The new extractors are shipped from the factory with ONE mains power outlet (which switches the vacuum on), and ONE blanking panel.
The blanking panel can be removed and replaced with one of three different modules:
1. A mains outlet, which behaves in exactly the same way as the fixed outlet (ie switches the vacuum on when power is drawn);
2. A mains outlet, which does not switch the vacuum on at all (ie a standard mains outlet);
3. A pneumatic module, which can be connected to a compressor & air tool, switching on the vacuum when air is flowing (ie when the tool is in use).
The two electric modules are around GBP35 each; the air module is around GBP140.
