What options are available for fume extraction systems?

There are two basic options:

1. Vent-to-outdoors
2. Recirculating fume extractor

Vent-to-outdoors is a blower and a sealed duct system that removes the fumes from the laser cabinet and exhausts the untreated contaminated air outside.

A recirculating fume extractor (RFE) has an integrated suction blower that removes the fumes from the laser cabinet, treats the contaminated air within its multi-stage filters, and recirculates clean air back into the room.
