The principle of metal laser cutting machine processing metal sheet is to irradiate the sheet metal surface with high-energy laser, and the high temperature makes it quickly melt to achieve the purpose of cutting. In the process of metal laser cutting, high-temperature burning of metal will produce a small amount of exhaust gas. In order to ensure the safety of the operator, there will be certain requirements for the ventilation system. HSG Laser recommends two ventilation methods as below.

1. Exhausting Treatment.Customer can choose whether to configure exhaust equipment when purchasing a metal laser cutting machine. The general exhaust system is composed of 4 parts: air collection hood, air duct, purification system and fan. It mainly uses airflow to treat local exhaust gas to make the work place not contaminated by harmful substances and maintains a good air environment.

2. Full Ventilation.This method is a relatively simple and convenient way. It uses accelerated air flow inside the work area to achieve harmful gases dilution in the air. Generally, an axial fan is installed on the top of the working chamber to discharge the internal exhaust gas. This method Is the most common method.

It is very important to choose the ventilation method of the metal laser cutting machine reasonably. If there are too many equipment, HSG Laser recommends that the “Exhausting Treatment” is the best.
