Please help me understand the projector enclosure

[Davidalaska]

Hi, my boss asked me to buy an enclosure for the projector located in the assembly workshop.Do you have any experience for this something new for me? I have also contacted one of the suppliers Deertv, it seemed meeting our requirements, but I have a question, how do I know the front glass won't distort the pictures? I was told that they use the very good quality front protection acrylic windows, the light Transmittance is around 95%. I appreciate your comments.Thanks.

Hmm guessing it's a dusty environment? What you probably need is a box that is fully sealed but has an intake and exhaust. Intake would have a HEPA filter. Though if you want to get fancy you can even have it draw and exhaust air from/to another room like an office. This is a good idea if it's high up, so it does not overheat.

I don't know if this is something you can buy, if not, it would not be that hard to make. I don't think you have to worry too much about distortion. If it was a camera, maybe, but for a projector I think it will be fine.

This use to be a big thing years ago with home theater enthusiasts whereby they needed to discretely deliver cooled air and take away heated air--and also the luxury of controlling dust. The professional enclosures all had the required first surface glass to in/pro-habit reflection and keep image distortion to a minimum.

If a glass face is included in the box I wouldn't worry about distortion or light, because it should be selected for that purpose. Projectors in the movie theater are usually throwing from behind glass, after all.

Thank you very much.
Yes, the workshop is dusty and humid. This enclosure has an intake and outlet with fan cooling system. As you said, it helps me eliminate the distortion concern.

Thanks for all your inputs for me. It is really helpful for me.

Thanks. I think it's time to report my investigate results to boss now.
