Fume Extractors for Laser Coding & Marking

CO2, YAG and Diode lasers are commonly used to code and mark components or products which are manufactured from a variety of materials. Hazardous fumes and dust are produced when the substrate, lacquer, paint or coating is marked or cut. Purex systems not only help ensure compliance with International Health and Safety Law but also deliver actual cost savings to the production process.

Materials lased include: -

Purex Solution

Purex fume extraction systems are designed in conjunction with some of the worlds largest laser coding & marking system manufactures to:

• Prevent damage to the laser and components.
• Protect personnel from harmful fumes.
• Reduce product rejects due to poor laser performance.
• Maintain a constant extraction rate.
• Deliver long filter life.
• Interface with the laser

Machines for lasing PVC

Key:

Normal selection.
Select if extra filter capacity is required and/or additional airflow is required to extract from multiple lasers or heavy duty applications.
May also be considered.
  Unit not usually specified for application.
For lasing onto PVC.

Notes:
1. The selection is based on the use of standard connection kit.
2. The 800i 3 tier unit is designed for use where the application has low dust, but high gas emissions. The 2 tier is designed for applications producing high dust emissions.
3.  A poor enclosure is where less than 4 sides of the process are enclosed.
