Neon lamps can be installed inside the hoods. They are watertight and airtight and have an IP65 protection level. A button has been provided on the electronic speed controller to switch them on and off.
Electronic controllers provide smooth, progressive speed adjustments for single-phase extractors, for both those inside hoods and those with extractor fans.
The baffle filters are in AISI stainless steel with holes along their perimeter to expel condensation.
