SFS STATIONARY UNIT WITH SELF-CLEANING FILTER The SFS is a wall-mounted filter unit that provides filtration for use with one extraction arm and fan. The SFS features a round filter cartridge. This filter cartridge is provided with a precoat to extend the lifespan and the efficiency of the filter. The SFS is fitted with a RoboClean system for automatic sectionwise cleaning of the filter cartridge by (externally supplied) compressed air. The dust and dirt particles end up in the dust bin. The SFS comes with an external pre filter (spark arrester) in a separate box. The SFS needs to be connected to a control box. product data sheet APPLICATIONS The SFS is intended to be used for the following applications: • MIG-MAG/GMAW welding (annual use: >700 kg/1500 lbs) • TIG welding • FCAW welding (annual use: >700 kg/1500 lbs) • stick/MMAW welding (annual use: >500 kg/1100 lbs) Do not use the SFS for the following applications or in the following circumstances: • arc-air gouging • aluminium laser cutting • oil mist • heavy oil mist in welding fume • extraction of aggressive fumes and gases (e.g. from acids, from alkaline, from soldering paste containing lithium) • extraction of hot gases (more than 45°C/113°F continuously) • grinding aluminum and magnesium • flame spraying • extraction of cement, saw dust, wood dust etc. • sucking cigarettes, cigars, oiled tissues and other burning particles, objects and acids • explosive environments or explosive substances/gases Physical dimensions and properties Colour: • Housing • Strip polypropylene • grey RAL 7024 • yellow RAL 1028 Supply cable (loose) Efficiency: • Pre filter • DuraFilter FCC-30 Filter class: • Pre filter • DuraFilter FCC-30 SurfacePlus precoat on DuraFilter FCC-30 • 65%<80% • >99,9% • G2 according to DIN EN 779 • M according to NEN EN IEC 60335-2-69 RoboClean filter cleaning system Required compressed air quality dry and oil-free according to ISO 8573-3 class 6 Required pressure quick connect coupling ¼ in. max. 60 nl/min.
