Does anyone know of a dustproof enclosure with exhaust fan that is more reasonably priced? It just doesn't seem like box with a power strip, filter and thermostat should cost $3000 but perhaps that is all that is out there.
Any input would be greatly appreciated. The projector we are using is the JVC DLA-RS45U
I can think of several options. Anything that isolates the crawlspace from the projector should work and since its out of sight, looks don't count.
1. Make the hole big enough to slide the projector into the wall from the front with a box on the other side. Use a grill on the theater side with a hole for the lense that will allow cooling air in and cut a hole in the box adding a filter for exhaust. Any square box big enough for the projector should work. Seal the box to the access wall.
2. Same hole, but wrap the projector in filter material with appropriate cutouts for wiring. If the projector is in a crawlspace, then why worry about the look of wrapping the projector with filter material. Tape the filter tight to the access wall.
3. Fully boxed projector with cutout for lense and cooling air brought through filtered accesses from the crawlspace and exhausted back out to the crawlspace. Seal the edges of the box up against the access wall.
The projector fan should be sufficient if the filter material is cleaned regularly. Also consider that the crawlspace probably has never been cleaned and unless the dust is disturbed it probably isn't being significantly circulated.
Just some thoughts off the top of my head.
