    Default Canned compressed air

    Hi. Does anyone know where to get cheap canned compressed air apart from CP? Anyone seen or heard of a small compressed air machine that can be used for photographic lens cleaning purposes? Thanks!

    If i'm not wrong, modelling shops do have compressors or dry compressed air in cans for sale.

    When using compressors, be sure to have a moisture trap else you'll be blowing water droplets onto your lens/sensor.

    I have a air compressors for doing air brush, it was about $700 at 15 years ago, has moisture trap with it. (Did some air brush illustration and armour tank modeling kits)
    I think you can get air compressors cheaper from hardware stores, but it is the industry type, may need to get the smaller model and add a moisture trap.
    It is also good for doing cold laminating for photos.

    You can buy from PK computers in Funan center 4th floor, can't remember how much, I think it is about $18 per can, hope that they still have stock.

    Be careful when spraying into the lens or sensor, when the air is spray out, the can become cold and can cause condensation on the surface that you blow. Only do a short burst of spray.

    Challenger @ Funan.

    3M brand, $12.90 ea. 339grams.

    Not particularly powerful, and more for office use than for photographic gear. But I use for general dusting of the external surfaces of my gear. Good enough.

    always spray with can upright...spray with can tilted and especially upside down and you will have serious frosting...

    Not only keep upright. Must do a test-spray first. Sometimes some of the propellent can still be ejected out.

    its a glass with level gauge, then at the bottom of the glass is a metal tip that when u press will release pressure & water.

    From my experience, the canned air coming out is cold enough to cause condensation because of our humid environment. If you keep spraying the can for several seconds you will feel that the can will become cold and water will start to form on the container. So be careful how you use it!
