This is LEMATEC's Air Filter with a regulator. It is designed to be used with air tools, for example, spray guns and sandblasters. The inline filter system attaches to the air hose, capturing any dust particles or other contaminants before they can reach the tool. This reduces wear on your equipment.


The filter works by trapping all the water coming through it, which means that no matter what you are doing - spraying paint or sanding a piece of furniture, always keep the air dry.

Inline air filter and oil water separator with a regulator. This is an excellent accessory for spray gun users to keep their equipment running at peak performance!
