A. Filter I.D. Window: A strategically placed front cover window shows the installed filter part number and installation date for convenience and to encourage timely filter replacement.
B. Air Velometer: An analog air velocity meter in the field of vision of the user provides independent backup to the electronic airflow alarm.
C. Double Hinged Self Locking Front Sash: When closed, the cabinet sash protects the operator with 100 FPM airflow. The sash is easy to open and latch.
D. Control Panel: Electronic controls and displays include switches for the blower and lights, an electronic hour counter and low airflow alarm, all located on a convenient front surface panel.
E. Steel Support Frame: The chemical resistant epoxy coated steel frame adds mechanical strength. Optional all polypropylene construction is available if desired. The pre-filter can be changed while the unit is operating to prevent operator exposure to chemical vapors.
F. Electrostatic Pre-Filter: The A 99.5% effective electrostatic pre-filter is accessible from inside the chamber to contain the release of any particulates that it traps.
G. Pass Through Ports: Electrical cords and cables are safely routed into the cabinet through ports on the back and side walls
H. Air Sampling Port: A filtered air sampling port allows manual filter monitoring.
I. Color: The cabinet is white; side and back panels are clear.
J. Airflow Alarm: A continuous air velocity monitoring system alerts the operator upon unacceptable values.
K. Manual Speed Controller: The operator may set the centrifugal fan motor speed as desired.
L. Dynamic Filtration Chamber: The dynamic filter chamber prevents any possible leakage of contaminated air by pressurizing the fan plenum (positive air) and depressurizing the filter compartment (negative air).
M. Stand: Optional mobile cart with locking casters.
N. Safety Filter: The optional carbon or HEPA/ULPA safety filter adds an additional layer of protection.
O. Work Surface: The internal work surface can be fitted with an optional polypropylene tray; see Accessories.
P. Filter Door Key: Filter access keys prevent unauthorized removal or accidental exposure to dirty filters.
Q. Track & Wheel System: The filter glides in on a wheel and track system, then clamps tightly against the filter gasket to prevent filter tears and maintain filter integrity.
360 Degree Visibility: Clear back and side panels allow ambient illumination into the chamber and provide users with an unobstructed view of its contents.
Standards Compliant: Performance specifications and construction meet or exceed OSHA, ANSI and relevant international standards to assure operator safety.
Construction: All models are available in either metal or polypropylene construction. See selection chart for specifications and dimensions. Specify metal or polypropylene when ordering. Available in 110v/60 Hz models.
