2.02 Materials:

2.02.01	Structural frame shall be constructed of extruded aluminum. All exterior 
surfaces shall be electrostatically epoxy-coated for superior resistance to both 
solvents and corrosive acids. Aluminum shall be properly prepared for epoxy 
coating.

2.02.02	Enclosures must contain a rear baffle, plenum, and air foil for maximum 
containment.  These features shall be constructed of epoxy-coated steel.

2.02.03	Enclosure must contain an aerodynamic Clean-SweepTM Air Foil, U.S. Patent No. 
6,461,233, to direct air uniformly over the work surface for maximum 
containment.  The air foil must have three rows of perforations, strategically 
placed to provide a protective barrier from contaminants.

2.02.04	 Enclosure must contain an Upper Containment Sash Foil.  This foil will be 
radiused to allow an aerodynamic entry of air into the enclosure and away from 
the user’s breathing zone.  

2.02.05	The sash shall feature a perforated air passage directly atop the sash foil to bleed 
air into the enclosure chamber and direct chemical concentrations away from the 
user’s breathing zone.

2.02.06	The enclosure must contain an Upper Dilution Air Supply to provide bypass air 
from above the work area. 


2.02.07	Enclosure must feature a Zoned-Perforated Rear Baffle, U.S. Patent No. 
6,461,233, that directs horizontal laminar air streams to the three-zoned sections 
of the perforated baffle in a single pass.  

2.02.08	The Enclosure shall have Side-Entry Air Foils, allowing turbulence-free air to 
enter the enclosure and allow clean air to sweep the interior walls of the 
enclosure through their perforated air passages.

2.02.09	The Enclosure shall feature an ergonomic front slope of 20 degrees on 22.75” 
high models and 14 degrees on 32” high models.

2.02.10	The enclosure shall feature a flush sash with Spring-Loaded Latch.  The sash 
features a wiping seal to contain contaminants.  The Latch shall hold the sash in 
an open position for equipment loading.  The enclosure shall allow a 20” 
opening (23” high unit) or 29.25” (32” high unit) for equipment loading.

2.02.11	Two utility ports, located at the lower rear below the baffle, shall provide for 
electrical cord or tubing pass through and shall be sealed with plastic plugs when 
not in use.

2.02.12	Sides, top, and sash shall be 3/16” tempered safety glass.  Materials such as 
acrylic or various forms of plastics are unacceptable.

2.02.13	Nominal dimensions shall be 24”, 36” or 48” wide; 23” or 32” high; and 29” 
deep.  The Enclosure must have an internal depth of no less than 23”.

2.02.14	Enclosures shall be able to exhaust from the top or bottom of the unit.  Exhaust 
connectors are available for either a 6” OD outside exhaust or a 5” ID hose.

2.02.15	Optional Guardian 1000 Digital or Guardian Jr. Monitors are available.  Both 
monitors provide audio/visual alarms alerting the user to low airflow conditions.  
The Guardian 1000 Digital Airflow Monitor also displays a face velocity value, 
provides an RS232 output, a night setback mode and auxiliary relay ports.

2.02.16	Optional Fluorescent light kits provide auxiliary light with an auxiliary outlet 
plug for supplying power to equipment such as a balance or printer.

2.02.17	Optional work surfaces to be of black solid epoxy for maximum chemical 
resistance.  Work surfaces shall be dished to contain spills.  

2.02.18	Enclosure shall incorporate a by-pass feature for efficient removal of 
contaminants located in the upper portion of the unit.

2.02.19	Face velocity measurements shall be within 15 feet per minute when taken at
