PRODUCT FEATURES:
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.

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 depressuring 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.
