Ductless Work Stations      Total Exhaust Work Stations

LFE Bench Top, Laminar Flow and Total Exhaust Work Station

      Standard features include:

•  Constructed from non corrosive white stress - relieved polypropylene, all heat seam welded construction, and tested.
•  Ergonomic sloping front for easy access and extended reach.
•  The work top is constructed from ½-inch thick polypropylene, segmented for easy access and cleaning.
•  The work top is perforated to enhance linear flow.
•  A standard 1-inch raised front lip prevents any spillage out through the front of the station.
•  Optionally, the station can be configured with slots just above the work top for quicker extraction of vigorous gases associated with etching processes.
•  The station includes a top located filtration system, with a brushless spark proof supply fan rated @ 1,200 CFM zero static pressure and one non-metallic HEPA filter for trace metals analogy.
•  The filtration system is powered by dynamically balanced motorized impeller(s) for excellent energy efficiency. The fan(s) is housed in a positive plenum, which is coupled to the HEPA filter(s). This design creates a negative environment around the entire inner top section.
•  The filtration system draws room air through a top located 90% pleated pre-filters, into its positive plenum, and through the HEPA filter(s), showering clean sterile air over the work top.
•  A 14-inch hinged clear heavy-duty acrylic front sash covers half of the 28-inch high opening giving the operator ample working entry.
•  The filter(s) will have an efficiency of 99.99% down to 0.3 micron particle size giving a class 100 environment.
•  A minihelic pressure gauge indicated the pressure drop across the main filter.
•  The unit will have a double hinged, heavy duty clear acrylic front sash, covering half of its opening.
•  Incorporated is a fluorescent light fixture, in a fume tight enclosure with all plastic hardware which illuminates the entire work top.
•  A blower speed control device is incorporated to allow adjustment of the clean air velocity.
•  The unit has a removable rear plenum.
•  Configured for 120 AC 60 Hz or 220VAC, 50 Hz electrical requirements. •  Shipped assembled, fully tested and ready to use.
