Fumes produced during electronic manufacturing not only poses a health threat to personnel but can also dampen production efficiency overtime. Purex systems help prevent damage to machinery while protecting employees from toxic fumes.

The soldering process itself can produce some, if not all, of the fumes in the list below. These fumes can cause occupational asthma, long term carcinogenic diseases and other serious complaints. The result of these illnesses can be expensive compensation claims from employees, long term sickness and poor employee relations, plus heavy penalties from enforcement agencies.
  • Carbon Monoxide
  • Volatile Organic Compounds (V.O.C)
  • Abietic Acid
  • Pimaric Acid
  • Aliphatic Aldehydes
  • Hydrochloric Acid
  • Isocyanates
  • Isopropyl Alcohol

Processes requiring fume extraction include:

  • Reflow Ovens
  • Selective Soldering
  • Wave Soldering
  • Hand Soldering
  • Rework, Repair and Education
  • Laser & Robotic Soldering
  • Underfill
  • Conformal Coating
  • Printing
  • Solvent Applications

The Solution

Our fume extraction systems are designed in conjunction with some of the worlds largest Contract Electronics Manufactures and Equipment Providers to help:

  • Prevent damage to production machinery.
  • Reduce downtime for cleaning and maintenance
  • Protect personnel from harmful fumes.
  • Reduce product rejects due to poor production performance.
  • Maintain a constant extraction rate to ensure stable temperature profiles.
  • Deliver long filter life.
  • Interface with the production equipment

Notes:
1. The selection is based on the use of a standard connection kit.
2. Longer pipe runs may require a larger extraction machine.
3. * Point-to-point soldering machines only, not suitable for handheld tip extraction.
4. Continuous use may require a machine with larger filtration capacity.
5. Contact us for further advice.
6. IMPORTANT: Choose a vacuum control machine for Arm and Tip extraction and a volume control machine for other applications.

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.
X  Unit not usually specified for application.
O 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.
