[QUOTE="pforsell, post: 495461, member: 7240"] According to the images the fan inside the gizmo blows the "dirty" air out of the camera through the central aperture. The replacement air gets into the camera through the "donut shaped" filters around the central "output" hole. In principle, it could work. In practice... well not so much. The fan is blowing air out of the camera (presumably all the dust too) but since it is only sucking air out of the camera the pressure difference cannot exceed one atmosphere even in theory. If the gizmo would pre-clean the air though filters, and after that really blow a stream of clean air into the camera, and then suck the dusty air out of the camera, the effect could be something useful. That would require a gizmo with at least two fans/blowers instead of just one. Verdict: the apparatus is not worth even testing. It is a bag of hot (or lukewarm) air. :cool: [/QUOTE]
