I have noticed that around the lens there is a gap to the inside because of this the airflow that comes in from the side sucks air also in from around the lens and i can see that dust particles also sucks in that way and it will accumulate everywhere inside
Would have been better if the gap around the lens was sealed ?
And also after maybe a year the inside will have clogged up whit dust what do we do about that ?
I agree. I live in a particularly dusty area and this is a problem with most devices I own. I think I might put some hot glue or a thin layer of black insulation foam around my projector’s lens.
I’m not sure sealing the gap will help, air has to and needs to be sucked in and circulated for cooling, whether it’s from the vents or a gap makes no difference and along with the air comes dust, so by sealing off this gap just stops dust from entering at one point only, dust will still enter from all other points with air to the inside, and you obviously can’t seal off all holes and gaps then it won’t be cooling and will overheat.
What I was thinking about was that if you only blow in air to blow out the dust, but don’t get rid of said dust from around the projector right away, the dust might circle back and land right back in and around the projector.
When I’m using any kind of compressed air to clean equipment, I make sure there’s also a flow of air away from the unit,either with a fan or with a vacuum cleaner at a shirt distance.
based on my knowledge, electronics and static dont gel well. Not sure if this is still the norm but I am sure that till few years back, people used to wear anti static bands while working on electronics.
I had a bad incident when i blew up a friends motherboard due to static after cleaning it with a vacuum cleaner. I’ve kept my electronics away from using a power blower ever since.
EDIT:
Did a quick google search:
There are special anti-static vacuum cleaner that should be for cleaning electronics.
Compressed air is definitely safer, but should be used from a distance .
That’s indeed correct, but that applies to all work with exposed electronics and regardless of vacuum cleaner use or not IMO. I just wasn’t aware that vacuum cleaners posed an increased threat, I always make sure I ground myself.
