nobody wants to clean them and those that do clean filters often do a lousy job. And a clogged filter is very bad. At least with a new filter, you know it is cleaned.
