The air pump is used for three basic reasons. The primary reason is to push fumes away from the laser's focal lens. This protects the lens from contaminants which could destroy the lens. 

The second function of the air pump is to push air into the material's kerf as created by the laser beam. Air that is applied to the kerf will remove debris/fumes and allow the laser light to penitrate deeper through the material. The third reason is that the air will help to cool the material. If the laser cut/engraved material stays hot, then it could warp or shrink. This air pump is a diaphram style which does not require oil. Oil or water in the air line could be projected directly onto the focal lens. This air pump has a higher air flow rate and is quieter than other piston stroke designs.

We supply different air pumps for lasers.
