Compressed Air
I recently bought a can of 'Air Duster' from Essential Electronics but the pressure from this product is too weak for any meaningful impact.
I need something to blow fine debris/dust from the voice coil gap in a loudspeaker. Recommendations please - need something with bit of oomph!

Re: Compressed Air
I have been using a Kennair Air Duster Kit (can + valve) for a long time to get dust off camera sensors. I have no way of knowing if this is better or worse than what you have.

Re: Compressed Air
Short of using an air compressor and blow gun which many of us have, I have a friend who showed me one of these:

Re: Compressed Air
I would use a vintage cylinder vac that blows as well as sucks. I keep our 40 year old Electrolux for blowing things dry and spraying paint. You need to bang the hose a few times first to dislodge dust from it.

Re: Compressed Air
Yes, but only up to about blood heat. A very excessive temperature might result in the can bursting. blood heat is only about the temperature to which the can would be subjected during storage or transit during a heatwave.

Re: Compressed Air
If it's just for a one off, one shot job, maybe consider using an inflated (spare) car tyre as your compressed air source.
It would need a certain amount of inventiveness to get the air to where you need it, but you could start with a tube borrowed from an old footpump and extend it, and have something like a flattened bit of metal tube inserted in the output end to give you an aimable 'jet' of air. |
