BenchVent BV400-DFE

The Digital Control System offers both the performance and inbuilt safety features to help ensure people are protected from hazardous fumes. The status of the system is shown on a clear graphic display which is simple to use and easy to understand.

The BV400-DFE will work with upto 6 x 38mm arms, 4 clear Cowls or upto 30 on tip solder extraction.

Some of the features are:

An 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.

 

The extraction airflow can be set to the optimum level for the application, the 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. The graphic display shows you the real-time actual airflow so you know precisely how the machine is performing at that time.

 

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:

Filter blocked
Gas alarm
Particle alarm
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.

Motor Run

Shows the operator when the fume extractor's blower is running.

 

Safety Sensors:

These 'Digital' fume extractors incorporate a gas sensor in the exhaust to protect workers. The sensor helps ensure that gas from the process cannot pass through the extractor, into the wokplace without an alarm being triggered. A gas escape may occur if:

Filters are saturated
Filters are damaged or missing
A seal is damaged
The wrong filter has been used
The sensor is also used to warn the operator when the chemical filter needs replacing.

Particle Sensor

These 'Digital' fume extractors incorporate a particle sensor in the exhaust to protect workers. The sensor helps ensure that particles from the process cannot pass through the extractor, into the wokplace without an alarm being triggered. Particle escape may occur if:

Filters are damaged or missing
A seal is damaged
The wrong filter has been used
Filter Status SensorFilter blocked icon for purex fume extraction systems

Fume generated by the process will slowly block the particle filter over time. When the particle filter is nearly blocked the fume extractors will warn the operator with an audible chime and the keypad will flash red.

This feature allows the operator time to acquire a replacement particle filter before the current one becomes completely blocked.

When the particle filter is completely blocked then the fume extractors will chime and the keypad will flash every second. At this point the particle filter icon will flash to show which filters may need attention.

Temperature Sensor

A safety feature to warn the operator if the fume extractor overheats.
