Swallow 4000

Filtered Fume Extraction System for Lasers

The Swallow is an air cleaner designed for the removal of particulates and gaseous contaminants and is typically suspended above the laser process workspace.


It is designed specifically for applications that include areas having high load particulate concentrations such as laser welding where direct source capture may be difficult. Laser fume absorbent canisters are also an optional stage of filtration to control odors and gases.

The 4000cfm unit (6800m³/hr) accepts multiple stages of air filtration where the user can select from a variety of particulate or gaseous/chemical filtration depending on the laser process.
