Purex Solder Fume Extraction – Selector

Purex Solder Fume Extraction – Selector

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.

To choose the appropriate system please see chart at the bottom of this page.

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 Purex for further advice.
6. IMPORTANT: Choose a vacuum control machine for Arm and Tip extraction and a volume control machine for other applications.
