The HEPA filter manufacturer establishes the efficiency of the filter by challenging it with
an aerosol of known particle size. The number of particles that penetrate the filter are
quantified, and this establishes the efficiency of the filter.
Note:
HEPA filter media is very fragile. DO NOT touch the media. If you think the media
of a HEPA filter is damaged, DO NOT USE THE FILTERED HOOD. Have the HEPA
filter integrity tested by a certifier before using the filtered hood.
Note:
HEPA Filters are only effective against particulate material. Gases and vapors will
pass through the filter.
Neutrodine
®
Filters
Neutrodine filtration takes the guesswork out of carbon filter choices allowing
simultaneous handling of solvents, acids and bases with one comprehensive filter. The
backup (secondary) filter provides added safety after breakthrough and until filter
change can occur. Sensor package detects filter saturation and sounds an alarm when
unsafe conditions are detected. Intelligent filter identification indicates type (HEPA or
Neutrodine) and status (primary or secondary) to prevent saturated filter reinstallation
risk. Available with eGuard
software to monitor, manage and provide data via Wi-Fi or
Bluetooth connection to a phone, tablet or computer. Make sure to use only what was
reported in the approved LP questionnaire for safety purposes.
Fan/Motor
The fans, positioned between the two Neutrodine Filters, pull air from the room through
the sash opening of the filtered hood, through the filter protection and out the top of the
hood. By passing through both the primary and secondary filters, the air is clean
provided no alarms are present and all safety precautions are followed. The fans have
an operation range of 1,000 rpm to 3,000 rpm with two speed settings. In the eGuard
interface you can manipulate the speed of the fan when the sash is at operating height
and closed.
It is suggested that you keep the rpm settings no lower than 1,400 rpm for the Closed
Setpoint and no higher than 2,400 rpm for the Working Setpoint (operating height). If
your filtration technology includes a HEPA filter, the Working Setpoint suggested is
2,600 rpm. See
Front Airfoil
The location, size, and pattern of the airfoil openings in the work area affect filtered
hood containment and performance. The front airfoil profile, and air intake openings
play an important role in establishing Directional Airflow, as described previously. A
flush foil is also available as a factory installed custom only. The air foils feature Clean-
Sweep™ openings that create a constant barrier from contaminants. In addition, should
the operator inadvertently block the airfoil holes, the air continues to enter from under
the air foil and through the Clean-Sweep openings.
