ESD - A potential hazard in dust and fume extraction
Many processes where dust and fume extraction is necessary take place
in an environment where electrostatic discharge can cause problems.
The actual process of air passing through an extraction system can create
a static charge. This charge can damage sensitive electronic components,
resulting in expensive reject rates. In applications where powder or dust
is mixed with the airflow, for example in the chemical handling and pharmaceutical
industries, a build-up of static electricity can pose a potential explosion
hazard.
To combat this, Purex International, in conjunction with customers
and research establishments, have developed Purex ESD (Electro
static discharge) safe air extraction and purification systems. A material
comprising of 30% stainless steel fibres has been used in the patented
knuckle joints and air flow valves to create earth continuity in the extraction
arms.
Purex systems are used in many applications where ESD can be a
potential problem, for example in cleanrooms, laboratories, circuit board
production, handling of sensitive components and reworking.
