Vari-Colour Fume Extractor Control System
A budget version of the Digital system but with many of the same excellent
features. This system is supplied on Laserex Alpha and Xbase fume extractors
as well as on other machines such as FumeCubes.
Features include:
AUTOMATIC FLOW CONTROL
Essentially, automatic closed loop flow control ensures that the extraction
rate remains constant. It does this by slowly increasing the speed
of the blower as the filter begins to block, this overcomes the resistance
to airflow through the filter and keeps the extraction rate constant.
This function is important because a falling extraction rate can cause
problems. For example:
- Particles can adhere to laser lenses causing expensive damage
- The temperature profile on soldering ovens can be affected
- People may inhale dust and fumes which escape due to weak extraction
- Products can become contaminated with dust
- Conveyors or equipment may need to be cleaned more often to prevent
breakdown
Another benefit of flow control is extended filter life which means
lower costs and less downtime for filter changes.
SPEED CONTROL
The extraction airflow can be set to the optimum level for the application,
the Purex fume extractors will then adjust the blower speed until the
actual airflow
matches the target airflow and the Flow Control system keeps it at
that level.
This is particularly useful when an extractor is fitted to equipment
such as a laser or reflow oven that specifies an exact extraction
volume to operate.
INTERFACING OPTION
The fume extractors alarm signal can be interfaced with other equipment
such as a laser or wave soldering machine to stop the process, set
off an alarm
or perform another function such as turning on a beacon. Alarm signals
can include:
The fume extractors can also STOP/START automatically with interfaced
machines. A run on timer is also available to ensure dust and fume
is extracted after the process stops.
VariColour filter monitor
This clever system monitors the particle filters in the fume extractor.
How it works:
- Green Light = Filter OK
- Amber Light = Filter will need to be replaced
- Red Light = Replace filter
