Operating principle

Blow and tyre inflation guns have a similar design. When connected to a compressor, compressed air is supplied to the handle of the tool and, when the trigger is pulled, it flows to the nozzle.

Tools used for painting and sandblasting works come together with a special container. It can be attached either to the top or to the bottom of the tool. The way paint or abrasive agents are sprayed depends on the position of the container. If it is in the upper part, liquid or abrasive compound get to the air passage under gravity; when it is placed at the lower part, liquids are sucked in due to vacuum.

After unpacking the tool, you should keep the manual. It contains important information about how to adjust pressure, nozzle, fill the container, etc. Each time you use an air spray gun, it is necessary to read the manufacturer鈥檚 recommendations to choose a proper mode of the device.

It is also necessary to make sure that the liquid you鈥檙e going to use is suitable for the tool.

While working, it is very important to observe safety precautions. You should have protective goggles and a respirator on when painting or performing anti-corrosion, stone-chip and sand-blasting treatment.
