Trotec's VENT line of exhaust fans ensure the efficient removal of dusts and gases, without cleaning them of dust particles or filtering odors with activated charcoal – perfect for the most basic laser exhaust system needs. The VENT line can also be easily scaled to support new requirements as your laser needs change. For instance, a prefilter unit (such as a mechanical prefilter, PowerJet-M or PowerJet-S) can be installed at any time to collect dust.
