Innovative extraction arms online
Purex International are now offering their dust and fume extraction
arms as a new product range that is available from their website.
A large variety of arms, nozzles, cowls and connections are available
depending on the application which can include; laser processing, laboratory/cleanroom
work, medical procedures, soldering, welding and glue/solvent use.
The website shows full technical details and prices, the range includes 25, 38 and 100mm Flexible Arms, Plenum
extraction chambers and Cleancabs but of particular interest are the 54mm
Multi-Position Arms, which feature a patented joint design to ensure
reliable positioning, time after time.
The joint has been designed to overcome an inherent problem with other
Multi-Position Arms, which is that over time their joints lose the tension
between each of their halves causing the arm to slip. Consequently the
extraction nozzle could: -
- Drop into the path of oncoming product if used for example on a laser
marking line
- Knock over bottles of chemicals in a laboratory.
- Damage the product being worked on, for example a PCB in a soldering
application.
- Be dangerous if used in a medical procedure.
A spring loaded tensioning bolt enables the operator to tighten the Purex 54mm arm using minimum force, creating a positive lock between serrated
inner cams on the inside of the joint. Once set to the correct tension,
the position of the arm can be adjusted without unscrewing and re-tightening
the bolt. The spring action allows the cams to ride over each other and
click back into place as the arm is rotated, relocking the new position
automatically.
Most of the arms can be used with an existing extraction system by using
a suitable conversion kit or alternatively extraction and purification
units are available from the Purex range. For further information
