What is the purpose of the Konig air blower?
It was made to blow debris from various areas of photographic type equipment and many people use items like this when trying to clear marks from their sensors.
What does it look like?
Visually the shape is a bit like a rugby ball or a grenade. The red plastic pipe on the end directs the flow of air onto the subject.
What is it made of?
The tube is of plastic construction and the blower part itself seems to be rubber - the smell of it is slightly unpleasant and reminds me of swimming caps.
Is the build quality any good?
There aren't too many parts to the construction so in theory it should be easy to make a quality product. At work we have a couple of these that are around a couple of years old and the rubber is perishing - the blower still works, but as it's compressed you can see splits in the rubber which are only going to continue getting worse over time, eventually rendering it useless.
Does it do the job?
Well that all depends on what you're trying to clean with it! The blast of air delivered is reasonably powerful, but nothing like a tin of compressed air and as such it isn't capable of removing anything stuck to a surface or wedged behind different componenets. When it comes to using blowers for camera sensors it isn't really something I'd recommend for the following reasons:
a) quite often dust gets stuck on sensors so this won't shift it and you'll need a sensor swab
b) blasting air around the small confines of a camera interior will often just result in other particles being shot around the inside, these could land on the sensor making it worse than before (an air canister with a suction attachment is more appropriate).
Is it cost effective?
Well seeing as I can't think of a use for it that can't be done better with something else, I'd have to say no. That said if you want one, you can buy these on the highstreet for around £8.
