Hello guys, I would like your opinion on some ideas that we had .. one of these ideas is this filter ...
The GRID Filter is an accessory that allows RedUsers use their Epic an Scarlet cameras in extreme conditions ... The filter prevents you from the clustering of dust or sand on the inside of the camera, protecting the functioning of the camera ...
its very useful in extreme situations, such as beaches, deserts, rallies and other situations in which there is too much dust in the air ...

Hey Nicholas

I may be after something like this with a 3day shoot in sand dunes & subjects low to the ground. I reckon 2 issues

1) How much airflow does this inhibit?

2) By the looks of the pics your using strong magnets to mount the filter to the body. Can this create problems for the sensor being so close ie what does Red reckon?
 
Ive been looking for something like this for a while. If Red approve it then id fit them to all our cameras. We are always in remote dusty areas and looking to keep the environment out of the works.
 
From all reports, the fans are completely sealed from the inner workings of the camera. Given that this would simply stress the fans, wouldn't it be simpler just to blow the dust out periodically?
 
Nick - VERY cool design. Kudos.
Yah if RED will sign-off then I would love one!

The cooling duct and fans are completely sealed from the electronics inside the camera, according to RED. This "filter" serves no real purpose but to restrict airflow IMO.

No thanks.
 
How much more hotter does the camera temp rise during testing?
 
hi,
in fact... in the tests we did the temperature didn't changed over a period of 1h.
this filter is the same type as those used in cases of server computers.
therefore does not block the air passing through the fan.
the purpose its to avoid not only the dust, as also solid residues such as sand and confetti to accumulate inside the camera.

I really could have used this on my last shoot with lots of potato flakes (snowflakes) flying around and getting in my Scarlet. Good idea!
 
The question is- have you done any testing on dust holding capacity? I used to work in the racing industry for a company that produced air induction systems. One of the biggest tests we used to do on filtration media was flow vs dust holding. Basically, a clean filter can flow tons of air, but at what level of dust holding does the flow degrade? I would hate to brick my camera due to a filtration media that did not provide adequate flow when dirty. How do you clean the media? Great idea though! Please take this as a valid question and not knocking your product.
 
Paid for my GRID a while back, never heard back anything. My paypal is my name.
 
Did you work with RED Digital Cinema to ensure that use of your product would not void the warranty?

Note: Someone earlier pointed out that once your filter begins to fill - and before you wash it out - the airflow could become restricted. That could lead to problems...

If you did work with RDC, have they endorsed your product?

Did you get permission to sell on this site (are you a sponsor?) or permission to use the images of a RED camera on your website?

Not trying to be negative, just want to help you avoid being jumped on by lawyers... Seems to be going around a bit recently...
 
As he said before, better the filter than the camera. if you fell that there is a lot of dust on the environment, just quickly unplug and make a fast cleaning and plug it again.. the cooling components are isolated from the electronics components, but if there is excessive dust accumulation inside the ducts, it may result in overheating because the air will not flowing.. and no airblower can make a full cleaning of the dust insite the heat sinks..
 
If you like to have a good flow of air but also a good filtration, you need to shape it. The filters are normally folded to balance the area needed for the filter-material. Extreme good results are given folded and spatially expanded. Like here http://www.knfilters.com/cold_air_intakes.htm

Well, that is based on my time as Motorcycle Race shooter (and part time mechanic if we traveled far.)

The folding and spatial shape allows even "dirty" to function fully. (Dirty -- always to a certain degree)

Just my two engineering cents ;o)

Interested - but shipping is (yike!) another $30 for a 1oz (?) item. ouch.
