• Spray guns are designed for fast and even application of liquids, corrosion inhibitor and paints, for instance. Used for washing and cleaning hard-to-reach units, a soot filter and catalytic converter, in particular.

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.

Tips on using air spray guns

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’s recommendations to choose a proper mode of the device.

It is also necessary to make sure that the liquid you’re going to use is suitable for the tool. For example, it is forbidden to use air spray guns fitted with an aluminium body for applying agents containing trichlorotrifluoroethane, dichloromethane or solvents based on halogenated hydrocarbons because of health risks.

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. It is forbidden to spray compounds near an open fire: it is fire hazardous. It is not allowed to direct a stream on unprotected areas of the body: you can damage your skin.

It is required to make sure that air spray guns are intact, hoses and fittings are sealed. It is not acceptable to use damaged parts.
